## 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 mycealiasignal-eth-market-state-synopsis-0f25b1a7
```

Example prompt: Give me the full ETH market synopsis right now — funding rate z-score, OI change, liquidation flow, basis carry, perp regime, futures curve, and IV vs RV — with the Ed25519-signed attestation so I can verify the data freshness.

## When to prefer this

Choose this endpoint when you need a comprehensive, cryptographically attested snapshot of ETH derivatives market structure — especially when you require multiple signals (funding, OI, liquidations, basis, IV/RV) in a single atomic call with verifiable timestamps. Prefer this over assembling individual data sources when you need auditability (Ed25519 signature), regime context, and contagion framing together. Not suitable if you need a macro risk score or BTC/altcoin coverage.

## Known failure modes

- Payment not received or invalid x402 payment header — returns 402 Payment Required
- Upstream data source unavailable causing partial or failed response
- Stale cache (up to 60s old) may not reflect very recent market moves
- Ed25519 signature verification failure if response is tampered in transit
- Rate limiting or overload on the provider side returning 503

ETH market state synopsis — market stress and contagion context, plus ETH funding with z-score, OI change, liquidation flow, basis carry, perp regime and the run it sits in, order book, futures curve, IV/RV. Every input's as-of is signed. No macro risk score. 60s cache. Ed25519 signed. — Ed25519 signed attestation

## Output

A signed JSON payload containing: ETH funding rate with z-score, open interest change, liquidation flow metrics, basis carry, perp regime classification and current run context, order book snapshot, futures curve data, implied volatility, realized volatility, market stress index, contagion context, per-input as-of timestamps, and an Ed25519 cryptographic signature attesting to data authenticity. Response is cached for up to 60 seconds.
