It is part of a broader API platform hosted at lowpaymentfee.com that offers data & analytics, AI/ML, finance/Web3, and infrastructure endpoints, all priced at $0.02 per request and settled in USDC on the Base network.\n\nThe specific endpoint `/api/v1/defi/PEPE/liquidity` accepts POST requests and returns JSON. Payment is handled inline via the x402 protocol: callers include an X-PAYMENT header with a signed payment of up to 20,000 base units of USDC (0.02 USD, since USDC uses 6 decimals) to the provider's address on Base. No API keys or account registration are required — access is granted per-request upon valid payment. The x402 challenge confirms the endpoint is live and accepting payments.\n\nNote that while the landing page lists many API categories (analytics, AI, finance, infrastructure), this specific listing covers only the PEPE liquidity endpoint. Documentation beyond the landing page is extremely sparse — the /docs, /api, /pricing, 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 documentation describing the response format or accepted parameters for this endpoint.","tags":[],"capabilities":["defi-liquidity-data","pepe-token","x402-payment","usdc-base-network","per-request-micropayment","no-api-key","json-response"],"categories":["defi","finance"],"synonyms":["PEPE liquidity","DeFi liquidity API","PEPE token liquidity pool","crypto liquidity data","PEPE DeFi","token liquidity endpoint","meme coin liquidity"],"warnings":["No API documentation available — /docs, /pricing, /api, and /README pages all return only 'Connect wallet' with no content","No OpenAPI or schema describing request parameters or response format for this endpoint","The specific /api/v1/defi/PEPE/liquidity path is not listed on the landing page (landing page shows finance/crypto endpoints but not defi/PEPE/liquidity specifically)","Response format and data quality are completely unverifiable from available materials"],"endpointUrl":"https://lowpaymentfee.com/api/v1/defi/PEPE/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/PEPE/liquidity","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 402 challenge with clear pricing ($0.02 USDC on Base).
