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 same x402 payment mechanism on Base. This particular endpoint falls under what appears to be an insurance or claims domain, though no detailed documentation, request schema, or response schema is available beyond the generic \"Premium API Access\" label.\n\nBecause there is no OpenAPI spec, no example request/response payloads, and no documentation describing what fields the insurance claims endpoint accepts or returns, the actual utility and data content of this endpoint remain unclear. The endpoint is confirmed live (returns a proper 402 challenge), but consumers should be aware that the lack of documentation makes integration speculative.","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","insurance-claims-data","pay-per-request","no-api-key","post-method"],"categories":["finance","data"],"synonyms":["insurance claims API","claims data endpoint","x402 insurance","pay-per-call claims","USDC API","Base network API","lowpaymentfee"],"warnings":["No OpenAPI or schema documentation available for this endpoint","No example request or response payloads — actual data content is unknown","The endpoint description is generic ('Premium API Access') and does not describe insurance claims functionality","Provider documentation pages (/api, /pricing, /README) are gated behind wallet connection and returned no useful content"],"endpointUrl":"https://lowpaymentfee.com/api/v1/insurance/claims/91","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/91","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 402 challenge, confirming it accepts payments on Base in USDC at $0.02 per call.
