It is part of a broader platform offering dozens of pay-per-call API endpoints spanning data analytics, AI/ML inference, finance, crypto, infrastructure utilities, and more — all settled on the Base network using USDC.\n\nThe x402 challenge confirms the endpoint is live and accepts POST requests. The price is 20,000 base units of USDC (6 decimals), which equals $0.02 per request. Payment is made via the x402 \"exact\" scheme to a specified wallet address on Base. No API keys or rate limits are advertised; access is granted instantly upon payment.\n\nHowever, the specific endpoint `/api/v1/insurance/claims/51` is not listed among the provider's publicly advertised API categories (Data & Analytics, AI & ML, Finance & Web3, Infrastructure). There is no documentation, schema, or example response available for this particular insurance claims resource. The provider's landing page describes a uniform $0.02/request pricing model across all endpoints, which is consistent with the x402 challenge. Without further documentation, the exact shape of the response and the nature of the insurance claims data remain unknown.","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","insurance-claims-data","per-request-pricing","no-api-key-required"],"categories":["finance","data"],"synonyms":["insurance claim lookup","claims API","x402 insurance endpoint","pay-per-call insurance data","USDC API payment","lowpaymentfee insurance"],"warnings":["This specific endpoint (/api/v1/insurance/claims/51) is not listed among the provider's publicly advertised APIs — its purpose and data content are unverified.","No response schema or example response is available; the shape and content of the returned data are unknown.","No OpenAPI spec, README, or detailed documentation was found on the provider's site.","The insurance claims category may be subject to regulatory requirements depending on jurisdiction and data sensitivity."],"endpointUrl":"https://lowpaymentfee.com/api/v1/insurance/claims/51","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/51","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 ($0.02 USDC on Base).
