## 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 rotary-agency-coingecko-proxy-api-de4d89cd
```

Example prompt: Pull the current price, market cap, and 24-hour trading volume for Bitcoin and Ethereum in USD from the CoinGecko feed — I need the latest snapshot right now.

## When to prefer this

Choose this endpoint when you need CoinGecko market data on a pay-per-call basis without managing a CoinGecko API key or subscription. It is suitable for infrequent or burst queries where a $0.002/call cost is acceptable and you want zero-setup access to crypto pricing data. Prefer direct CoinGecko API access for high-volume, latency-sensitive applications.

## Known failure modes

- CoinGecko upstream rate limit or downtime causes 5xx or timeout response
- Invalid coin ID returns empty or error JSON
- Missing required query parameters may return a 400 bad request
- Payment verification failure (x402) returns 402 Payment Required
- Network latency from proxy layer adds response delay
