The endpoint accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (USD Coin) at a cost of $0.02 per request (20,000 base units with 6 decimals). No API keys, rate limits, or upfront commitments are required — callers simply attach an X-PAYMENT header with a valid x402 payment proof.\n\nThe provider, lowpaymentfee.com, hosts a broad catalog of pay-per-call APIs spanning data analytics, AI/ML inference, finance, crypto, and utility services, all priced uniformly at $0.02 per request on Base. This specific endpoint falls under what appears to be an insurance domain, though the exact schema of the claims response is not documented. The x402 challenge was successfully captured (HTTP 402), confirming the endpoint is live and accepting payment challenges.\n\nNote that no OpenAPI spec, request/response schema, or detailed documentation was found for this endpoint. The input and output formats must be inferred or discovered by making an authenticated request. The provider's landing page confirms the general pricing and payment model but offers no endpoint-specific documentation for the insurance claims resource.","tags":[],"capabilities":["x402-payment","per-request-billing","usdc-settlement","base-network","insurance-claims-data","json-response","no-api-key","post-method"],"categories":["finance","data"],"synonyms":["insurance claims API","claims data endpoint","x402 insurance","pay-per-request claims","USDC API","Base network API","lowpaymentfee insurance","claims lookup"],"warnings":["No OpenAPI or schema documentation available for this endpoint","No example request or response bodies documented — input/output formats are unknown","The insurance claims resource is not described on the provider's landing page, which lists other API categories but not insurance","Endpoint appears to serve a single hardcoded claim ID (92); unclear if other IDs are supported or what the resource represents"],"endpointUrl":"https://lowpaymentfee.com/api/v1/insurance/claims/92","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/92","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).
