It is part of a broader suite of pay-per-call APIs offered by the same provider, spanning data analytics, AI/ML inference, finance, crypto, and utility services. All endpoints use the x402 payment protocol on the Base network, settling in USDC.\n\nThe specific endpoint `/api/v1/defi/COMP/liquidity` accepts POST requests and returns JSON. The x402 challenge confirms the endpoint is live, advertising a maximum cost of 20,000 base units of USDC (0.02 USD) per call. No API keys or accounts are required — callers authenticate solely via the x402 payment header. The provider advertises no rate limits and instant access.\n\nDocumentation beyond the landing page is extremely sparse; the /docs, /pricing, /api, and /README pages all returned only a \"Connect wallet\" prompt with no substantive content. There is no OpenAPI schema, no example request/response payloads, and no detailed description of what fields the liquidity response contains. The endpoint is confirmed live (402 challenge captured), but the actual data quality and response format remain unknown.","tags":[],"capabilities":["defi-liquidity-data","comp-token","x402-micropayment","usdc-payment","base-network","pay-per-request","no-api-key","json-response"],"categories":["defi","finance","crypto"],"synonyms":["COMP liquidity","Compound token liquidity","DeFi liquidity API","COMP DeFi data","crypto liquidity endpoint","Compound protocol data"],"warnings":["No documentation available — /docs, /pricing, /api, and /README pages all return only a wallet-connect prompt with no content.","No OpenAPI or schema describing request parameters or response fields.","Response format and data fields for COMP liquidity are completely unknown — cannot verify data quality.","This specific endpoint (/api/v1/defi/COMP/liquidity) is not listed on the provider's landing page among their advertised APIs, raising questions about its status."],"endpointUrl":"https://lowpaymentfee.com/api/v1/defi/COMP/liquidity","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/COMP/liquidity","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.350","qualityRationale":"The endpoint is confirmed live via a valid x402 402 challenge, and pricing is clear ($0.02 USDC on Base).
