How this service works
Public data and utility APIs paid per call in USDC on Base (x402). No accounts, no API keys. 174 routes: crypto/equity data, onchain reads, DNS/email/security intel, geo/weather, x402 payment diagnostics, dev utilities and more.
Output
Returns a JSON object with a list of liquidity pools for the queried token, each containing: pool contract address, fee tier (e.g. 3000 = 0.3%), total liquidity in USD, and the price of token0 per token1. Also echoes back the queried token address.
Example use cases
Assess token liquidity before swap
“Before I swap into this token at 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913, can you check how much DEX liquidity it has and which pools are available?”
Monitor pool fee tiers for arbitrage
“Show me all the DEX pools for token 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 and their fee tiers — I want to know where the most liquidity is concentrated for arbitrage.”
Get on-chain price from DEX pool
“What's the current on-chain price of token 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 based on its DEX liquidity pools?”
Technical details
Endpoint
GEThttps://anibalb.duckdns.org/x402/dex-liquidity?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need real-time on-chain DEX liquidity data for a specific token without requiring an API key or account. Ideal for DeFi agents needing to assess swap feasibility, price impact, or pool availability. Prefer over centralized exchange APIs when you need decentralized/onchain pool data specifically. Pay-per-call at $0.002 USDC makes it cost-effective for spot queries.
Side effects
- Token address not found or not indexed — empty pools array returned
- Invalid token address format — likely a 400 or malformed response
- No liquidity exists for the token — pools array returns empty
- Payment not processed correctly via x402 — 402 response requiring USDC payment on Base
- Service downtime on duckdns.org host — connection timeout or 503
