## 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 ggwp-api-hub-x-checker-e9b4810e -d '<json body>'
```

Example prompt: Can you check whether the X account @elonmusk is active and pull up any available profile details for it?

## When to prefer this

Use this endpoint when you need a quick, pay-per-call check on an X (Twitter) account or post without committing to a subscription-based social media API. Particularly useful in agent workflows that need one-off verification of social handles on the Base chain via x402 micropayments.

## Known failure modes

- Account not found — returns empty or error result
- Invalid username format — API may reject the request
- Rate limiting or payment failure — 402 payment required if USDC not available
- Network timeout on Vercel serverless deployment
- Schema mismatch if input object is malformed

## How this service works

All-in-one API hub: Social Media, Jobs, Finance, Crypto, and Tools. Pay-per-call with x402 protocol on Base chain.
