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/79` — is not documented on the provider's landing page among the advertised API categories. It is live and returns a proper 402 challenge, but its exact response schema and the nature of the insurance claims data it returns are undocumented.\n\nBecause there is no OpenAPI spec, no example responses, and no documentation specific to this insurance claims endpoint, the actual data returned is unknown. Callers should be aware that this endpoint may return mock or placeholder data, as the provider's site appears to be a demonstration of low-fee x402 micropayments rather than a specialized insurance data service.","tags":[],"capabilities":["x402-payment","usdc-base-network","pay-per-request","insurance-claims-data","json-response","no-api-key"],"categories":["finance","data"],"synonyms":["insurance claims API","x402 insurance endpoint","pay-per-call insurance data","USDC micropayment API","Base network API","lowpaymentfee insurance"],"warnings":["This specific endpoint (/api/v1/insurance/claims/79) is not listed among the provider's documented APIs on the landing page.","No OpenAPI spec or response schema is available — the data returned is unknown.","The provider site appears to be a micropayment demonstration platform; insurance claims data may be mock/placeholder.","No documentation beyond the x402 challenge was found for this endpoint."],"endpointUrl":"https://lowpaymentfee.com/api/v1/insurance/claims/79","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/79","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 402 challenge, but there is no documentation, no OpenAPI spec, no example responses, and the insurance claims endpoint is not listed among the provider's advertised APIs.
