## Об API

Отправляйте запросы на `https://api.transcript1.com/v1`.

- Тело запроса и ответа имеет формат JSON. Имена полей записаны в `snake_case`.
- Даты приходят в UTC по ISO 8601: например, `2026-10-13T09:30:00.000Z`.
- Длительность записи и временные метки транскрипта измеряются в секундах.
- У ошибок единый формат — см. [«Ошибки»](https://transcript1.com/ru/docs/api-reference#errors).
- В ответах на запросы с аутентификацией есть заголовки `X-RateLimit-Limit` и `X-RateLimit-Remaining`. Их значения описаны в разделе [«Тарифы и лимиты»](https://transcript1.com/ru/docs/billing-and-limits).
- При `source=auto` сначала ищем подходящие субтитры на языке оригинала в YouTube, X, TikTok, Bluesky, Dailymotion и LinkedIn. Если их нет, распознаём речь. Режим `captions` (только субтитры), то есть `source=captions`, не скачивает аудио и не переходит на STT: без подходящей дорожки задача завершится с `no_captions`. При `source=stt` или определении говорящих субтитры не используем. Какие дорожки доступны, как их получаем и где есть пословные временные метки — в разделе [«Источники и параметры»](https://transcript1.com/ru/docs/sources-and-options).

Спецификацию OpenAPI можно скачать в любом из двух форматов:

- [JSON](https://api.transcript1.com/v1/openapi.json)
- [YAML](https://api.transcript1.com/v1/openapi.yaml)

## Доступ к API

Перед каждым запросом добавьте ключ или токен в заголовок: `Authorization: Bearer <token>`.

- **API-ключ** с префиксом `t1_` даёт доступ ко всем эндпоинтам. Создайте его в личном кабинете на странице [«API keys»](https://transcript1.com/dashboard/account/tokens).
- **Токен доступа OAuth** начинается с `t1o_`. Такой токен получают MCP-клиенты, например Claude и ChatGPT, когда вы их подключаете. Доступ ограничен разрешениями `transcriptions:read` и `transcriptions:write`.

| Разрешение | Доступные запросы |
|---|---|
| `transcriptions:read` | `GET /v1/transcriptions`, `GET /v1/transcriptions/:id`, `GET /v1/transcriptions/:id/upload` и `GET /v1/account` |
| `transcriptions:write` | `POST /v1/transcriptions`, `DELETE /v1/transcriptions/:id` и `POST /v1/transcriptions/:id/upload/complete` |

- Если у токена нет нужного разрешения, API ответит `403 insufficient_scope`.
- Если ключ или токен не передан либо недействителен, вернётся `401 unauthorized`.

Для отправки частей файла действует другой токен. В запросах `PUT /v1/transcriptions/:id/upload/chunks/:index` передавайте `X-Upload-Token`, полученный при создании загрузки. Подробнее — в разделе [«Загрузка файлов»](https://transcript1.com/ru/docs/uploads).

```bash
curl https://api.transcript1.com/v1/account \
  -H "Authorization: Bearer $TRANSCRIPT1_API_KEY"
```

```javascript
import { Transcript1 } from '@transcript1/sdk';

const t1 = new Transcript1({ apiKey: process.env.TRANSCRIPT1_API_KEY });
const account = await t1.account();
```

```python
import os
import requests

response = requests.get(
    "https://api.transcript1.com/v1/account",
    headers={"Authorization": f"Bearer {os.environ['TRANSCRIPT1_API_KEY']}"},
)
print(response.json())
```

## Идемпотентность

Добавляйте `Idempotency-Key` к `POST /v1/transcriptions`. Тогда запрос можно повторить, не создавая ещё одну транскрибацию.

Длина ключа — от 1 до 255 символов. Он передаётся только в HTTP-заголовке, не в query-параметре.

