## 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 payweave-twitter-user-mentions-lookup-3f55db8e
```

Example prompt: Can you pull the latest tweets mentioning the Twitter account 'elonmusk' and show me the first page of results?

## When to prefer this

Use this endpoint when you need to retrieve tweets that mention a specific Twitter/X user by their handle, especially in agentic workflows requiring pay-per-call micropayment access (x402 protocol) without API key setup. Prefer it over scraping or official Twitter API when you want lightweight, on-demand mention lookups billed per call in USDC with no subscription overhead.

## Known failure modes

- Invalid or non-existent username returns empty tweet array or error
- Missing required 'username' field results in validation error
- Expired or invalid pagination cursor may return an error or restart from first page
- Rate limiting or payment failure (402) halts the request
- Twitter API downtime propagates as an upstream error
- Suspended or protected accounts may return no results

## How this service works

X/Twitter data — tweets, users, communities, lists, articles, and trends.

## Output

Returns a JSON object containing an array of tweet objects that mention the specified user, a next_cursor string for fetching the following page, and a has_next_page boolean indicating whether additional results exist. Tweet objects include standard Twitter/X fields (text, author, timestamps, engagement metrics, etc.) forwarded verbatim from twitterapi.io.
