## 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-market-overview-api-86e05661 -d '<json body>'
```

Example prompt: Give me an AI-powered overview of the current DeFi market — I want to know what's trending, how liquidity looks, and the overall market sentiment right now, paid via x402.

## When to prefer this

Choose this endpoint when you need a quick, AI-synthesized overview of the entire DeFi market without managing API keys or subscriptions — pay only $0.005 USDC per call via x402. Ideal for agents, dashboards, or digest pipelines that need periodic DeFi intelligence snapshots. Prefer this over raw on-chain data queries when you want a human-readable, AI-interpreted summary rather than raw protocol-level data.

## Known failure modes

- Payment failure: x402 payment not received or USDC balance insufficient — returns 402 Payment Required
- Malformed request body: body does not conform to expected schema — returns 400 Bad Request
- Upstream data unavailability: on-chain or DeFi data sources temporarily unreachable — returns 503 or degraded response
- Rate limiting or payment processing delay causing timeout
- Empty or stale market data if underlying analytics pipeline is lagging

## 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

An AI-generated summary of current DeFi market conditions, including key metrics such as total value locked (TVL), dominant protocols, yield trends, market sentiment, liquidity conditions, and notable on-chain activity. The response is structured as an intelligence report produced by SperaxOS's AI layer, covering the broader DeFi ecosystem at the time of the request.