- Если ключ и параметры не изменились, API вернёт прежнюю задачу и не спишет минуты повторно.
- Если ключ прежний, а параметры другие, API ответит `409 idempotency_conflict`.
- При загрузке по частям можно повторить запрос создания с тем же ключом, чтобы получить свежий токен загрузки.

```bash
curl -X POST https://api.transcript1.com/v1/transcriptions \
  -H "Authorization: Bearer $TRANSCRIPT1_API_KEY" \
  -H "Idempotency-Key: 5f1c2b0e-8d4a-4c3e-9b7a-2e6f1d0c9a8b" \
  -H "Content-Type: application/json" \
  -d '{"url":"https://www.youtube.com/watch?v=dQw4w9WgXcQ"}'
```

```javascript
import { Transcript1 } from '@transcript1/sdk';

const t1 = new Transcript1();
const transcription = await t1.transcriptions.create('https://www.youtube.com/watch?v=dQw4w9WgXcQ', {
  idempotencyKey: '5f1c2b0e-8d4a-4c3e-9b7a-2e6f1d0c9a8b',
});
```

```python
import os
import requests

response = requests.post(
    "https://api.transcript1.com/v1/transcriptions",
    headers={"Authorization": f"Bearer {os.environ['TRANSCRIPT1_API_KEY']}", "Idempotency-Key": "5f1c2b0e-8d4a-4c3e-9b7a-2e6f1d0c9a8b"},
    json={"url": "https://www.youtube.com/watch?v=dQw4w9WgXcQ"},
)
print(response.json())
```

## Ошибки

- **Ошибка запроса:** API не принял вызов. Код и описание придут в HTTP-ответе.
- **Ошибка задачи:** API создал транскрибацию, но выполнить её не удалось. У задачи будет `status=failed`.

### Формат ошибки

При ошибке запроса к `/v1` API возвращает объект `error`. В нём всегда есть `code`, `message` и `retryable`.

- Выбирайте способ обработки по `code`.
- Текст `message` предназначен для пользователя. Не привязывайте к нему логику: формулировка может измениться.
- При `retryable=true` можно попробовать тот же запрос позже.

У некоторых ошибок есть дополнительные поля рядом с `retryable`:

| Поле | Код ошибки | Что содержит |
|---|---|---|
| `action_url` | `insufficient_minutes` | Ссылку для подключения тарифа или покупки минут. |
| `minutes_needed`, `minutes_remaining` | `insufficient_minutes` | Сколько минут требуется и сколько осталось. Если длительность ещё неизвестна, в первом поле будет `null`. |
| `supported_platforms` | `unsupported_platform` | Список допустимых платформ: `["youtube", "x", "tiktok", "instagram", "facebook", "bluesky", "twitch", "dailymotion", "pinterest", "linkedin", "snapchat"]`. |
| `missing_chunks` | `upload_incomplete` | Индексы недостающих частей файла. |
| `max_bytes` | `media_too_large` | Ваш лимит размера файла в байтах. |
| `params` | `invalid_request` | Ошибки в полях тела запроса или query-параметрах. Ключ объекта — имя поля, значение — описание проблемы. |

### Ошибки запроса

| HTTP-код | `code` | Повторить без изменений? | Причина и действие |
|---|---|---|---|
| 400, 422 | `invalid_request` | Нет | Не хватает параметра или поля, либо значение недопустимо. Например, нельзя сочетать `diarize` с `source: "captions"`, а `reuse_recent` — с `webhook_url`. Невалидный JSON даёт тот же код. |
| 422 | `invalid_url` | Нет | Проверьте ссылку и её соответствие `platform`. Подойдут YouTube, X, TikTok, Instagram, Facebook, Bluesky и другие платформы из раздела [«Источники и параметры»](https://transcript1.com/ru/docs/sources-and-options). |
| 422 | `unsupported_platform` | Нет | API не поддерживает указанное значение `platform`. |
| 422 | `unsupported_media` | Нет | Расширение загруженного файла не входит в список поддерживаемых. |
| 401 | `unauthorized` | Нет | Ключ или токен не передан, неверен, истёк или отозван. Для загрузки — токен неверен или истёк. |
| 403 | `insufficient_scope` | Нет | В OAuth-токене нет нужного разрешения: `transcriptions:read` или `transcriptions:write`. |
| 403 | `email_not_verified` | Нет | Для создания задачи сначала подтвердите почту. |
| 402 | `insufficient_minutes` | Нет | На балансе 0 минут или их не хватает на запись. |
| 402 | `no_active_plan` | Нет | Для покупки дополнительных минут нужен активный платный тариф. Ошибку возвращает только платёжный эндпоинт личного кабинета, не эндпоинты транскрибации. |
| 404 | `not_found` | Нет | Задача не найдена или принадлежит другой команде. |
| 409 | `upload_incomplete` | Нет | Загрузите недостающие части файла и снова вызовите завершение загрузки. |
| 409 | `invalid_state` | Нет | Задача больше не ждёт загрузки. Отправлять части или завершать её уже нельзя. |
| 409 | `idempotency_conflict` | Нет | Этот `Idempotency-Key` ранее передали с другим набором параметров. |
| 413 | `media_too_large` | Нет | Размер файла превышает ваш лимит — см. [«Загрузка файлов»](https://transcript1.com/ru/docs/uploads). |
| 413 | `invalid_request` | Нет | Тело JSON превышает 1 МБ. Для слишком большого файла используется другой код: `media_too_large`. |
| 429 | `rate_limited` | Да | Исчерпан лимит запросов в минуту. Число секунд до повтора указано в `Retry-After`. |
| 429 | `too_many_active_jobs` | Да | Достигнут лимит выполняющихся задач или открытых загрузок. Подождите столько секунд, сколько указано в `Retry-After`. |
| 500 | `internal_error` | Да | Ошибка на стороне transcript1. Попробуйте ещё раз чуть позже. |
| 503 | `service_unavailable` | Да | Сервис временно недоступен. Попробуйте ещё раз чуть позже. |

