## 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-pool-search-on-robinhood-chain-d7129b01
```

Example prompt: Can you search Robinhood Chain's Uniswap v4 pools for the CASHCAT token and tell me the current USD price and which pools it trades in?

## When to prefer this

Use this endpoint when you need to discover Uniswap v4 liquidity pools and on-chain prices specifically on Robinhood Chain (eip155:4663). It is ideal for token discovery by symbol or name when you don't have the contract address, and for full chain scans when you do have an address. Prefer this over generic crypto price APIs when you need DEX pool-level detail (pool IDs, fee tiers, paired currencies) rather than just a spot price.

## Known failure modes

- Token symbol not found in recently indexed pools — returns empty results array
- Contract address not recognized or no pools exist for that token — count 0
- Invalid query format (malformed address) — may return error or empty results
- RPC connectivity issues causing delayed or failed chain-native price computation
- Symbol queries only cover recently indexed pools, so older or low-volume tokens may be missing

## How this service works

PerCall is an x402 payment gateway selling live crypto market data to AI agents and developers. No accounts, no API keys: request, receive HTTP 402, pay in USDC on Base, get data.

## Output

A JSON object containing the query string, source ('chain-rpc'), chain identifier ('Robinhood Chain eip155:4663'), a count of matching pools, a timestamp, and an array of pool results — each with pool ID, fee tier, USD price, and details (name, symbol, address) for both currency0 and currency1.
