> **For coding agents and LLMs:** This is one page from the Social Fetch docs (markdown export). The sections below mirror the orientation block in [`/llms.txt`](https://www.socialfetch.dev/llms.txt); use [`/llms.json`](https://www.socialfetch.dev/llms.json) when you need a structured operation inventory. The catalog covers documented operations with on-site reference pages.

## This page

- **On-site (HTML):** [https://www.socialfetch.dev/docs/api/v1/linkedin/posts/get](https://www.socialfetch.dev/docs/api/v1/linkedin/posts/get)
- **Markdown (.mdx) URL:** [https://www.socialfetch.dev/docs/api/v1/linkedin/posts/get.mdx](https://www.socialfetch.dev/docs/api/v1/linkedin/posts/get.mdx)

## 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).

## Recommended docs entrypoints (this site)

- [Documentation overview](https://www.socialfetch.dev/docs.mdx) — top-level orientation (markdown).
- [Quickstart](https://www.socialfetch.dev/docs/quickstart.mdx) — authenticate with `x-api-key`, validate auth with `whoami`, and understand the JSON envelope.
- [SDK](https://www.socialfetch.dev/docs/sdk.mdx) — official TypeScript SDK guide, including `SocialFetchClient`, `Result`, and `unwrap()`.
- [SDK reference](https://www.socialfetch.dev/docs/sdk-reference.mdx) — exhaustive SDK method inventory and route mapping for agents, tooling, and power users.
- [Choose the right endpoint](https://www.socialfetch.dev/docs/choose-endpoint.mdx) — task-oriented route selection for smoke tests, profiles, list endpoints, and single-item lookups.
- [Capability matrix](https://www.socialfetch.dev/docs/capability-matrix.mdx) — fast comparison of identifiers, pagination, outcomes, media download, and SDK coverage.
- [`/llms.json`](https://www.socialfetch.dev/llms.json) — structured machine-readable operation inventory with parameter names, pagination, outcomes, credits, and SDK mapping.
- [API reference hub](https://www.socialfetch.dev/docs/api.mdx) — human-friendly index of operations with links into generated pages.
- [Errors](https://www.socialfetch.dev/docs/errors.mdx) — shared error envelope and HTTP status guidance.
- [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`).

### 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 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.linkedin.getPost({
  url: "https://www.linkedin.com/posts/sundarpichai_small-businesses-are-the-engine-of-the-american-share-7449849038398697472-iNtG",
});

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/linkedin/posts?url=https://www.linkedin.com/posts/sundarpichai_small-businesses-are-the-engine-of-the-american-share-7449849038398697472-iNtG",
  {
    headers: {
      "x-api-key": "YOUR_API_KEY",
    }
  }
);

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

### cURL

```bash
curl "https://api.socialfetch.dev/v1/linkedin/posts?url=https://www.linkedin.com/posts/sundarpichai_small-businesses-are-the-engine-of-the-american-share-7449849038398697472-iNtG" \
  -H "x-api-key: YOUR_API_KEY"
```

### Python

```python
import requests

response = requests.get(
