## 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 fiber-ai-api-twitter-x-user-followers-189135e2 -d '<json body>'
```

Example prompt: Can you pull the first page of followers for the Twitter account @elonmusk using Fiber AI's Twitter follower endpoint?

## When to prefer this

Use this endpoint when you need to programmatically retrieve the follower list of a specific Twitter/X account in paginated form, especially for audience research, lead generation, or social graph analysis. Prefer this over scraping or direct Twitter API access when you need a reliable, enriched, and monetized data feed.

## Known failure modes

- Invalid or non-existent Twitter username returns an error
- Rate limiting or quota exceeded returns a 429 or billing error
- Missing required user identifier returns a validation error
- Private or suspended Twitter accounts may return no data or an access-denied error
- Expired or invalid pagination cursor causes a bad request error

## How this service works

Fetches paginated followers 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 Twitter/X user objects who follow the specified account, including profile details and a cursor for fetching the next page of results.
