# 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 2026-09-14).

Fetches real-time reserve, price, and token metadata for a given DEX liquidity pool on Base or Ethereum

## Facts

- Endpoint: GET https://entropy.rip/api/financial/pool/%7Bvar1%7D
- Price: $0.03/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-14
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/entropy-rip-liquidity-pool-data-f1f29ede
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_u50DiaA_IbrC8sqgZlAPn

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-f1f29ede
```

Example prompt: Can you pull the current reserve and price data for the Uniswap pool at 0x4752ba5DBc23f443c98305F8b4C71B78B4C02F23 on Base?

## When to prefer this

Use this endpoint when you need lightweight, pay-per-call access to DEX pool reserve and price data on Base or Ethereum without maintaining your own blockchain node or indexer. Prefer it for Uniswap or Aerodrome pools when you need formatted token amounts, decimal-adjusted prices, and pool metadata in a single call. It is well-suited for autonomous agents that need occasional on-chain lookups without a persistent data subscription.

## Known failure modes

- Invalid or non-existent pool address returns an error or empty response
- Unsupported DEX or chain combination may return a 400 or 404
- Pool address on wrong chain returns no data or mismatched results
- Rate limiting or payment failure returns 402 if x402 payment is not completed
- Stale data if on-chain state changes between crawl and response

## 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 pool address, chain, DEX version, token0 and token1 contract addresses, raw and formatted reserve amounts, decimal precision for each token, current price of each token relative to the other, and a timestamp of when the data was fetched.
