It accepts POST requests and returns JSON. 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 rate limits are required — callers simply attach an X-PAYMENT header with a valid x402 payment proof.\n\nThe endpoint is part of a broader platform (lowpaymentfee.com) that offers dozens of pay-per-call APIs spanning data analytics, AI/ML inference, finance/Web3 data, and infrastructure utilities, all priced at $0.02 per request. The specific content and schema of the insurance claims response is not documented in the available crawl material, so the exact fields returned are unknown. The x402 challenge confirms the endpoint is live and accepting payment challenges with a 300-second timeout.\n\nBecause there is no OpenAPI spec, no response schema documentation, and no example responses available, integrators will need to make a paid call to discover the response format. The platform advertises no minimums, no commitments, and instant access, settling all payments on the Base L2 network.","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","insurance-claims-data","pay-per-request","no-api-key","json-response"],"categories":["finance","data"],"synonyms":["insurance claims API","claims data endpoint","x402 insurance","pay-per-call claims","USDC API payment","lowpaymentfee insurance","Base network API"],"warnings":["No OpenAPI or response schema available — response format is unknown until a paid call is made","The specific insurance claims endpoint (/api/v1/insurance/claims/29) is not listed on the provider's homepage among advertised APIs, raising questions about its provenance","No documentation exists for request body parameters or response fields","Platform pages (/api, /pricing, /README) returned only 'Connect wallet' with no useful content"],"endpointUrl":"https://lowpaymentfee.com/api/v1/insurance/claims/29","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/insurance/claims/29","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.350","qualityRationale":"The x402 challenge is live and pricing is clear ($0.02/request in USDC on Base), but there is no OpenAPI spec, no response schema, no example responses, and no documentation for this specific insurance claims endpoint.
