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 API endpoints spanning data analytics, AI/ML inference, finance/Web3 data, and infrastructure utilities — all priced at $0.02 per request, settled in USDC on the Base network.
The specific endpoint `/api/v1/stripe/charges/190` appears to be in the Stripe charges category, though the platform's landing page does not list it among its publicly advertised APIs. The x402 challenge confirms it is live and accepts POST requests. Payment is made via the x402 "exact" scheme to address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` using USDC (contract `0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913`) on Base. The maxAmountRequired is 20000 base units, which equals $0.02 (USDC has 6 decimals). The timeout is 300 seconds.
Documentation is extremely sparse. The docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no additional content. There is no OpenAPI spec, no request/response schema, and no explanation of what this particular endpoint 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 endpoint is undocumented.

Quality
The endpoint is live (402 challenge confirmed) and pricing is clear ($0.02 USDC on Base), but there is zero documentation on request parameters, response schema, or what this endpoint actually does. No OpenAPI spec, no examples, and the docs pages are empty. The endpoint path suggests Stripe charge operations but this is unverified.
