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, and infrastructure utilities, all priced at $0.02 per request and all using the x402 protocol on Base. This specific 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 body documentation, or response examples are available, so the exact input parameters and response structure for this insurance claims endpoint are unknown.\n\nThe endpoint is confirmed live: it returns a proper HTTP 402 challenge with x402 version 1, advertising an exact-scheme payment of 20,000 base units of USDC (6 decimals → $0.02) to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 on Base. The maximum timeout is 300 seconds.","tags":[],"capabilities":["x402-payment","usdc-base","insurance-claims","pay-per-request","no-api-key","post-endpoint"],"categories":["finance","data"],"synonyms":["insurance claim lookup","claims API","insurance data endpoint","x402 insurance","pay-per-call insurance","lowpaymentfee insurance","USDC API payment","Base network API"],"warnings":["No OpenAPI or schema documentation available for this endpoint","No request body or response body examples found","This specific insurance claims endpoint is not listed among the provider's advertised APIs on the landing page","Exact input parameters and response format are unknown — integration requires trial and error"],"endpointUrl":"https://lowpaymentfee.com/api/v1/insurance/claims/40","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/40","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 with a valid x402 402 challenge, but there is no OpenAPI schema, no request/response documentation, and no examples.
