DEX liquidity pool check API for Base pairs

$0.01 per call · failed calls are never charged · no account or subscription: pay per call with a card key or USDC

Check a Base DEX pool before you trade: give a pair address and get the verified DEX, both tokens, reported liquidity, 24h volume and trades, and pair age from DexScreener, or read on Base when it is unavailable, with source and retrieval time. Missing fields are null; an unknown pair returns 404. Market data only, no risk assessment. Use to confirm a pair is real and deep enough before trading; token red flags: token_report.

Request

Over HTTP, with a card key from /credits:

curl -H "Authorization: Bearer adt_…" "https://tools.funwords.eu/liquidity-pool-audit?address=0x98c7A2338336d2d354663246F64676009c7bDa97"

Or one of your 25 free calls, no key:

curl "https://tools.funwords.eu/liquidity-pool-audit?address=0x98c7A2338336d2d354663246F64676009c7bDa97&trial=1"

Without a key, the same URL answers 402 Payment Required with x402 and MPP terms, so an agent with a wallet pays per call in USDC (Base, Polygon, Arbitrum or Solana over x402; Base or Tempo over MPP) and retries.

Details and limits

Looks up a pair address on Base through DexScreener and returns the verified DEX, pair URL, token details, liquidity, volume, 24-hour trades, and pair age when supplied by the source. source identifies DexScreener and retrievedAt is the retrieval timestamp. Missing source fields are null; this endpoint does not assess pool security or investment risk. When DexScreener is unavailable, source is Base on-chain: the tokens and DEX (by factory) are read from the pool contract, liquidityUsd is twice the balance of a USD-stablecoin side (null otherwise), and price, volume, trades and age are null. Returns 404 when no matching Base pair is found. Example market values and timestamp are illustrative snapshots, not live guarantees.

Questions

Where does the data come from?

DexScreener, with the source and retrieval time in every answer.

Does it assess pool security?

No. It reports market data only; for token red flags use /token-report.

How do I pay?

Each successful call costs $0.01; failed calls are not charged. The first 25 calls are free. Then pay with card credits (from $1; the key goes in an Authorization header or, for clients that can only fetch a URL, as api_key= in the URL) or per call in USDC over x402 or MPP. No account is needed.
