It accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x8335…2913) with a maximum cost of $0.02 per request (20,000 base units at 6 decimals).\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 at $0.02 per request with no API keys, no rate limits, and no commitments. The specific endpoint listed here falls under an insurance claims path, though the provider's landing page does not explicitly document this particular route or its response schema. No OpenAPI spec, detailed field documentation, or example responses were found in the crawl.\n\nBecause the endpoint returned a valid 402 challenge with a well-formed x402 payload, it is confirmed live. However, the lack of documentation about what the insurance claims response actually contains (fields, data source, freshness) means consumers should treat this as exploratory until they can inspect a real response.","tags":[],"capabilities":["x402-payment","usdc-base","insurance-claims","pay-per-request","json-response"],"categories":["finance","data"],"synonyms":["insurance claim lookup","claims API","insurance data endpoint","x402 insurance","pay-per-call claims","USDC API","Base network API"],"warnings":["No documentation found for the /api/v1/insurance/claims/ path — it is absent from the provider's listed API catalog","No response schema or example response available; actual data content is unknown","No OpenAPI or machine-readable spec discovered","The provider site's /api, /pricing, and /README pages all returned only a 'Connect wallet' prompt with no useful content"],"endpointUrl":"https://lowpaymentfee.com/api/v1/insurance/claims/77","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/77","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, but there is no OpenAPI spec, no response schema documentation, no example responses, and the specific insurance claims path is not mentioned on the provider's own landing page.
