What it does

This endpoint at lowpaymentfee.com provides premium API access to a Stripe invoices resource (invoice #163) via the x402 payment protocol. It accepts POST requests and settles payments in USDC on the Base network. The cost per request is 20,000 base units of USDC (6 decimals), which equals $0.02 per call.

The provider operates a broader platform offering multiple pay-per-call APIs across categories including data & analytics, AI & machine learning, finance & Web3, and infrastructure utilities — all priced at $0.02 per request. The platform advertises no API keys, no rate limits, and instant access. Payments are made via the x402 protocol's X-PAYMENT header using USDC on Base.

The specific endpoint `/api/v1/stripe/invoices/163` appears to be a Stripe invoice-related resource, though the exact response payload and functionality are not documented beyond the generic "Premium API Access" label. No OpenAPI schema, detailed documentation, or example responses were available from the crawled pages (most pages only showed a "Connect wallet" prompt).
