## FAQ

### How do I pay for the data endpoints?

Payments are handled via the x402 protocol in USDC on the Base mainnet, allowing for pay-per-call usage without an account or subscription.

### Is there a way to test the tools before paying?

Yes, every data endpoint includes a free preview so agents can sample the payload before committing to a payment.
