Payment is settled on the Base network using USDC (USD Coin) at a cost of $0.02 per request. The provider advertises no API keys, no rate limits, and instant access — callers simply attach an X-PAYMENT header with a valid x402 payment proof.\n\nThe broader lowpaymentfee.com platform hosts a variety of pay-per-call API categories including data analytics, AI/ML inference (sentiment analysis, summarization, classification, embeddings), finance/Web3 data (price feeds, exchange rates, gas estimates), and infrastructure utilities (geocoding, validation, conversion). All endpoints share the same $0.02/request pricing model and x402 payment flow on Base.\n\nDocumentation is minimal: there is no OpenAPI spec, no detailed request/response schema, and the crawled /api, /pricing, and /README pages all resolve to a bare \"Connect wallet\" prompt with no additional content. The endpoint's actual input parameters and response structure for insurance claims data are unknown — the only confirmed detail is that it accepts POST requests and returns application/json. Callers should expect to experiment or contact the provider for schema details.","tags":[],"capabilities":["x402-payment","usdc-base","insurance-claims","pay-per-request","no-api-key","json-response"],"categories":["finance","data"],"synonyms":["insurance claims API","x402 insurance","pay-per-call claims data","USDC API","Base network API","lowpaymentfee","micro-payment API"],"warnings":["No OpenAPI or schema documentation available — request and response formats are unknown","The /api, /pricing, and /README pages all return only a 'Connect wallet' prompt with no useful content","The specific endpoint path (/insurance/claims/2) suggests a single hardcoded resource; unclear if other claim IDs are available","Insurance data may be subject to regulatory requirements (HIPAA, state insurance regulations) depending on jurisdiction and data content"],"endpointUrl":"https://lowpaymentfee.com/api/v1/insurance/claims/2","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/2","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.300","qualityRationale":"The endpoint is live (returns 402 with a valid x402 challenge), but there is no OpenAPI spec, no request/response schema, and no documentation beyond a landing page listing.
