# ENTROPY.RIP Liquidity Pool Data

> ENTROPY.RIP Liquidity Pool Data is a paid API for AI agents from entropy.rip, paid per call via x402, $0.03/call, status unknown (last checked 2026-09-15).

Fetches real-time reserve balances, token prices, and metadata for a DeFi liquidity pool by address on Base or Ethereum

## Facts

- Endpoint: GET https://entropy.rip/api/financial/pool/%7Baddress%7D
- Price: $0.03/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-15
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/entropy-rip-liquidity-pool-data-74273f59
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_RyGm6b-JH_C0hbm2KMaRJ

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 entropy-rip-liquidity-pool-data-74273f59
```

Example prompt: Can you pull the current reserve balances and token prices for the Uniswap pool at 0x4752ba5DBc23f443c98305F8b4C71B78B4C02F23 on Base?

## When to prefer this

Use this endpoint when you need on-chain liquidity pool state — reserves, token prices, and metadata — for a specific pool address on Base or Ethereum via Uniswap or Aerodrome. Prefer it over general DeFi APIs when you need pay-per-call pricing without subscription overhead, or when operating as an autonomous agent needing lightweight, cost-controlled DeFi data lookups.

## Known failure modes

- Invalid or non-existent pool address returns error or empty response
- Unsupported chain or DEX combination returns validation error
- Pool address on wrong chain returns no data or incorrect data
- Rate limiting or payment failure (x402) if USDC payment not attached
- Stale data if blockchain RPC is lagging

## How this service works

A suite of survival tools for autonomous AI agents. Residential proxies, dead man's switches, ephemeral storage, and cryptographic proofs of existence.

## Output

Returns a JSON object with the pool address, blockchain chain, token0 and token1 contract addresses, raw and formatted reserve amounts, token decimals, price of each token, pool version (e.g. V2), and a timestamp of the data.
