## How to call it through Zero

```sh
zero fetch --capability speraxos-exchange-data-api-60267e49
```

Example prompt: Pull the latest exchange data for USDC/ETH trading pair from SperaxOS — I want liquidity, volume, and any AI insights on that pair right now.

## When to prefer this

Choose this endpoint when you need AI-analyzed DeFi exchange data without a traditional API key subscription, especially when operating on the Base network and comfortable with micropayments. Ideal for agents that need on-demand, pay-per-use DeFi intelligence without committing to a monthly API plan. Prefer over centralized exchange APIs when the focus is decentralized protocol data.

## Known failure modes

- Payment failure: insufficient USDC balance or failed x402 payment returns 402 Payment Required
- Invalid query parameters: malformed or missing required fields returns 400 Bad Request
- Exchange not found: querying an unsupported or unrecognized exchange returns 404 or empty result
- Rate limiting: too many rapid requests may result in throttling
- Network issues: Base network congestion may delay payment settlement and response

## 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 exchange intelligence data including trading metrics, liquidity information, volume statistics, and market analysis for the queried exchange or trading pair, delivered as structured JSON.
