Payment is settled in USDC on the Base network. The x402 challenge indicates a maximum cost of $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 provider (lowpaymentfee.com) hosts a broad catalog of pay-per-call APIs spanning data analytics, AI/ML inference, finance, crypto, and utility services, all priced uniformly at $0.02 per request. This specific endpoint falls under an insurance claims category, though the provider's landing page does not list insurance endpoints among its featured categories. The endpoint accepts POST requests and returns application/json.\n\nBecause no OpenAPI schema, request body documentation, or sample responses are available for this endpoint, the exact input parameters and response structure are unknown. The endpoint is confirmed live (returns a well-formed 402 challenge), but callers will need to experiment or contact the provider to determine the expected POST body and the shape of the returned claims data.","tags":[],"capabilities":["x402-payment","usdc-base","pay-per-request","insurance-claims","json-response","no-api-key"],"categories":["finance","data"],"synonyms":["insurance claim lookup","claims data API","insurance API","x402 insurance","pay-per-call claims","USDC API","Base network API"],"warnings":["No request body schema or documentation available for this endpoint","No example response or field descriptions provided","Insurance claims endpoint not listed among the provider's advertised API categories — unclear if this is a production or test endpoint","The specific claim ID (64) is hardcoded in the URL; unclear how to query other claims"],"endpointUrl":"https://lowpaymentfee.com/api/v1/insurance/claims/64","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/64","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.350","qualityRationale":"The endpoint is live and returns a valid x402 challenge, confirming pricing and payment details.
