## 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 x402-hub-metat-endpoint-0a3d7bdc -d '<json body>'
```

Example prompt: Query the X402 Hub metat endpoint with the search term 'technology trends 2025' and return whatever data it finds — it costs $0.075 USDC per call paid on Base.

## When to prefer this

Choose this endpoint when you need one-off, pay-per-call access to one of the 63 APIs aggregated on X402 Hub without committing to a subscription, and you are operating in a Base-compatible wallet environment that can handle x402 micropayment flows. It is ideal for agent workflows that need flexible, cost-controlled API access billed in USDC.

## Known failure modes

- Insufficient USDC balance causes payment failure and 402 response
- Ambiguous or unsupported query string may return empty or error data object
- Upstream API unavailability causes proxy failure with no data returned
- Malformed query input returns validation error
- Rate limiting by upstream provider may cause intermittent failures