Если браузерный запрос использует cookie входа, проверяем также источник. Вызов с другого сайта вернёт `403 forbidden_origin`.

К API-запросам с заголовком `Authorization` эта проверка не относится.

В любом ответе `429` есть `Retry-After` — время ожидания в секундах. Значения лимитов приведены в разделе [«Тарифы и лимиты»](https://transcript1.com/ru/docs/billing-and-limits).

### Когда повторять запрос

- Автоматический повтор допустим при `retryable=true`: для `rate_limited`, `too_many_active_jobs`, `internal_error` и `service_unavailable`.
- Выдержите паузу из `Retry-After`. Если заголовка нет, увеличивайте интервал между попытками.
- Для повторного `POST /v1/transcriptions` сохраняйте прежний `Idempotency-Key`. Если первый запрос успел пройти, новая попытка не приведёт к повторному списанию.
- Остальные ошибки требуют исправления запроса. Отправлять его без изменений не стоит.

### Если транскрибация завершилась с ошибкой

Если у задачи `status=failed`, причину можно узнать из объекта `error` с полями `code` и `message`.

Ошибка может возникнуть уже после успешного HTTP-ответа. Проверяйте `error`, когда запрашиваете статус или получаете [вебхук](https://transcript1.com/ru/docs/api-reference#webhooks) `transcription.failed`.

| `error.code` | Что случилось | Что делать |
|---|---|---|
| `media_unavailable` | Видео удалено, не существует или недоступно. | Проверьте URL. Повтор без изменений не поможет. |
| `media_private` | Доступ к видео закрыт. | Нужен публичный пост. Для YouTube подойдёт также видео с доступом по ссылке. |
| `login_required` | Для просмотра нужен вход в аккаунт. | Не повторяйте: это постоянная ошибка, автоматических повторов нет. |
| `no_audio` | У видео нет звуковой дорожки. | Не повторяйте: это постоянная ошибка, автоматических повторов нет. |
| `age_restricted` | Просмотр ограничен по возрасту. | Вместо повторного запроса загрузите файл. |
| `live_stream` | Трансляция ещё идёт или не началась. | Попробуйте после её завершения. |
| `no_captions` | В режиме `captions` не нашлось подходящей дорожки субтитров. | Смените `source` на `"auto"` или `"stt"`. |
| `media_too_long` | Запись длиннее 5 часов — лимита распознавания речи. | Разделите запись. Повтор целиком не поможет. |
| `unsupported_media` | Не удалось прочитать файл или в нём нет аудиодорожки. | Отправьте файл в поддерживаемом формате. |
| `no_speech` | Речь не обнаружена. | Не повторяйте. |
| `unsupported_language` | Язык записи не поддерживается. | Укажите в `language` поддерживаемый код или `"auto"`. Без изменений не повторяйте. |
| `insufficient_minutes` | К моменту списания на балансе не хватило минут. | Пополните баланс и попробуйте снова. |
| `fetch_failed` | Несколько попыток скачать запись не удались. | Попробуйте ещё раз позже. |
| `transcription_failed` | Распознать речь не удалось даже после повторных попыток. | Попробуйте ещё раз позже. |

Если транскрибация завершилась с ошибкой или вы её отменили, платить не нужно. Уже списанные минуты вернём на баланс.

