## 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-pools-data-api-7b273e88
```

Example prompt: Show me the top DeFi liquidity pools right now — I want to see which ones have the best yields and TVL so I can decide where to provide liquidity.

## When to prefer this

Choose this endpoint when you need AI-enriched DeFi pool intelligence without setting up an API key — ideal for autonomous agents that can pay per-request in USDC on Base. Prefer this over raw on-chain queries when you want pre-processed, ranked, or AI-scored pool data rather than raw blockchain state.

## Known failure modes

- 402 Payment Required if x402 USDC payment on Base is not included or is insufficient
- Invalid or malformed properties filter returns an error or empty result set
- Network/chain unavailability may cause stale or missing pool data
- Rate limiting if payment is not properly processed by the x402 facilitator
- Pools with very low liquidity may not appear in results

## 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 data about DeFi liquidity pools, likely including pool identifiers, protocols, token pairs, APY/APR rates, total value locked (TVL), and AI-derived intelligence or ranking signals to help evaluate pool attractiveness.
