# Crypto Global Market Overview

> Crypto Global Market Overview is a paid API for AI agents from crypto.apitoll.cloud, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-15).

## 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 crypto-global-market-overview-1b7cddfb
```

Example prompt: Give me the current global crypto market snapshot — total market cap, 24h volume, and Bitcoin and Ethereum dominance percentages right now.

## When to prefer this

Use this endpoint when you need a high-level macro view of the entire crypto market in a single call — especially BTC/ETH dominance, total market cap, or overall 24h momentum — rather than data on a specific coin or protocol. Ideal for dashboards, market summaries, or sentiment checks.

## Known failure modes

- Upstream CoinGecko data unavailable: may return stale or error response
- Payment failure (402): USDC payment not completed, endpoint inaccessible
- Rate limiting or quota exceeded: too many calls in a short period
- Network timeout: external data source slow to respond

## How this service works

A snapshot of the total crypto market: aggregate market capitalization in USD, 24-hour trading volume, Bitcoin and Ethereum dominance percentages, 24h market-cap change, and the number of active cryptocurrencies and markets. The macro view in one call. Sourced from CoinGecko.

## Output

A JSON object containing: totalMarketCapUsd (aggregate market cap in USD), totalVolume24hUsd (24h trading volume), btcDominancePct (Bitcoin's market share %), ethDominancePct (Ethereum's market share %), marketCapChange24hPct (24h change in total market cap), activeCryptocurrencies (count of active coins), markets (count of active markets), asOf (timestamp), and source attribution (CoinGecko).
