## 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 hcrb-in-crypto-ticker-usd-price-007e60b7 -d '<json body>'

## When to prefer this

Choose this endpoint when you need a quick, low-cost USD spot price for a cryptocurrency with a verifiable signed receipt — especially useful in agentic workflows requiring price attestation, on-chain settlement checks, or invoice generation. Prefer this over raw CoinGecko API calls when you need built-in caching, a signed audit trail, and x402 micropayment compatibility.

## Known failure modes

- Unknown or unsupported ticker symbol returns an error
- CoinGecko ID not recognized results in a lookup failure
- Stale cache may return a price up to 60 seconds old
- Network or upstream feed unavailability causes a service error
- Malformed input (missing 'symbol' field) returns a validation error
