## 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-following-list-0ab1d44a -d '<json body>'
```

Example prompt: Can you pull the full list of accounts that @elonmusk is following on Twitter/X? Start from the beginning and page through all results.

## When to prefer this

Use this endpoint when you need to retrieve the accounts a specific Twitter/X user follows, especially when you need to paginate through large following lists efficiently. The parentRequestId chaining makes bulk following data retrieval cost-effective. Prefer this over manual Twitter API access when you want a simple pay-per-call interface without managing OAuth credentials.

## Known failure modes

- Invalid or non-existent Twitter handle returns an error or empty result
- Missing required 'handle' parameter causes a validation error
- Expired or invalid pagination cursor results in a failed continuation request
- Rate limiting or Twitter API restrictions may cause temporary unavailability
- Changing non-pagination parameters while passing parentRequestId starts a new billable request

## How this service works

Fetches paginated list of accounts a Twitter/X user follows. 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 accounts that the specified handle follows, including user profile information for each followed account and a pagination cursor for retrieving subsequent pages. Continued pagination pages after the first are billed at $0 when parentRequestId is passed correctly.
