## 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 coockies-ai-coingecko-markets-db6d62e7 -d '<json body>'
```

Example prompt: Can you pull the current market data for the top 20 cryptocurrencies by market cap, priced in USD, including their 24-hour price change percentages?

## When to prefer this

Choose this endpoint when you need structured, production-ready cryptocurrency market data from CoinGecko without managing a CoinGecko API key, paying per-call via x402 on Base chain. Ideal for agents that need occasional crypto market lookups without a monthly subscription commitment.

## Known failure modes

- Payment failure on Base chain results in 402 error and no data returned
- Invalid or unsupported coin IDs return empty or error results
- CoinGecko rate limiting or downtime causes upstream failures
- Malformed request parameters result in API errors
- Unsupported vs_currency value causes request failure