## Transcriptions

Create, read, list and delete transcriptions of video links and uploaded files.

### Create a transcription

`POST /v1/transcriptions`

Transcribes an uploaded file or a YouTube, X, TikTok, Instagram, Facebook, Bluesky, Twitch, Dailymotion, Pinterest, LinkedIn, Snapchat link. Social posts must be public; only the first video is used.

Twitch accepts clips and completed VODs; Pinterest accepts native video pins; LinkedIn accepts public video posts; Snapchat accepts Spotlight. New platforms require public recorded native media without supplied account cookies; no live streams or external embeds.

`platform` is optional and detected from the link. Captions are YouTube/X-only. All sources use the same per-minute price.

Returns `200` for a final result, `201` when awaiting an upload and `202` while processing. Pass `wait` to wait up to 60 seconds for a final status.

Pass `reuse_recent=true` with a platform URL to reuse a transcription of the same video and options from the last 24 hours. The response includes `reused: true`, with no additional charge. Short links may not be matched. An `Idempotency-Key` replay takes precedence.

#### Query

- `wait` (integer, optional, nullable, default 0): Seconds to wait for a final status before responding, up to 60. Defaults to 0.
- `reuse_recent` (string, optional, default false, one of `true`, `false`): For platform URLs only. Cannot be combined with `webhook_url`. Returns the team's most recent transcription of the same video with the same `source`, `language` and `diarize`. It must have been created in the last 24 hours and must not be `failed` or `canceled`. Reuses that transcription without creating or charging for a new one.

#### Headers

- `Idempotency-Key` (string, optional): Returns the original transcription when you repeat a request with the same key and parameters.

#### Body

- With `url`
  - `platform` (string, optional, one of `youtube`, `x`, `tiktok`, `instagram`, `facebook`, `bluesky`, `twitch`, `dailymotion`, `pinterest`, `linkedin`, `snapchat`): Optional; detected from the link. If supplied, must match the link.
  - `url` (string, required): YouTube, X, TikTok, Instagram, Facebook, Bluesky, Twitch, Dailymotion, Pinterest, LinkedIn, Snapchat video link. Social posts must be public; only the first video is used. New platforms support public recorded native video without supplied account cookies, not live streams or external embeds.
  - `source` (string, optional, one of `auto`, `captions`, `stt`): "auto" uses YouTube or X captions when available, otherwise speech-to-text. "captions" is YouTube/X-only. "stt" always uses speech-to-text.
  - `language` (string, optional)
  - `diarize` (boolean, optional)
  - `webhook_url` (string, uri, optional)
- With `upload`
  - `upload` (object, required)
    - `filename` (string, required)
    - `size` (integer, required)
    - `mime_type` (string, optional)
  - `source` (string, optional, one of `auto`, `stt`)
  - `language` (string, optional)
  - `diarize` (boolean, optional)
  - `webhook_url` (string, uri, optional)
- multipart/form-data
  - `file` (string, binary, required)
  - `source` (string, optional, one of `auto`, `stt`)
  - `language` (string, optional)
  - `diarize` (boolean, optional)
  - `webhook_url` (string, uri, optional)

#### Returns

- 200 OK: The transcription reached a final status
- 201 Created: The transcription is awaiting a chunked upload. `upload` describes where to send each chunk.
- 202 Accepted: The transcription is processing
- 400 Bad Request: The JSON request body is malformed
- 401 Unauthorized: Missing or invalid credential
- 402 Payment Required: Not enough minutes. Applies to every request body format.
- 403 Forbidden: Insufficient scope, unverified email, cross-site request or a single-member team plan
- 409 Conflict: `Idempotency-Key` was reused with different parameters.
- 413 Content Too Large: The upload or the JSON request body is too large
- 422 Unprocessable Content: Invalid request, URL, platform or file type
- 429 Too Many Requests: Too many requests or too many active transcriptions. Wait for the number of seconds in `Retry-After`.

