## 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-markets-intelligence-api-dd8853a3 -d '<json body>'
```

Example prompt: Pull the latest CoinGecko market data for the top DeFi tokens — prices, market caps, and 24h trading volume — and charge my Base wallet the $0.005 USDC fee per call.

## When to prefer this

Choose this endpoint when you need CoinGecko market data on-demand without managing API keys or subscriptions, and you are operating in a Web3/DeFi agent context where micropayments via USDC on Base are feasible. Ideal for AI agents that make sporadic, per-request market data calls and want to avoid monthly API billing. Prefer over direct CoinGecko API when you want AI-enriched DeFi intelligence layered on top of raw market data, or when operating in a wallet-native, identity-first environment.

## Known failure modes

- Insufficient USDC balance on Base wallet — payment fails, 402 response returned
- Invalid or missing x402 payment header — request rejected before processing
- CoinGecko upstream data unavailability or rate limiting — may return stale or partial data
- Malformed properties filter in request body — returns 400 or empty result set
- Network latency or Base chain congestion delaying payment confirmation

## 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 structured market data for cryptocurrency tokens sourced from CoinGecko, including price, market capitalization, 24-hour trading volume, price change percentages, and related DeFi market intelligence fields. The response is processed through SperaxOS AI for enhanced DeFi context. Each successful call deducts $0.005 USDC from the caller's Base wallet via the x402 payment protocol.
