## 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 vibes-api-hub-coingecko-markets-9f5ddb42 -d '<json body>'
```

Example prompt: Show me the top 25 cryptocurrencies by market cap priced in USD — I want to see current prices, rankings, and volume.

## When to prefer this

Choose this endpoint when you need a broad market overview of many cryptocurrencies at once — ranked by market cap — rather than a deep dive on a single coin. It is ideal for building leaderboards, dashboards, or daily briefings. Prefer this over single-coin endpoints when the user wants a list or ranking. The x402 pay-per-call model makes it cost-effective for on-demand queries rather than continuous polling.

## Known failure modes

- Invalid vs_currency value returns an error or empty result
- per_page value out of supported range may cause a 400 or unexpected truncation
- CoinGecko rate limits or downtime may result in 502/503 responses from the proxy
- Missing required vs_currency may default or fail depending on server implementation
- Payment failure on Base chain blocks the call before it reaches CoinGecko
