It is hosted at lowpaymentfee.com, a platform offering a variety of pay-per-call APIs spanning DeFi, analytics, AI, and utility categories. The specific endpoint `/api/v1/defi/makerdao/pools` returns JSON data about MakerDAO liquidity pools. Payment is settled in USDC on the Base network at $0.02 per request (20,000 base units of USDC with 6 decimals). No API keys or accounts are required; callers simply attach an x402 payment header.\n\nThe platform advertises uniform $0.02 pricing across all endpoints, no rate limits, and no minimum commitments. The x402 challenge was successfully captured with version 1 of the protocol, confirming the endpoint is live. The payment is routed to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 using the USDC contract on Base (0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913). The endpoint accepts POST requests.\n\nDocumentation is extremely sparse — the docs, pricing, and API pages all render only a \"Connect wallet\" prompt with no further technical detail. There is no OpenAPI schema, no request/response examples, and no description of what fields the MakerDAO pools response contains. The exact data returned (pool addresses, TVL, APY, collateral types, etc.) must be inferred from the endpoint name alone.","tags":[],"capabilities":["defi-data","makerdao-pools","x402-payment","usdc-base","pay-per-request","no-api-key"],"categories":["defi","finance"],"synonyms":["MakerDAO pools API","DeFi pool data","MakerDAO liquidity","Maker protocol pools","DAI pools","DeFi analytics","MakerDAO vaults"],"warnings":["No API documentation available — docs, pricing, and API pages all show only 'Connect wallet'","No OpenAPI or JSON schema describing request parameters or response format","No example responses available; actual data fields for MakerDAO pools are unknown","This specific endpoint (/api/v1/defi/makerdao/pools) is not listed on the homepage catalog, raising questions about whether it is a fully supported route"],"endpointUrl":"https://lowpaymentfee.com/api/v1/defi/makerdao/pools","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","extra":{"name":"USD Coin","version":"2"},"payTo":"0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3","scheme":"exact","network":"base","mimeType":"application/json","resource":"https://lowpaymentfee.com/api/v1/defi/makerdao/pools","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.350","qualityRationale":"The endpoint is live and returns a valid x402 challenge with clear pricing, but there is no documentation, no OpenAPI schema, no request/response examples, and no description of the data returned.
