What it does

This endpoint at lowpaymentfee.com provides x402-protocol access to a Stripe invoice resource (invoice ID 117). It is part of a broader platform offering pay-per-request APIs across data analytics, AI/ML inference, finance, and utility categories — all gated behind x402 payment challenges settled in USDC on the Base network.

The specific endpoint `/api/v1/stripe/invoices/117` is labeled "Premium API Access" and accepts POST requests. The x402 challenge advertises a maximum cost of 20,000 base units of USDC (0x8335… on Base), which equals $0.02 per request given USDC's 6 decimal places. Payment is sent to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 with a 300-second timeout. No API keys or rate limits are advertised; access is purely payment-gated.

Documentation is extremely sparse. The docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no substantive content. There is no OpenAPI schema, no request/response examples, and no description of what data the invoice endpoint actually returns. The platform's landing page lists many other endpoints (analytics, AI, finance, utilities) at the same $0.02 price point, but none have documented schemas or sample payloads. The endpoint is confirmed live via a valid 402 challenge response.
