It is part of a broader platform offering dozens of pay-per-call APIs spanning data analytics, AI/ML inference, finance/Web3, and infrastructure utilities — all priced at $0.02 per request and settled in USDC on the Base network.\n\nThe specific endpoint `/api/v1/stripe/charges/173` appears to be a Stripe charges resource. The x402 challenge confirms it accepts POST requests and requires an exact payment of 20,000 base units of USDC (0x8335…2913 on Base), which equals $0.02 given USDC's 6 decimals. Payment is sent to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 with a 300-second timeout. No API keys or rate limits are advertised; access is granted purely through the x402 payment header.\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 detailed description of what the `/stripe/charges/173` endpoint actually returns or what parameters it accepts. The platform's landing page lists many endpoints but provides no technical documentation for any of them. As a result, the actual functionality behind this specific endpoint is unclear beyond its name.","tags":[],"capabilities":["x402-payment","usdc-base","pay-per-request","stripe-charges","post-method"],"categories":["finance","infrastructure"],"synonyms":["stripe charges API","x402 payment endpoint","USDC micropayment API","pay-per-call API","lowpaymentfee","Base network API","crypto payment gateway"],"warnings":["No documentation available — all doc pages render only 'Connect wallet'","No OpenAPI or request/response schema provided","Unclear what data or action the /api/v1/stripe/charges/173 endpoint actually provides","The endpoint name suggests Stripe charge data but no details confirm this"],"endpointUrl":"https://lowpaymentfee.com/api/v1/stripe/charges/173","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/charges/173","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 ($0.02 USDC on Base).