### Get a transcription

`GET /v1/transcriptions/{id}`

Returns the transcription object. Completed transcriptions include the transcript. Use `format` to render it as text, SRT or WebVTT.

If you request a rendered format before completion, the response is JSON. It returns `202` while processing or `200` if the transcription failed or was canceled.

With `include_deleted=true`, a deleted transcription is returned as a record without a transcript. For deleted records, `wait` is ignored and rendered formats return `404`.

#### Path

- `id` (string, required)

#### Query

- `wait` (integer, optional, nullable, default 0): Seconds to wait for a final status before responding, up to 60. Defaults to 0.
- `format` (string, optional, default json, one of `json`, `text`, `srt`, `vtt`)
- `include` (string, optional, one of `words`)
- `timestamps` (string, optional, default false, one of `true`, `false`)
- `include_deleted` (string, optional, default false, one of `true`, `false`): Also returns deleted transcriptions as read-only records without a transcript. Their `deleted_at` is set. Defaults to `false`.

#### Returns

- 200 OK: The transcription, or the rendered transcript
- 202 Accepted: A rendered format was requested while the transcription is still processing
- 401 Unauthorized: Missing or invalid credential
- 403 Forbidden: Insufficient scope or a single-member team plan
- 404 Not Found: Transcription not found
- 422 Unprocessable Content: Invalid query parameters
- 429 Too Many Requests: Too many requests. Wait for the number of seconds in `Retry-After`.

## Uploads

Send a large file in chunks. Start with Create a transcription using an `upload` body. Send each chunk, then complete the upload.

### Upload one chunk

`PUT /v1/transcriptions/{id}/upload/chunks/{index}`

Sends one chunk of a chunked upload as `application/octet-stream`.

Authenticate with the `X-Upload-Token` from the create response. This endpoint does not use a bearer credential.

The body must match the planned chunk size exactly. Sending a chunk again replaces it.

#### Path

- `id` (string, required)
- `index` (integer, optional, nullable): Zero-based chunk number from the upload plan

#### Headers

- `X-Upload-Token` (string, required)

#### Body

- `(raw body)` (string, binary, required)

#### Returns

- 200 OK: The chunk was stored
- 401 Unauthorized: Missing, invalid or expired upload token
- 404 Not Found: Transcription not found
- 409 Conflict: The transcription is no longer awaiting an upload
- 422 Unprocessable Content: Index outside the chunk plan or wrong body size

### Complete a chunked upload

`POST /v1/transcriptions/{id}/upload/complete`

Checks that every planned chunk arrived with the planned size. Then assembles the file and queues the transcription.

#### Path

- `id` (string, required)

#### Returns

- 202 Accepted: The transcription is queued
- 401 Unauthorized: Missing or invalid credential
- 402 Payment Required: Not enough minutes to queue the transcription. The upload stays awaiting completion.
- 403 Forbidden: Insufficient scope, cross-site request or a single-member team plan
- 404 Not Found: Transcription or upload not found
- 409 Conflict: `upload_incomplete` means chunks are missing. `missing_chunks` lists them. `invalid_state` means the transcription is not awaiting an upload.
- 429 Too Many Requests: Too many requests or too many active transcriptions. Wait for the number of seconds in `Retry-After`.

## Вебхуки

Укажите `webhook_url`, когда создаёте задачу. После успешного завершения или ошибки transcript1 отправит на этот адрес подписанный `POST`.

Настроить вебхук можно только через REST API. Инструменты [MCP-сервера](https://transcript1.com/ru/docs/mcp) не принимают этот параметр.

### Куда отправлять уведомления

В `POST /v1/transcriptions` передайте `webhook_url`:

- Если отправляете ссылку на видео или создаёте загрузку по частям — в теле JSON.
- Если загружаете файл одним запросом — в поле формы.

Требования к ссылке:

- протокол HTTPS;
- без логина и пароля в URL;
- хост разрешается в публичный адрес.

Частный, loopback, link-local или другой непубличный адрес даст `422 invalid_request`. Проверяем адрес и при создании задачи, и перед каждой отправкой вебхука.

В одном запросе нельзя передавать `webhook_url` и `reuse_recent=true`.

