## How to call it through Zero

```sh
zero fetch --capability api-myceliasignal-com-b9909833
```

Example prompt: Can you get me the current sea state summary for my marine route — I need the signed oracle attestation so I can verify the data hasn't been tampered with?

## When to prefer this

Use this endpoint when you need cryptographically verifiable (Ed25519 attested) sea state summaries for a marine route, particularly in contexts where data integrity and tamper-evidence are required — such as smart contract inputs, automated maritime decisions, or trustless agent workflows. Prefer over unauthenticated weather APIs when auditability or on-chain use is needed.

## Known failure modes

- Payment not provided — returns 402 Payment Required if 0.2 USDC x402 payment is missing
- Invalid or malformed request — returns 400 if query parameters are incorrect
- Service unavailable — upstream marine data source may be temporarily unreachable
- Signature verification failure — consumer-side Ed25519 key mismatch during verification

## How this service works

Voyage route sea state summary — wave conditions along shipping route for freight and logistics planning — Ed25519 signed attestation

## Output

A cryptographically signed Ed25519 attestation containing a summary of current sea state conditions along a marine route, including wave and ocean condition data that can be independently verified for authenticity.
