## API base URL and authentication

- **API origin (from OpenAPI `servers`):** `https://api.socialfetch.dev`
- **Authentication:** send `x-api-key: sfk_...` on `/v1/**` routes unless the operation is explicitly anonymous (check OpenAPI `security`, the [API reference hub](https://www.socialfetch.dev/docs/api.mdx), [`/llms.txt`](https://www.socialfetch.dev/llms.txt), or [`/llms.json`](https://www.socialfetch.dev/llms.json) for each route).

# List Instagram audio Reels (https://www.socialfetch.dev/docs/api/v1/instagram/audio/audioid/reels/get)

## Summary

List Instagram Reels that use a specific audio track, with track metadata, tagged users, and coauthors when Instagram exposes them.

**Tags:** `Instagram`

## HTTP

- **Method:** GET
- **Path:** `/v1/instagram/audio/{audioId}/reels`
- **Base URL:** `https://api.socialfetch.dev`

## Capability summary

- **SDK mapping:** `client.instagram.listAudioReels({ audioId, cursor? })`
- **Pagination:** cursor via `cursor`, next cursor: `data.page.nextCursor`, has more: `data.page.hasMore`

## Agent notes

- **Empty results:** An empty `data.reels` array can mean no public Reels use this audio, or other cases—there is no `lookupStatus` field on this route.

## Credits

- **Base:** 1 credit per successful lookup.
- **Maximum on success (200):** 1 credit.
- **Normalization failure (502):** 1 credit charged.
- **Authoritative field:** `meta.creditsCharged`.

## Authentication

- **`x-api-key`**: API key (`sfk_...`)

## Parameters

### `audioId` (path)

- **Required:** yes
- **Constraints:** type `string`; minLength: 1
- **Description:** Instagram audio id whose Reels should be listed.

### `cursor` (query)

- **Required:** no
- **Constraints:** type `string`; minLength: 1
- **Description:** Pagination cursor returned by a previous response.

## Pagination

This endpoint uses **cursor-based pagination** via the `cursor` query parameter.

- Read **hasMore** from `data.page.hasMore`.
- When that value is `true`, read **nextCursor** from `data.page.nextCursor` and pass it as the `cursor` query parameter on the **next** request (URL-encode when building a query string).
- Omit `cursor` on the **first** request.
- Stop when **hasMore** is `false` or **nextCursor** is null (end of list).

## Responses (status codes)

- **200**: Reels for the requested Instagram audio.
- **400**: Invalid audio id or bad request
- **401**: Missing or invalid API key
- **402**: Insufficient credits
- **500**: Unexpected or billing error
- **502**: Lookup could not be completed from the response (unexpected or invalid data).
- **503**: Service temporarily unavailable; safe to retry with backoff.

### Example JSON (empty)

```json
{
  "data": {
    "audioId": "999999999999999999",
    "reels": [],
    "page": {
      "hasMore": false,
      "nextCursor": null
    }
  },
  "meta": {
    "requestId": "req_01example_audio_reels_empty",
    "creditsCharged": 1,
    "version": "v1"
  }
}
```

### Machine-readable error codes

When an error JSON body is returned, it may include one of these `error.code` values (derived from the OpenAPI schemas for this operation; additional codes may exist at runtime):

- `bad_request`

## Error handling & retries

Interpret HTTP status codes using the descriptions below. Do not assume a JSON body unless the OpenAPI schema defines one for that status.

- **400**: Invalid audio id or bad request **Retry:** Fix the request; retrying the same invalid payload will not help.
- **401**: Missing or invalid API key **Retry:** Fix the API key first; retrying without changes will not help.
- **402**: Insufficient credits **Retry:** Do not retry without resolving billing/credits (retrying the same request will not help).
- **500**: Unexpected or billing error
- **502**: Lookup could not be completed from the response (unexpected or invalid data). **Retry:** May be transient; a few retries with backoff are reasonable.
- **503**: Service temporarily unavailable; safe to retry with backoff. **Retry:** Usually safe to retry with exponential backoff and jitter.

### Suggested client defaults

- Send the API key using the `x-api-key` header on every request.
- On `503` (and sometimes `502`), retry with backoff; cap retries and surface a clear error to the user.
- On `402`, surface an actionable billing message rather than blind retries.

## Examples

### TypeScript SDK

```typescript
import { SocialFetchClient } from "@socialfetch/sdk";

const client = new SocialFetchClient({
  apiKey: process.env.SOCIALFETCH_API_KEY!,
});

const result = await client.instagram.listAudioReels({
  audioId: "1392969992841787",
});

if (!result.ok) {
  console.error(result.error);
} else {
  console.log(result.value.data);
}
```

### Node.js

```javascript
const response = await fetch(
  "https://api.socialfetch.dev/v1/instagram/audio/1392969992841787/reels",
  {
    headers: {
      "x-api-key": "YOUR_API_KEY"
    }
  }
);

const data = await response.json();
console.log(data);
```

### cURL

```bash
curl "https://api.socialfetch.dev/v1/instagram/audio/1392969992841787/reels" \
  -H "x-api-key: YOUR_API_KEY"
```

### Python

```python
import requests

response = requests.get(
    "https://api.socialfetch.dev/v1/instagram/audio/1392969992841787/reels",
    headers={"x-api-key": "YOUR_API_KEY"},
)
data = response.json()
print(data)
```

### Example: next page (pagination)

After a successful response, if pagination is not finished, request the next page using `cursor` (URL-encode when composing the query string):

```javascript
const previous = await response.json();
const nextCursor = previous?.data?.page?.nextCursor;
const hasMore = previous?.data?.page?.hasMore;
if (!hasMore || nextCursor == null) {
  // no more pages
} else {
  const nextUrl = new URL("https://api.socialfetch.dev/v1/instagram/audio/abc123/reels");
  nextUrl.searchParams.set("cursor", nextCursor);
  // optionally preserve sort: nextUrl.searchParams.set("sortBy", "latest");
  const nextResponse = await fetch(nextUrl.toString(), {
    headers: { "x-api-key": "YOUR_API_KEY" },
  });
  const nextData = await nextResponse.json();
}
```
