## 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 myceliasignal-eth-usd-implied-volatility-surface-oracle-a3736063
```

Example prompt: Can you pull the current ETH/USD implied volatility surface — ATM IV, skew, and term structure — with a signed attestation so I can use it in my on-chain options pricing model?

## When to prefer this

Choose this endpoint when you need a cryptographically verifiable, multi-strike and multi-expiry ETH implied volatility surface for use in on-chain protocols, DeFi derivatives pricing, risk models, or any context where trustless attestation of volatility data is required. Prefer over raw exchange APIs when you need aggregated options coverage (690+ contracts) with a signed oracle format.

## Known failure modes

- Deribit options data unavailable or stale — may return error or reduced coverage
- Insufficient options liquidity for certain expiries — incomplete term structure
- Payment not confirmed — 402 Payment Required response
- Rate limiting — too many requests in short window
- Ed25519 signing service failure — attestation cannot be generated

## How this service works

ETH implied volatility surface — ATM IV, skew, term structure from 690+ Deribit options — Ed25519 signed attestation

## Output

A cryptographically attested data payload containing the ETH/USD implied volatility surface: at-the-money implied volatility (ATM IV), volatility skew across strikes, and term structure across expiries, all computed from 690+ live Deribit options, signed with an Ed25519 key for trustless verification.
