## 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 textokit-crypto-prices-b048456a -d '<json body>'
```

Example prompt: Can you check the current USD price, market cap, and 24-hour change for bitcoin, ethereum, and solana right now?

## When to prefer this

Choose this endpoint when you need live USD price, market cap, and 24h change for up to 20 coins identified by their CoinGecko ID, without needing an API key or managing authentication. It is ideal for pre-decision price checks, report generation, or alert triggers in agent workflows. Prefer it over manual CoinGecko API calls when operating in an x402 pay-per-call context and you want a single, clean response without quota management.

## Known failure modes

- Invalid or unsupported CoinGecko ID returns an error or empty result for that coin
- Requesting more than 20 coins may be rejected or truncated
- Using ticker symbols (BTC, ETH) instead of CoinGecko IDs (bitcoin, ethereum) will fail
- CoinGecko upstream outage may cause stale or missing data
- Malformed comma-separated input string may result in parsing errors
