## 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 beggar-bot-yield-pools-explorer-ab1786a9
```

Example prompt: Find me the top 10 USDC yield pools on Base sorted by APY, stablecoins only, with at least $1M TVL and no impermanent loss risk.

## When to prefer this

Use this endpoint when you need live DeFi yield pool data with flexible filtering by chain, token, protocol, TVL, stablecoin status, and impermanent loss risk. It is purpose-built for AI agents discovering yield opportunities on Base and other EVM chains and pays via x402 micropayments, making it suitable for autonomous agent workflows without manual API key management.

## Known failure modes

- Payment not received — returns HTTP 402 requiring $0.02 USDC via x402 on Base mainnet before data is returned
- Invalid sort parameter — unrecognized sort values may return an error or default behavior
- Limit out of range — values outside 1-50 may be rejected or clamped
- No pools match filters — valid request but empty result set if filters are too restrictive
- Chain name typo — misspelled chain names may return no results or an error

## How this service works

Paid: /v1/verify, /v1/risk, /v1/receipt cost $0.01 USDC per call on Base mainnet via x402 (payTo 0x719227f384b66BFEF00093D6d8d32fA9dC2B40e7); utilities analyze Base mainnet (USDC 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913) by default, network=base-sepolia optional; /v1/receipt/verify and discovery files are free. Operator: Beggar Bot.

## Output

A JSON list of yield pool objects, each containing pool identifier, protocol/project name, chain, token symbol, APY, base APY, TVL in USD, and stablecoin/IL metadata, filtered and sorted according to the query parameters provided.
