## API base URL and authentication

- **API origin (from OpenAPI `servers`):** `https://api.socialfetch.dev`
- **Authentication:** send `x-api-key: sfk_...` on `/v1/**` and `/v2/**` 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).
- **OpenAPI JSON:** [https://www.socialfetch.dev/openapi.json](https://www.socialfetch.dev/openapi.json)

- [Credits](https://www.socialfetch.dev/docs/credits.mdx) — metering, `402`, and planning batch jobs.
- Outcome semantics such as `found`, `not_found`, and `private` are documented in [Errors](https://www.socialfetch.dev/docs/errors.mdx) and on operation pages when present in the OpenAPI contract.

## Markdown docs convention

- Every docs page has a markdown twin: append **`.mdx`** to the docs pathname (for example `/docs/quickstart` → `/docs/quickstart.mdx`).
- Agents that send `Accept: text/markdown` on `/docs/**` HTML URLs may receive markdown directly (same URL, `Vary: Accept`).
- Published blog posts use the same convention: `/blog/{slug}` → `/blog/{slug}.mdx`, or `Accept: text/markdown` on the HTML URL (`Vary: Accept`).

## Summary

List reactions on a LinkedIn activity.

**Tags:** `LinkedIn`

- **Method:** GET
- **Path:** `/v2/linkedin/activities/{activityId}/reactions`
- **operationId:** `linkedin.live.activity.reactions.v2`
- **Base URL:** `https://api.socialfetch.dev`

## Capability summary

- **SDK mapping:** `client.linkedin.getActivityReactions({ activityId: "urn:li:activity:7238942337892753408" })`
- **Pagination:** cursor via `cursor`, next cursor: `data.page.nextCursor`, has more: `data.page.hasMore`
- **Business outcome field:** `data.lookupStatus` with values `found`, `not_found`

## Credits

- **Base:** 3 credits per successful lookup.
- **Maximum on success (200):** 3 credits.
- **Normalization failure (502):** 0 credits charged.
- **Authoritative field:** `meta.creditsCharged`.

## Authentication

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

## Parameters

### `activityId` (path)

- **Required:** yes
- **Constraints:** type `string`
- **Description:** LinkedIn activity ID.

### `start` (query)

## 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**: Request could not be completed. **Retry:** Fix the request; retrying the same invalid payload will not help.
- **401**: Request could not be completed. **Retry:** Fix the API key first; retrying without changes will not help.
- **402**: Request could not be completed. **Retry:** Do not retry without resolving billing/credits (retrying the same request will not help).
- **413**: Response exceeds 4,000,000 bytes. No charge; request fewer URLs.
- **429**: Request could not be completed.
- **500**: Request could not be completed.
- **502**: Request could not be completed. **Retry:** May be transient; a few retries with backoff are reasonable.
- **503**: Request could not be completed. **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.linkedin.getActivityReactions({
  activityId: "7506405584091541505",
});

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

### Node.js

```javascript
const response = await fetch(
  "https://api.socialfetch.dev/v2/linkedin/activities/7506405584091541505/reactions",
  {
    headers: {
      "x-api-key": "YOUR_API_KEY"
    }
  }
);

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

### cURL

```bash
curl "https://api.socialfetch.dev/v2/linkedin/activities/7506405584091541505/reactions" \
  -H "x-api-key: YOUR_API_KEY"
```

### Python

```python
import requests

response = requests.get(
    "https://api.socialfetch.dev/v2/linkedin/activities/7506405584091541505/reactions",
    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/v2/linkedin/activities/abc123/reactions");
  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();
}
```
