## 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-defi-markets-data-api-2e3834b2
```

Example prompt: Pull the latest DeFi market data from SperaxOS right now — I want to see current prices, liquidity, and yield metrics across major protocols, and pay for it with USDC on Base.

## When to prefer this

Choose this endpoint when you need real-time DeFi market data without a traditional API key, prefer micropayment-per-call billing in USDC on Base, or are building an AI agent that requires on-demand DeFi intelligence with pay-as-you-go economics. Ideal for agents that query infrequently and don't want subscription overhead.

## Known failure modes

- Payment failure: insufficient USDC balance or x402 payment not accepted, returns 402 Payment Required
- Invalid properties filter: malformed query parameter returns 400 Bad Request
- Rate limiting or network congestion on Base causing payment delay
- Empty result set if no markets match the specified properties filter
- Service unavailable if SperaxOS backend is down, returns 503

## 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 DeFi market intelligence including token prices, protocol TVL, liquidity pool metrics, yield rates, and other on-chain market statistics for decentralized finance assets and protocols. Each call costs $0.001 USDC paid via x402 on Base.
