## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability readx-mentions-feed-62d8a3f3
```

Example prompt: Pull all the recent tweets mentioning @elonmusk from ReadX — paginate through all of them until there are no more results.

## When to prefer this

Use this endpoint when you need to retrieve tweets that mention a specific X/Twitter user, especially for monitoring brand mentions, tracking public discourse about an account, or paginating through a full mention history. Prefer this over a general search endpoint when you want mentions targeted specifically at one user handle rather than keyword-based results.

## Known failure modes

- Invalid or non-existent username returns an empty result or 404 error
- Username fails pattern validation (non-alphanumeric/underscore characters) returns a 400 bad request
- Invalid cursor value causes a pagination error
- Payment not processed results in 402 Payment Required
- Rate limiting or upstream X API unavailability returns a 429 or 503 error

## How this service works

Tweets that mention a user (paginate with cursor until has_more is false). Example: GET /api/jack/mentions

## Output

A JSON response containing a list of tweet objects that mention the specified user, along with a pagination object including a bottom cursor and a has_more boolean to continue fetching subsequent pages.
