## 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 x402-crypto-ohlcv-price-data-api-38c8f7c4
```

Example prompt: Can you fetch the current price and OHLCV data for Bitcoin (btc-bitcoin) — I need the name, price_usd, and volume fields?

## When to prefer this

Choose this endpoint when you need pay-per-call crypto price or OHLCV data without a subscription, especially when operating in an x402-compatible agent environment that can pay $0.005 USDC per query on Base or Solana mainnet. Ideal for low-frequency spot lookups where a full data subscription is overkill.

## Known failure modes

- Invalid or unknown coin identifier returns an error or empty response
- Missing required 'coin' parameter causes a 400 bad request
- Payment failure (insufficient USDC balance or x402 handshake error) results in 402 Payment Required
- Requesting non-existent fields may return null or omit those fields silently
- Rate limiting or backend data provider downtime may cause 5xx errors
