It accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x8335…2913) with a maximum cost of 20,000 base units, which equals $0.02 per request (USDC uses 6 decimals).\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 with no API keys, no rate limits, and no minimum commitments. This specific endpoint falls under an insurance claims category, though the exact data returned (claim details, status, adjudication info, etc.) is not documented beyond the generic \"Premium API Access\" label.\n\nBecause there is no OpenAPI schema, no request/response examples, and no documentation beyond the landing page listing, the precise input parameters and output structure are unknown. Agents should expect a JSON response but will need to experiment or contact the provider for field-level details.","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","insurance-claims","pay-per-call","no-api-key","json-response"],"categories":["finance","insurance"],"synonyms":["insurance claim lookup","claim data API","x402 insurance","pay-per-request claims","USDC micropayment API","Base network API","lowpaymentfee"],"warnings":["No API documentation, OpenAPI spec, or response schema available for this endpoint","The exact input parameters for the POST body are undocumented","The nature of the insurance claims data (synthetic, real, demo) is unclear","Provider site pages beyond the landing page return only a 'Connect wallet' prompt with no content"],"endpointUrl":"https://lowpaymentfee.com/api/v1/insurance/claims/66","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/66","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.350","qualityRationale":"The endpoint is live (returns a valid 402 x402 challenge) and pricing is clear ($0.02 USDC on Base).
