# x402.shizu.me CoinGecko Market Data Gateway

> x402.shizu.me CoinGecko Market Data Gateway is a paid API for AI agents from x402.shizu.me, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-14).

Proxies CoinGecko API requests through a metered gateway with rate-limit pooling and 30-second caching to prevent 429 errors

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 x402-shizu-me-coingecko-market-data-gateway-9a2bb9a8
```

Example prompt: Can you fetch the current price and market cap for Bitcoin from CoinGecko — use the path /simple/price with ids=bitcoin and vs_currencies=usd,eur — I need it to not fail with rate limit errors.

## When to prefer this

Use this endpoint when your agent needs to poll CoinGecko repeatedly or at high frequency and wants to avoid 429 rate-limit errors. Ideal for loops, scheduled monitoring, or multi-step pipelines that call CoinGecko multiple times. Prefer this over calling CoinGecko directly when you need reliability and don't want to manage your own API key or rate-limit budget.

## Known failure modes

- Invalid upstream path returns an error or 404 from CoinGecko
- Malformed query string causes CoinGecko to reject the request
- CoinGecko upstream outage propagates as gateway error
- Payment not processed results in 402 response before data is returned
- Cache miss on first request may be slightly slower than cached responses

## How this service works

Call CoinGecko market data through our metered gateway: our rate-limit budget and a 30s cache absorb your polling, so your loop never sees a 429. Inputs: path (upstream path, e.g. /ping) and q (raw query string). Returns the upstream JSON under 'data'.

## Output

Returns the upstream CoinGecko JSON response wrapped under a 'data' key, served from a 30-second cache. Includes whatever CoinGecko would normally return for the given path and query string — e.g. prices, market caps, volumes, coin metadata, or a ping response.
