> **For coding agents and LLMs:** This is one page from the Social Fetch docs (markdown export). For curated orientation and workflow guidance, start with [`/llms.txt`](https://www.socialfetch.dev/llms.txt); for agent onboarding and crawl rules, use [`/agents.txt`](https://www.socialfetch.dev/agents.txt); for the full endpoint list with links to pages like this one, use [`/llms-endpoints.txt`](https://www.socialfetch.dev/llms-endpoints.txt); for one platform's parameters and curls, use [`/llms-{platform}.txt`](https://www.socialfetch.dev/llms-tiktok.txt); use [`/llms.json`](https://www.socialfetch.dev/llms.json) when you need structured JSON for tool registration.

- **Markdown (.mdx) URL:** <https://www.socialfetch.dev/docs/api/v1/mastodon/posts/context/get.mdx>

## 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>

## Recommended docs entrypoints (this site)

- [Capability matrix](https://www.socialfetch.dev/docs/capability-matrix.mdx) — every operation with identifiers, pagination, outcomes, media download, credits, and its SDK method. Generated from OpenAPI, so use it for route selection instead of scanning individual pages.
- [Recipes](https://www.socialfetch.dev/docs/recipes.mdx) — copyable workflows (brand monitoring, transcripts, Ad Library, creator scoring, Reddit research) with credit callouts and SDK examples.

- [`/llms-endpoints.txt`](https://www.socialfetch.dev/llms-endpoints.txt) — every documented operation with a direct link to that route's agent-readable markdown page (prefer this over parsing OpenAPI).
- [`/llms-{platform}.txt`](https://www.socialfetch.dev/llms-tiktok.txt) — per-platform endpoint files generated from OpenAPI (parameters, credits, curls).
- [`/agents.txt`](https://www.socialfetch.dev/agents.txt) — agent crawl/onboarding file with capabilities, auth rules, and allowlist.
- [`/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`).
- Published blog posts use the same convention: `/blog/{slug}` → `/blog/{slug}.mdx`, or `Accept: text/markdown` on the HTML URL (`Vary: Accept`).

# Get Mastodon post reply tree (https://www.socialfetch.dev/docs/api/v1/mastodon/posts/context/get)

## Summary

Get the posts a Mastodon post replies to and the replies under it.

**Tags:** `Mastodon`

## HTTP

- **Method:** GET
- **Path:** `/v1/mastodon/posts/context`
- **Base URL:** `https://api.socialfetch.dev`

## Capability summary

- **SDK mapping:** `client.mastodon.getPostContext({ url: "https://mastodon.social/@Gargron/117555039933723776" })`
- **Accepted identifiers:** `url` (query)
- **Pagination:** none
- **Business outcome field:** `data.lookupStatus` with values `found`, `not_found`, `restricted`, `unsupported`, `not_compatible`

## Credits

- **Base:** 1 credit per successful lookup.
- **Maximum on success (200):** 1 credit.
- **Failed requests (`lookup_failed`, `503`):** not charged.
- **Authoritative field:** `meta.creditsCharged`.

## Authentication

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

## Parameters

### `url` (query)

- **Required:** yes
- **Constraints:** type `string`
- **Description:** Public URL of a post, e.g. `https://mastodon.social/@Gargron/117555039933723776`. The server in the URL is the server asked, because post ids belong to a server.

## Responses (status codes)

### 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. **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.mastodon.getPostContext({
  url: "https://mastodon.social/@Gargron/117555039933723776",
});

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/mastodon/posts/context?url=https://mastodon.social/@Gargron/117555039933723776",
  {
    headers: {
      "x-api-key": "YOUR_API_KEY"
    }
  }
);

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

### cURL

```bash
curl "https://api.socialfetch.dev/v1/mastodon/posts/context?url=https://mastodon.social/@Gargron/117555039933723776" \
  -H "x-api-key: YOUR_API_KEY"
```

### Python

```python
import requests

response = requests.get(
    "https://api.socialfetch.dev/v1/mastodon/posts/context?url=https://mastodon.social/@Gargron/117555039933723776",
    headers={"x-api-key": "YOUR_API_KEY"},
)
data = response.json()
print(data)
```
