Payment is settled on the Base network using USDC (USD Coin) at a cost of $0.02 per request. The endpoint requires no API keys, no rate limits, and offers instant access — you 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 & Web3, infrastructure utilities, and more — all priced at $0.02 per request. This particular endpoint falls under an insurance claims category, though the provider's landing page does not list it among its featured API groups. No OpenAPI schema, request/response examples, or detailed documentation were found for this specific endpoint, so the exact input fields and response structure are unknown.\n\nThe endpoint is confirmed live: it returns a proper HTTP 402 x402 challenge when called without payment. The x402 challenge specifies scheme \"exact\", network \"base\", asset contract 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 (USDC on Base), and a max amount of 20000 base units (i.e., $0.02 given USDC's 6 decimals). The payment recipient address is 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 with a timeout of 300 seconds.","tags":[],"capabilities":["x402-payment","usdc-base","insurance-claims","pay-per-request","no-api-key","post-endpoint"],"categories":["finance","data"],"synonyms":["insurance claim API","claims data endpoint","x402 insurance","pay-per-call insurance","USDC API","Base network API","lowpaymentfee"],"warnings":["No OpenAPI or schema documentation available for this endpoint","The insurance claims endpoint is not listed on the provider's landing page among featured APIs","Request body format and response structure are completely unknown — integration requires trial and error","No information on what data claim ID 97 actually returns"],"endpointUrl":"https://lowpaymentfee.com/api/v1/insurance/claims/97","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/97","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 402 x402 challenge, but there is no OpenAPI schema, no request/response examples, and no documentation for this specific insurance claims endpoint.
