## 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 twitter-x-user-mentions-fetcher-45c8bb57 -d '<json body>'
```

Example prompt: Can you pull all the recent mentions of the Twitter account @elonmusk so I can see what people are saying about them?

## When to prefer this

Use this endpoint when you need to retrieve mentions of a specific Twitter/X user handle, especially for brand monitoring, influencer tracking, or social listening workflows. It is particularly cost-effective for paginated retrieval since subsequent pages using parentRequestId are billed at $0. Prefer this over general Twitter search when the target is a specific user's mentions rather than keyword-based discovery.

## Known failure modes

- Invalid or non-existent Twitter handle returns empty results or error
- Missing handle parameter causes request failure
- Expired or invalid pagination cursor breaks continuation
- Changing non-pagination parameters while passing parentRequestId starts a new billable request
- Rate limiting or Twitter API restrictions may limit result freshness or volume

## How this service works

Fetches paginated mentions of a Twitter/X user. Pagination billing: call the first page normally and save billing.requestId from the Orthogonal /v1/run response. For later page, offset, or cursor calls on the same logical search, pass parentRequestId with unchanged non-pagination parameters. Valid continuation calls still get their own request IDs and quoted price, but are charged 0. Changing filters starts a new billable request.

## Output

Returns a paginated list of tweets that mention the specified Twitter/X handle, including tweet content, author info, timestamps, and engagement metadata. Includes a pagination cursor for fetching subsequent pages at no additional charge when using parentRequestId.
