## Parameters

| Name | In | Type | Required | Default | Constraints | Description |
|---|---|---|---|---|---|---|
| `source_type` | query | `string` | no | – | – | Only transcripts from this source. Allowed values: `youtube`, `upload`. |
| `archived` | query | `string` | no | `false` | – | Return active (`false`), archived (`true`) or all (`all`) items. Allowed values: `false`, `true`, `all`. |
| `added_after` | query | `string` | no | – | ≤ 64 characters | Only items added after this moment (exclusive). RFC 3339 date or date-time. Compared in milliseconds, like the timestamps in responses, so passing back a returned timestamp never returns that same item again. |
| `added_before` | query | `string` | no | – | ≤ 64 characters | Only items added before this moment (exclusive). RFC 3339 date or date-time. Compared in milliseconds, like the timestamps in responses, so passing back a returned timestamp never returns that same item again. |
| `q` | query | `string` | no | – | ≤ 200 characters | Search in the title. |
| `order` | query | `string` | no | `desc` | – | Sort direction. Allowed values: `desc`, `asc`. |
| `limit` | query | `integer` | no | `20` | 1–100; format: int32 | Page size, from 1 to 100. Default 20. Follow `has_more`, not the page size. |
| `cursor` | query | `string` | no | – | ≤ 1024 characters | Opaque cursor from `next_cursor` of the previous page. Cursors are tied to the user, route, sort order and filters. |

## Response

### 200

A page of library transcripts, sorted by `added_at`.

- `RateLimit`: The most restrictive policy that applied: `"name";r=<requests left>;t=<seconds>`, where `t` is the number of seconds until one more request is allowed (0 when the quota is full). Absent when no rate limiter ran for the request.
- `RateLimit-Policy`: The rate-limit policies that applied to the request, one `"name";q=<burst>;w=<seconds>` item per policy, for example `"read";q=10;w=2, "account";q=20;w=2`: `q` is the burst quota and `w` the seconds in which an empty quota refills. Sent on every authenticated response; absent when no rate limiter ran for the request, for example when it was rejected before the key was checked.
- `Request-Id`: ID of this request (`req_` prefix), the same as `request_id` in an error body. It is also sent as `X-Request-ID`. Quote it when you contact support.
- `X-Client-Request-Id`: Your own `X-Client-Request-Id` request header, echoed back. It is sent only when the value you sent has 1-128 characters from A-Z a-z 0-9 . _ : -.
- `X-RateLimit-Limit`: Burst quota of the most restrictive policy (`q` in `RateLimit-Policy`). Absent when no rate limiter ran.
- `X-RateLimit-Remaining`: Requests left in the most restrictive policy (`r` in `RateLimit`). Absent when no rate limiter ran.
- `X-RateLimit-Reset`: Seconds until one more request is allowed in the most restrictive policy (`t` in `RateLimit`; 0 when the quota is full). It is a number of seconds, not a timestamp. Absent when no rate limiter ran.

## Errors

This endpoint can return these errors. Every code is described in the error catalog.

| HTTP | Code | Meaning | Retry? |
|---|---|---|---|
| 400 | [`invalid_parameter`](https://diko.app/en/api-docs/errors.md#invalid_parameter) | A path, query or body parameter has an invalid value, a required field is missing or a field is unknown (unknown fields are rejected). `error.param` names the parameter. | no |
| 400 | [`invalid_cursor`](https://diko.app/en/api-docs/errors.md#invalid_cursor) | The `cursor` is corrupted or was issued for another user, route, sort order or set of filters. | no |
| 401 | [`missing_api_key`](https://diko.app/en/api-docs/errors.md#missing_api_key) | The request has no `Authorization` header. | no |
| 401 | [`invalid_api_key`](https://diko.app/en/api-docs/errors.md#invalid_api_key) | The header is unusable (a scheme other than `Bearer`, an empty key or more than one `Authorization` header) or the key is unknown or malformed (wrong structure or checksum). The response is identical in all these cases. | no |
| 401 | [`api_key_expired`](https://diko.app/en/api-docs/errors.md#api_key_expired) | The key has expired. | no |
| 401 | [`api_key_revoked`](https://diko.app/en/api-docs/errors.md#api_key_revoked) | The key was revoked: manually, after a rotation grace period ended, because of a leak or because the account was disabled. | no |
| 401 | [`api_key_disabled`](https://diko.app/en/api-docs/errors.md#api_key_disabled) | The key is temporarily disabled. | no |

| 403 | [`insufficient_scope`](https://diko.app/en/api-docs/errors.md#insufficient_scope) | The key lacks the scope this endpoint needs. `error.details` contains `required_scopes` and `granted_scopes`. | no |
| 429 | [`rate_limit_exceeded`](https://diko.app/en/api-docs/errors.md#rate_limit_exceeded) | A rate-limit policy was exceeded. `error.details.policy` names it. | yes, after Retry-After |
