> **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.

## 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>

- 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`).

# List Lemmy user posts (https://www.socialfetch.dev/docs/api/v1/lemmy/user/posts/get)

## Summary

List Lemmy posts by one user, in the order asked for.

**Tags:** `Lemmy`

## HTTP

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

## Capability summary

- **SDK mapping:** `client.lemmy.listUserPosts({ instance: "lemmy.world", username: "dessalines@lemmy.ml", sort: "New" })`
- **Accepted identifiers:** `username` (query)
- **Pagination:** cursor via `cursor`, next cursor: `data.page.nextCursor`, has more: `data.page.hasMore`
- **Business outcome field:** `data.lookupStatus` with values `found`, `not_found`, `private`, `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

### `instance` (query)

- **Required:** yes
- **Constraints:** type `string`
- **Description:** The Lemmy instance, e.g. `lemmy.world`. A URL on the instance is also accepted. Ids and counts belong to this instance.

### `username` (query)

- **Required:** yes
- **Constraints:** type `string`
- **Description:** Username, e.g. `dessalines`, or `user@lemmy.ml` to resolve a user on another instance.

### `sort` (query)

- **Required:** no
- **Constraints:** type `string`; enum: New, Old, TopHour, TopSixHour, TopTwelveHour, TopDay, TopWeek, TopMonth, TopThreeMonths, TopSixMonths, TopNineMonths, TopYear
- **Description:** Order. Only `New`, `Old` and the time-window tops; `TopAll` and `Hot` are not offered.

### `page` (query)

- **Required:** no
- **Constraints:** type `integer`; minimum: 1; maximum: 100
- **Description:** Page number, 1 to 100. Default: 1. An instance refuses pages past 100. Lemmy pages by number over a live order, so new or re-ranked items can shift a row onto the next page. Remove repeats by `id`.

### `cursor` (query)

- **Required:** no
- **Constraints:** type `string`; minLength: 1; maxLength: 2048
- **Description:** Pass `page.nextCursor` from the previous response to get the next page. It only works with the same filters; do not send it with `page`.

### `limit` (query)

- **Required:** no
- **Constraints:** type `integer`; minimum: 1; maximum: 50
- **Description:** Rows per page, 1 to 50. Default: 10.

## 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**: Post list.
- **400**: Invalid request
- **401**: Missing or invalid API key
- **402**: Insufficient credits
- **500**: Unexpected or billing error
- **502**: Lookup could not be completed.
- **503**: Service temporarily unavailable; safe to retry with backoff.

## Response body (200)

Post list.

### 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.lemmy.listUserPosts({
  instance: "lemmy.world",
  username: "dessalines@lemmy.ml",
});

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/lemmy/user/posts?instance=lemmy.world&username=dessalines@lemmy.ml",
  {
    headers: {
      "x-api-key": "YOUR_API_KEY"
    }
  }
);

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

### cURL

```bash
curl "https://api.socialfetch.dev/v1/lemmy/user/posts?instance=lemmy.world&username=dessalines@lemmy.ml" \
  -H "x-api-key: YOUR_API_KEY"
```

### Python

```python
import requests

response = requests.get(
    "https://api.socialfetch.dev/v1/lemmy/user/posts?instance=lemmy.world&username=dessalines@lemmy.ml",
    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/lemmy/user/posts");
  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();
}
```
