It is part of a broader platform that offers dozens of pay-per-request API endpoints spanning data analytics, AI/ML inference, finance/Web3 data, and infrastructure utilities — all gated via the x402 protocol on the Base network, settled in USDC.\n\nThe specific endpoint listed here costs $0.02 per request (20,000 base units of USDC with 6 decimals). Payment is made via the x402 `exact` scheme: callers include an `X-PAYMENT` header with a signed payment authorization, and the server fulfills the request once payment is verified. The payment is directed to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` on Base mainnet, using the USDC contract at `0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913`. The endpoint accepts POST requests and returns `application/json`.\n\nDocumentation is extremely sparse — the docs, pricing, API, 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 Stripe invoice endpoint actually returns or what parameters it accepts. The platform advertises no API keys, no rate limits, and instant access, but the actual behavior of this specific invoice endpoint is undocumented beyond its title \"Premium API Access.\"","tags":[],"capabilities":["x402-payment-gating","usdc-settlement","base-network","stripe-invoice-access","pay-per-request","no-api-key-required"],"categories":["finance","infrastructure"],"synonyms":["x402 API","pay-per-call API","USDC micropayment API","Stripe invoice API","Base network API","lowpaymentfee","crypto-gated endpoint"],"warnings":["No documentation available — docs, pricing, API, and README pages all show only 'Connect wallet' with no content","No request or response schema provided; callers cannot know what parameters to send or what data to expect","The endpoint path references a specific Stripe invoice ID (164), which may be a demo or placeholder rather than a general-purpose API","The platform lists many endpoints on its homepage but none have documented schemas or usage examples"],"endpointUrl":"https://lowpaymentfee.com/api/v1/stripe/invoices/164","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/164","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 challenge with clear pricing, but there is zero documentation on request parameters, response schema, or what the endpoint actually does beyond the label 'Premium API Access'.
