## 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 cambrian-x402-api-sushiswap-v3-pools-evm-885fc8b3
```

Example prompt: Can you pull the current SushiSwap V3 liquidity pools on Ethereum mainnet for me? I want to see the available pools and their fee tiers.

## When to prefer this

Choose this endpoint when you need structured SushiSwap V3 pool data on EVM chains without managing a full blockchain node or subgraph subscription. Ideal for autonomous agents needing pay-per-query DeFi data with x402 micropayment support, avoiding API key setup. Prefer over direct RPC calls when you want normalized pool metadata without raw contract decoding.

## Known failure modes

- Payment not fulfilled (402) — x402 micropayment not completed or insufficient USDC balance
- Invalid or unsupported chain parameter — no pools returned or error response
- No matching pools for given filter parameters — empty array returned
- Rate limiting or gateway timeout if too many concurrent requests
- Malformed query parameters result in 400 bad request

## How this service works

Pay-per-use blockchain and social data for autonomous agents.

## Output

Returns an array of SushiSwap V3 pool objects for the specified EVM chain, each containing pool addresses, token pair details, fee tiers, and liquidity metrics.
