x402-gated Stripe charges endpoint on Base, pay $0.02 per request in USDC.
What it does
This endpoint at lowpaymentfee.com provides "Premium API Access" behind an x402 paywall. 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.
The 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.
Documentation 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.

Quality
The endpoint is live and returns a valid x402 challenge with clear pricing ($0.02 USDC on Base). However, there is no OpenAPI schema, no request/response examples, and no meaningful documentation — every docs page just shows 'Connect wallet'. The actual functionality of the /stripe/charges/173 endpoint is opaque.
