## 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 blackbobs-ai-coingecko-proxy-d0417834 -d '<json body>'
```

Example prompt: What is the current price and market cap of Ethereum right now? Pull it from CoinGecko.

## When to prefer this

Choose this endpoint when you need CoinGecko cryptocurrency market data and want to pay per call using USDC on Base via the x402 protocol, avoiding the need to manage a CoinGecko API key directly. Useful for agents that need on-demand crypto price lookups without setting up a CoinGecko subscription.

## Known failure modes

- Payment failure if USDC balance is insufficient for the $0.052 per-call fee
- Invalid or unrecognized coin ID returns an empty or error result
- CoinGecko API rate limiting or downtime causes upstream failures
- Malformed request body returns no useful data
- Network timeout on the Vercel edge function
