Payment is settled in USDC on the Base network. The x402 challenge indicates a maximum cost of $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 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 at $0.02 per request. This specific endpoint falls under an insurance claims category, though the provider's landing page does not list it among the featured APIs. The response MIME type is application/json, and the endpoint accepts POST requests.\n\nBecause there is no OpenAPI schema, no documentation beyond the landing page, and no example request/response payloads available, the actual structure of the insurance claims data returned is unknown. Callers should expect a JSON object but will need to experiment to determine the exact fields and semantics.","tags":[],"capabilities":["x402-payment","usdc-base","pay-per-request","insurance-claims","json-response","no-api-key"],"categories":["finance","data"],"synonyms":["insurance claim lookup","claims data API","x402 insurance","pay-per-call claims","USDC API","Base network API","lowpaymentfee"],"warnings":["No OpenAPI or schema documentation available for this endpoint","The /api/v1/insurance/claims/67 path is not listed among the provider's featured APIs on the landing page","Request body format and response structure are completely unknown","Single hardcoded claim ID (67) in the URL — unclear if other IDs are supported or how to discover them"],"endpointUrl":"https://lowpaymentfee.com/api/v1/insurance/claims/67","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/67","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.350","qualityRationale":"The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base), but there is no OpenAPI schema, no request/response examples, no documentation for this specific insurance claims endpoint, and the landing page doesn't even list this endpoint among its featured APIs.
