## 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 speraxos-coingecko-global-defi-data-796cf829 -d '<json body>'
```

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

## When to prefer this

Choose this endpoint when you need a single authoritative snapshot of the entire cryptocurrency market without needing API keys — ideal for AI agents that can pay per-request via x402 on Base. Prefer this over CoinGecko's direct API when operating in a wallet-native or DeFi-native context and avoiding key management. It is the right choice for macro market context queries rather than per-coin lookups.

## Known failure modes

- Payment failure if insufficient USDC balance on Base or x402 payment not properly formed
- CoinGecko API rate limiting or downtime resulting in a 502/503 response
- Stale or delayed data if CoinGecko upstream is lagging
- Empty or malformed body rejected if required input wrapper fields (type, method, bodyType) are missing
- Network timeout if chat.sperax.io infrastructure is under load

## How this service works

AI-powered DeFi intelligence APIs payable via the x402 HTTP payment protocol. No API key required — pay per request with USDC on Base. Identity-only (SIWX) endpoints are free for wallets with an agentcash identity.

## Output

Returns a global market data object from CoinGecko including: total number of active cryptocurrencies and markets, total market capitalization in USD and other currencies, 24-hour trading volume, Bitcoin and Ethereum market dominance percentages, DeFi total market cap, total market cap change over 24 hours, and related statistics covering the entire cryptocurrency ecosystem.
