# Base Fresh Pools Feed

> Base Fresh Pools Feed is a paid API for AI agents from agenttoll-pi.vercel.app, paid per call via x402, $0.004/call, status unknown (last checked 2026-09-15).

Returns the most recently created Uniswap v4 pools on Base, including launched token address, funding status, and hook type classification, read directly from chain before any indexer has them

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## 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 base-fresh-pools-feed-fd98ee6d
```

Example prompt: Show me the 20 newest pools that just launched on Base in the last 15 minutes, only ones that have been funded, and tell me whether each one is using a launchpad hook or custom code.

## When to prefer this

Choose this endpoint when you need the absolute freshest pool data on Base — within seconds of creation — before any third-party indexer (DexScreener, GeckoTerminal, etc.) has picked it up. Ideal for token sniping workflows, launchpad monitoring, or any agent that needs to act on new liquidity events in near-real-time. Prefer over indexer-based endpoints when sub-minute freshness matters.

## Known failure modes

- No pools found if lookback window is too narrow or Base has low activity in that period
- Invalid parameter types (e.g. non-integer limit) return a 400 error
- limit out of range (must be 1-50) or minutes out of range (1-60) returns a validation error
- RPC latency or chain reorganizations may cause momentary gaps in coverage
- Payment failure or missing x402 payment header returns 402 Payment Required

## How this service works

Pools read straight off Base seconds after they exist, before any indexer has them: the launched token address, whether anyone has funded it yet, and whether its hook is a launchpad's or bespoke code shipped with this token

## Output

A list of recently created Base pools, each containing the launched token contract address, a boolean indicating whether liquidity has been added, and a classification of the pool's hook as either a known launchpad hook or bespoke contract code. Results are ordered by creation time and capped by the requested limit.
