## 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-coin-data-api-3ed4f9e8 -d '<json body>'
```

Example prompt: Pull up the AI-powered DeFi intelligence on Ethereum from SperaxOS — I want the latest coin data and analytics, and just pay the $0.001 USDC fee automatically.

## When to prefer this

Choose this endpoint when you need per-request, keyless DeFi coin intelligence with USDC micropayments on Base via x402 — ideal for agents that don't want to manage API subscriptions and want AI-enriched on-chain token analytics from SperaxOS rather than raw exchange data.

## Known failure modes

- Insufficient USDC balance on Base — payment fails, 402 returned with payment instructions
- Invalid or unrecognized coin identifier — 404 or empty result
- Network congestion on Base causing payment confirmation delay
- Rate limiting if payment not settled in time
- HEAD method returns no body — data must be fetched via GET after confirming payment

## 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 AI-powered DeFi intelligence data for the requested coin/token, including market metrics, on-chain analytics, and token-level insights. As a HEAD request, response metadata and headers confirm data availability and payment status; full data payload would be returned on a corresponding GET.
