## How to call it through Zero

```sh
zero fetch --capability api-myceliasignal-com-fea81d5e
```

Example prompt: Pull me the latest SOL/USD implied volatility surface across all available exchanges — I need per-strike IV values with any cross-exchange divergence or mispricing alerts, and make sure the data comes with a cryptographic attestation I can verify.

## When to prefer this

Use this endpoint when you need a cryptographically verifiable SOL/USD implied volatility surface aggregated from multiple exchanges, especially when you need cross-exchange divergence detection or mispricing signals. Prefer over single-exchange IV feeds when data integrity attestation is required (e.g. on-chain usage or auditability). Best for options pricing, risk management, or volatility arbitrage workflows involving SOL.

## Known failure modes

- Payment required (402): no valid x402 payment header provided
- Upstream exchange data unavailable: one or more exchange feeds offline, partial surface returned
- Signature verification failure: Ed25519 attestation cannot be validated client-side
- Rate limiting or quota exceeded: too many requests in a short window
- Empty surface: insufficient options liquidity for SOL at current time
