## 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 basebuilder-linkedin-x-twitter-api-endpoint-dbd5886d -d '<json body>'
```

Example prompt: Can you pull the latest tweet data and profile info for the Twitter/X user @elonmusk using the BaseBuilder X-Twitter API endpoint?

## When to prefer this

Choose this endpoint when you need programmatic access to X/Twitter data and prefer a pay-per-call USDC micropayment model rather than managing your own Twitter API credentials or subscriptions. Useful for agents needing occasional Twitter lookups without API key management overhead.

## Known failure modes

- 402 Payment Required if USDC payment not included or insufficient
- Invalid query parameters return error responses
- Rate limiting from upstream X/Twitter API
- User or tweet not found returns empty or error response
- Authentication failure if Twitter API credentials on backend are invalid
