## 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 2s-global-crypto-market-overview-6ae83c7a
```

Example prompt: What does the overall crypto market look like right now — total market cap, Bitcoin dominance percentage, ETH dominance, 24-hour volume, and how many active cryptocurrencies are there?

## When to prefer this

Use this endpoint when you need a single high-level snapshot of the entire cryptocurrency market — BTC/ETH dominance, total market cap, 24h volume — rather than data on a specific coin. Prefer this over coin-specific endpoints when the user asks about the macro crypto market or overall sentiment. Backed by CoinGecko which provides attribution-required data.

## Known failure modes

- Upstream CoinGecko API unavailable — endpoint returns error or stale data
- Payment failure via x402 — 402 response if USDC payment is not attached or insufficient
- Rate limiting or network timeout from the underlying data provider
- Malformed response if CoinGecko changes its schema

## How this service works

The (most) everything API: 575+ pay-per-call endpoints for AI agents — ground-truth data, a full AI gateway, and agent infrastructure (storage, queues, watchers). USDC via x402, no signup, no API keys, and upto billing: pay actual usage, not the quote.

## Output

Returns a JSON object with global crypto market metrics: number of active markets, BTC dominance %, ETH dominance %, total market cap in USD, total 24h volume in USD, 24h market cap change %, and count of active cryptocurrencies. Also includes data source attribution (CoinGecko).
