## How to call it through Zero

```sh
zero fetch --capability api-myceliasignal-com-11d345d7
```

Example prompt: What's the current gas price on the Base network? I need a cryptographically signed attestation I can verify on-chain.

## When to prefer this

Choose this endpoint when you need a cryptographically verifiable (Ed25519-signed) Base network gas price — especially for use cases requiring trustless verification, smart contract inputs, or audit trails. Prefer over unsigned REST gas APIs when attestation provenance matters.

## Known failure modes

- Payment not received or invalid x402 payment header — returns 402 Payment Required
- Network connectivity issues fetching live Base gas data — returns 503 or timeout
- Invalid or expired attestation signature
- Malformed request — returns 400 Bad Request