### События

| `type` | Что произошло |
|---|---|
| `transcription.completed` | Транскрипт готов, статус задачи — `completed`. |
| `transcription.failed` | Задача завершилась с `failed`. Код и описание ошибки находятся в `data.error`, в полях `code` и `message`. |

Если вы отменили транскрибацию, уведомления не будет.

### Тело запроса

Уведомление приходит в формате JSON:

- В `created_at` записано время создания события.
- В `data` находится объект транскрибации, но без поля `transcript`.

Возьмите `id` из `data` и запросите готовый текст через `GET /v1/transcriptions/:id`.

В запросе будут следующие заголовки:

- `Content-Type: application/json`
- `User-Agent: transcript1-webhooks/1.0`
- `X-Transcript1-Signature` — подпись для проверки подлинности запроса.

### Как проверить подпись

С каждым вебхуком передаём `X-Transcript1-Signature` в формате `t=<unix seconds>,v1=<hex digest>`.

- `t` — Unix-время подписания запроса, в секундах.
- `v1` — шестнадцатеричный HMAC-SHA256 для строки `"<t>.<raw body>"`. Соберите её из `t`, точки и исходного тела запроса. Ключ — секрет подписи целиком, с префиксом `whsec_`.

Вычисляйте подпись по исходным байтам, до разбора JSON. После разбора и обратной сериализации могут измениться пробелы или порядок ключей — подпись уже не совпадёт.

- Используйте сравнение за постоянное время.
- Проверяйте расхождение `t` с текущим временем и отклоняйте запрос при слишком большой разнице. В примерах допустимы 5 минут.
- В Express сначала прочитайте тело как текст, без разбора JSON.
- В Flask получите исходное тело через `request.get_data(as_text=True)` и передайте его в `raw_body`.

### Где взять секрет подписи

У команды один секрет для вебхуков всех её транскрибаций. Он начинается с `whsec_`.

Посмотреть или заменить его можно на странице [«Webhooks»](https://transcript1.com/dashboard/webhooks).

После замены старый секрет сразу перестаёт действовать. Все последующие вебхуки подписываем новым.

### Доставка и повторные попытки

- Верните любой код `2xx`, чтобы подтвердить получение вебхука.
- Другой статус, ошибка соединения или отсутствие ответа за 10 секунд означают, что попытка не удалась.
- При неудаче повторяем отправку с растущими паузами: 2, 4, 8, 16 и 32 минуты. Всего будет не больше 6 попыток, последняя — примерно через час после первой.
- Сразу указывайте конечный URL. transcript1 не следует редиректам: ответ `3xx` тоже считается неудачей.
- Один вебхук может прийти несколько раз — например, если ваш сервер ответил уже после таймаута. Отсеивайте дубликаты по сочетанию `data.id` и `type`.

```javascript
import { Buffer } from 'node:buffer';
import crypto from 'node:crypto';

// header: X-Transcript1-Signature, rawBody: the request body exactly as received,
// secret: your full signing secret including the whsec_ prefix.
export const verifySignature = (secret, header, rawBody, nowSeconds = Math.floor(Date.now() / 1000)) => {
  const fields = Object.fromEntries(header.split(',').map(part => part.trim().split('=')));
  const t = Number(fields.t);

  if (!Number.isInteger(t) || !fields.v1 || Math.abs(nowSeconds - t) > 300) {
    return false;
  }

  const expected = crypto.createHmac('sha256', secret).update(`${t}.${rawBody}`).digest('hex');

  return fields.v1.length === expected.length
    && crypto.timingSafeEqual(Buffer.from(fields.v1), Buffer.from(expected));
};
```

```python
import hashlib
import hmac
import time


def verify_signature(secret, header, raw_body, now=None):
    # header: the X-Transcript1-Signature header, raw_body: the request body exactly as received,
    # secret: your full signing secret including the whsec_ prefix.
    fields = dict(part.strip().split("=", 1) for part in header.split(",") if "=" in part)
    try:
        t = int(fields["t"])
    except (KeyError, ValueError):
        return False

    now = int(time.time()) if now is None else now
    if abs(now - t) > 300:
        return False

    expected = hmac.new(secret.encode(), f"{t}.{raw_body}".encode(), hashlib.sha256).hexdigest()
    return hmac.compare_digest(fields.get("v1", ""), expected)
```
