# DopamineDesk Pool Liquidity Lookup

> DopamineDesk Pool Liquidity Lookup is a paid API for AI agents from ai-data-marketplace-1042299154756.us-central1.run.app, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-15).

Returns real-time DEX liquidity pool data including token symbols, reserves, and total value locked (TVL) for a given pair contract address.

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 dopaminedesk-pool-liquidity-lookup-d7141f53
```

Example prompt: Can you look up the current liquidity and TVL for the DEX pool at address 0x88e6...abc on Base? I want to see the token reserves and how much total value is locked.

## When to prefer this

Use this endpoint when you need quick, structured liquidity data for a specific DEX pair contract — particularly reserve depths and TVL — without building your own on-chain RPC calls. It is well-suited for pre-trade slippage estimation, due diligence on new pools, or feeding liquidity metrics into a DeFi agent workflow. Prefer it over raw RPC calls when you want normalized output (USD TVL, token symbols) with minimal integration overhead and pay-per-use pricing.

## Known failure modes

- Invalid or non-existent pool_address returns an error or empty result
- Unsupported chain id causes a lookup failure
- Pool exists but has zero liquidity, returning zeroed reserve fields
- Rate limiting or payment failure (x402) blocks the request
- Stale or delayed on-chain data may cause TVL to lag actual state

## How this service works

Fetch live pair price, liquidity, volume, and price-change fields for a DEX pool address from DexScreener.

## Output

Returns a JSON object with the pool contract address, the two token symbols (token0_symbol, token1_symbol), their respective reserve amounts (reserve0, reserve1), and the total value locked in USD (tvl_usd). Example output shows a USDC/WETH pool with $300M TVL.
