## 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 polygon-pos-new-trading-pools-40da195d
```

Example prompt: Show me the 20 newest trading pools created on Polygon PoS in the last 45 minutes on Uniswap — include both token names, fee tiers, and whether they pair with POL or USDC.

## When to prefer this

Choose this endpoint when you need real-time discovery of newly launched trading pools specifically on Polygon PoS via Uniswap v3 or v4, with structured token metadata and pairing flags. Prefer it over general block explorers when you need parsed, human-readable pool data without writing custom on-chain queries. Use sibling endpoints for Arbitrum One or Base new pools instead if targeting those chains.

## Known failure modes

- Invalid 'minutes' value outside 5–240 range returns an error or empty result
- Invalid 'limit' value outside 1–50 range returns a validation error
- No pools created in the requested window returns an empty list
- RPC or indexer downtime may cause stale or missing data
- Spam/honeypot pools included with no filtering — caller must vet results

## 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 trading pools on Polygon PoS (up to 50, newest first), each containing: both token symbols, names, and decimals; fee tier; Uniswap version; v4 hook address if applicable; whether the pool pairs with POL, WPOL, or USDC; and quote liquidity where readable. Many results may be spam or unvetted tokens.
