The provider operates a broader platform offering dozens of pay-per-request APIs spanning data analytics, AI/ML inference, finance/Web3 data, and utility services—all settled on the Base network using USDC via the x402 protocol.\n\nThe specific endpoint listed here is described only as \"Premium API Access\" and returns invoice-related data in JSON format when a valid x402 payment header is supplied. The x402 challenge confirms the endpoint is live, accepts POST requests, and charges up to 20,000 base units of USDC (0.02 USD) per call. The asset address `0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913` corresponds to native USDC on Base. Payment is sent to `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` with a 300-second timeout.\n\nDocumentation is extremely sparse—the docs, API, pricing, and README pages all render only a \"Connect wallet\" prompt with no further content. There is no OpenAPI schema, no request/response examples, and no description of what the invoice endpoint actually returns or what parameters it accepts. The broader site advertises a uniform $0.02/request pricing model with no API keys, no rate limits, and instant access.","tags":[],"capabilities":["x402-payment","usdc-settlement","base-network","stripe-invoice-access","pay-per-request","no-api-key"],"categories":["finance","infrastructure"],"synonyms":["stripe invoice API","x402 paid API","USDC micropayment API","Base network API","pay-per-call endpoint","lowpaymentfee"],"warnings":["No API documentation available—docs, pricing, and README pages all show only 'Connect wallet'","No request or response schema provided; impossible to know what parameters are accepted or what data is returned","Endpoint path references a specific invoice ID (141), suggesting it may be a single static resource rather than a parameterized API","The broader site lists many API categories but none match this specific Stripe invoices path, raising questions about completeness"],"endpointUrl":"https://lowpaymentfee.com/api/v1/stripe/invoices/141","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/stripe/invoices/141","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.300","qualityRationale":"The x402 challenge is live and confirms pricing and network details, but there is zero documentation on what this endpoint accepts or returns.
