## 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 arbitrum-one-new-trading-pools-05ad70cc
```

Example prompt: Show me the 10 newest Uniswap pools created on Arbitrum One in the last 30 minutes, including both token names, fee tiers, and whether any pair with ETH or USDC.

## When to prefer this

Use this endpoint when you need real-time discovery of newly created Uniswap v3/v4 liquidity pools specifically on Arbitrum One, with enriched token metadata and pair-type flags in a single call. Prefer it over generic block explorers when you need structured, parsed pool data including fee tiers and v4 hooks without writing your own contract decoding logic.

## Known failure modes

- Invalid minutes value outside 5–240 range returns an error or default
- Invalid limit value outside 1–50 range returns an error or default
- Look-back window capped at ~12,000 blocks (~50 minutes on Arbitrum) regardless of minutes parameter
- No pools found in window returns empty list
- RPC or indexing outage may return stale or empty data
- Spam pools dominate results with unrecognized token names

## How this service works

Pay-per-call data for AI agents, paid in USDC on Base with x402: token risk checks (rug check) on Base, Ethereum, Arbitrum, Optimism, Polygon and Solana, onchain reads (balances, transactions, gas, contracts, NFTs, whale trades, new pools, ENS and Basenames), ECB exchange rates, and Canadian sales tax and business days.

## Output

A list of newly created Uniswap v3/v4 pools on Arbitrum One, each with: both token symbols, names, and decimals; the pool's fee tier; v4 hook address if applicable; a flag indicating whether the pool pairs with ETH, WETH, or USDC; and quote liquidity where readable. Results are ordered newest-first. Note: many new pools are unvetted and may be spam.
