## 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 defi-pool-top-listings-x402-paid-api-1f2c4427
```

Example prompt: Show me the top 10 stablecoin liquidity pools on Base with at least $500,000 TVL, paying per call in USDC with no account needed.

## When to prefer this

Use this endpoint when you need a ranked list of top DeFi pools by TVL on Base or Ethereum without requiring an account or API key — just pay $0.02 USDC per call. Prefer this over other pool discovery tools when you want permissionless, pay-per-use access with optional stablecoin and minimum TVL filtering.

## Known failure modes

- Payment not received or insufficient USDC — 402 response requiring payment
- Invalid chain value (not 'base', 'ethereum', or 'all') — likely 400 or unfiltered result
- limit exceeds max of 25 — may be clamped or return error
- min_tvl too high returns empty pool list
- Network or RPC issues cause stale or missing on-chain data

## How this service works

On-chain token/contract risk scanner. Pay-per-call USDC on Base via x402. No account, no KYC.

## Output

A ranked list of up to 25 DeFi liquidity pools matching the filters, including pool identifiers and TVL figures for the specified chain(s), returned after a micropayment of $0.02 USDC on Base via x402.
