## 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 stratalize-crypto-oracle-consensus-price-verifier-63d0402a
```

Example prompt: Can you get me a verified consensus price for BTC in USD, with a tolerance of 1%, and confirm that CoinGecko, Coinbase, and Kraken all agree before we settle this trade?

## When to prefer this

Choose this endpoint when you need a cryptographically attested, multi-source consensus price for crypto settlement, payout processing, or risk checks — especially when auditability, tamper-proof receipts, and feed-agreement scoring matter. Prefer this over a single-exchange price feed when regulatory or compliance requirements demand provable multi-source agreement and a verifiable cryptographic signature.

## Known failure modes

- Sources diverge beyond tolerance_pct — returns dispute metadata with individual feed prices and agreement score below threshold
- Invalid symbol — returns error for unrecognized or unsupported crypto ticker
- Unsupported fiat currency — returns error if the requested fiat pair is unavailable
- One or more upstream feeds (CoinGecko, Coinbase, Kraken) temporarily unavailable — may return partial agreement with reduced source count
- Payment failure — x402 payment of 0.5 USDC not processed, request rejected

## How this service works

Stratalize — attested finance, legal, healthcare, and compliance intelligence. Signed, independently verifiable receipt on every call (trust.stratalize.com/verify). Live crypto spot price verification with auditable multi-source agreement. Required param: symbol (e.g. BTC). Returns attested consensus price across CoinGecko, Coinbase, and Kraken, agreement score, sources queried, and dispute metadata when feeds diverge. Source: Stratalize Oracle consensus

## Output

Returns a cryptographically signed (ML-DSA-65) consensus spot price, an agreement score indicating how closely the sources align, the number of sources queried and agreed, fiat denomination, and dispute metadata if feeds diverge beyond the requested tolerance. A verification receipt URL at trust.stratalize.com/verify is included for independent audit.
