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. However, the specific endpoint listed here (/api/v1/insurance/claims/61) is not explicitly documented on the provider's landing page among the advertised API categories. The insurance claims path suggests a domain-specific data retrieval service, but no schema documentation, example payloads, or response formats are available beyond what the x402 challenge reveals.\n\nThe endpoint is confirmed live — it returns a well-formed 402 challenge with x402 version 1, specifying the USDC asset contract (0x8335…2913) on Base and a 300-second payment timeout. Without OpenAPI specs or usage documentation, the exact request body format and response structure remain unknown.","tags":[],"capabilities":["x402-payment","usdc-base","insurance-claims-data","per-request-billing","no-api-key","json-response"],"categories":["finance","data"],"synonyms":["insurance claim lookup","claims data API","x402 insurance endpoint","pay-per-call insurance","USDC micropayment API","Base network API","insurance records"],"warnings":["The /api/v1/insurance/claims/61 path is not listed among the provider's documented APIs on the landing page — it may be a test or unlisted endpoint.","No request body schema or response schema is available; callers must discover the format experimentally.","No documentation pages rendered meaningful content (pricing, README, and /api pages only show 'Connect wallet')."],"endpointUrl":"https://lowpaymentfee.com/api/v1/insurance/claims/61","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/61","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.300","qualityRationale":"The endpoint is live and returns a valid x402 challenge, but there is no OpenAPI schema, no documented request/response format, and the specific insurance claims path is not listed among the provider's advertised APIs.
