## How to call it through Zero

```sh
zero fetch --capability crypto-price-lookup-via-coingecko-cc824207
```

## When to prefer this

Use this endpoint when you need real-time USD price data for one or more cryptocurrencies identified by their CoinGecko IDs. It is ideal for portfolio tracking, DeFi decision-making, price alerting, or any workflow that needs live market prices at low cost ($0.002 per call). Prefer this over free public APIs when operating in a paid agent context that already handles x402 micropayments.

## Known failure modes

- Invalid or misspelled CoinGecko IDs return empty or partial data
- Missing 'ids' query parameter causes a 400 or empty response
- Payment not completed results in 402 Payment Required
- Rate limiting or CoinGecko API downtime may cause 503 or stale data
- Very new or obscure tokens may not be listed on CoinGecko and return no price
