## 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 readx-x-twitter-json-api-per-call-no-keys-c49cc8a1
```

Example prompt: Pull the recent tweets and profile info for the X user @elonmusk — I want their bio, follower count, and latest 10 posts.

## When to prefer this

Choose ReadX when you need read-only X/Twitter data — profiles, timelines, or search — without setting up Twitter developer credentials. Ideal for agents needing occasional, pay-as-you-go Twitter lookups using x402 USDC micropayments on Base or Solana, where API key management is impractical.

## Known failure modes

- Invalid or non-existent username returns empty data or error code
- Insufficient USDC balance causes payment failure and 402 response
- Rate limits or X API restrictions may cause upstream errors
- Malformed endpoint name in URL path returns 404 or error
- Private/suspended accounts return no data
