## 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 percall-uniswap-v4-token-price-pools-on-robinhood-chain-9486069c -d '<json body>'

Example prompt: What's the live USD price and all Uniswap v4 pools for the token at contract address 0xd95b44124e475743a7589e68f3d74008a5536d44 on Robinhood Chain — pulled straight from on-chain RPC?

## When to prefer this

Choose this endpoint when you need live, on-chain USD pricing and Uniswap v4 pool data for a specific ERC-20 token on Robinhood Chain (eip155:4663) without relying on any third-party price oracle or CEX API. It is ideal when you have the token contract address and want authoritative chain-native data including pool fee tiers, pool IDs, and USDG or ETH-anchored pricing. Prefer it over CEX spot price endpoints when the token is DEX-native or when chain-level pool topology matters.

## Known failure modes

- Invalid or non-existent contract address returns an error or empty pool list
- Contract address on wrong chain (not eip155:4663) returns no data
- Token not listed in any Uniswap v4 pool returns empty pools array
- RPC node unavailability causes timeout or 503 error
- Malformed address string returns validation error
- Payment failure (x402) blocks the request entirely
