## 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-btc-usd-ohlcv-spot-price-history-360db9ef
```

Example prompt: Pull me the signed OHLCV history for BTC/USD at the 1-hour interval for the last 30 days — I need the Ed25519 batch attestation so I can verify the data on-chain.

## When to prefer this

Choose this endpoint when you need historically verifiable, cryptographically attested BTC/USD price data — especially for oracle-driven smart contracts, DeFi protocols, or any use case requiring tamper-proof OHLCV data. Prefer this over unsigned APIs when on-chain verification or trustless data pipelines are required. Best suited for intervals from 1-minute to daily, up to 60 days of history.

## Known failure modes

- Invalid or unsupported interval parameter returns an error
- Date range exceeding 60 days limit returns a rejection
- Missing required query parameters returns 400 Bad Request
- Payment not completed or x402 flow not fulfilled returns 402 Payment Required
- Signature verification failure on client side if public key mismatch
