## 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 coingecko-exchange-rates-via-locus-x402-30a5bafb -d '<json body>'
```

Example prompt: Pull the current BTC-denominated exchange rates for all major currencies from CoinGecko right now — I need to see how USD, EUR, GBP, and JPY compare against Bitcoin.

## When to prefer this

Choose this endpoint when you need BTC-denominated exchange rates across a broad set of fiat and crypto currencies sourced from CoinGecko, and you want pay-per-call micropayment billing via x402 with no API key management. Prefer it over direct CoinGecko API calls when operating in an agent environment that supports x402 payments natively.

## Known failure modes

- Payment failure if USDC balance insufficient for the $0.06 per-call fee
- CoinGecko API rate limiting or downtime causing upstream errors
- Malformed POST body causing request rejection
- Empty or missing input object returning validation error
- Network timeout if CoinGecko upstream is slow
