How this service works
HALOWERK defiwerk — bezahlte Endpunkte nach x402. Preise in USDC auf Base Mainnet.
Output
Returns liquidity metrics for the specified DeFi pool, including data about the pool's liquidity depth, token composition, and relevant on-chain stats, either queried by direct pool contract address or by token pair plus DEX identifier on the requested EVM chain.
Example use cases
Arbitrage opportunity scouting
“Check the liquidity depth for the WBTC/USDC pair on Uniswap V3 on Arbitrum at the 3000 ppm fee tier — I want to know if there's enough liquidity to run an arb strategy.”
DeFi dashboard pool enrichment
“Pull liquidity data for pool address 0x88e6A0c2dDD26FEEb64F039a2c41296FcB3f5640 on Ethereum so I can display it in my DeFi dashboard.”
Fee tier comparison for LP decision
“I'm thinking about providing liquidity to the DAI/USDC pair on Uniswap V3 on Polygon — can you look up liquidity for both the 100 and 500 ppm fee tiers so I can see which is deeper?”
Technical details
Endpoint
POSThttps://defi.netzhandwerker.de/pool/liquidityWhen to prefer
Use this endpoint when you need on-chain liquidity data for a specific DEX pool on Base, Ethereum, Arbitrum, Optimism, or Polygon, and want a simple paid API call (0.005 USDC via x402) rather than running your own RPC node or indexer. Prefer this over free alternatives when reliability, structured output, and multi-chain support without infrastructure overhead matter. Particularly useful for agents that need to assess pool depth before executing swaps, providing liquidity, or building DeFi dashboards.
Side effects
- Invalid pool address format (must be 0x-prefixed 40-char hex) returns validation error
- Pool not found for given token_a/token_b/dex combination returns empty or error
- Unsupported chain value outside the allowed enum returns schema validation error
- Missing both pool address and the token_a+token_b+dex trio returns a bad request error
- Payment failure or insufficient USDC balance via x402 results in 402 response
- Unrecognized DEX id for the specified chain returns not-found error
