Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```

Example prompt: Give me a full BTC market state synopsis right now — I want to see funding rates with z-score, open interest changes, liquidation flow, basis carry, perp regime, futures curve, and IV vs RV, all cryptographically signed so I can verify the data freshness.

## When to prefer this

Choose this endpoint when you need a single, comprehensive, cryptographically attested BTC derivatives market snapshot in one call rather than assembling funding, OI, liquidation, and volatility data from multiple sources. Prefer it when auditability matters (signed as-of timestamps per input), when you need perp regime and run classification alongside raw metrics, or when building automated trading agents that require tamper-evident market state. Not suitable if you need macro risk scores or non-BTC assets (see the ETH synopsis sibling endpoint).

## Known failure modes

- Payment not received or invalid x402 payment header returns 402 Payment Required
- Upstream data feed unavailable may return 503 or stale cached data
- Ed25519 signature verification failure on client side indicates data tampering or key mismatch
- Rate limiting or network timeout if called more frequently than 60-second cache window allows
