x402-gated Stripe charges endpoint on Base, pay $0.02 per request in USDC.
What it does
lowpaymentfee.com hosts a collection of x402-protocol pay-per-call API endpoints settled in USDC on the Base network. The specific endpoint at `/api/v1/stripe/charges/1` is listed as "Premium API Access" and accepts POST requests gated by an x402 payment challenge. The price per call is 20,000 base units of USDC (0.02 USD), consistent with the site-wide $0.02/request pricing advertised across all their endpoints.
The provider offers endpoints spanning several categories: data & analytics (metrics, reports, data export, insights), AI & machine learning (sentiment analysis, text summarization, classification, embeddings), finance & Web3 (price feeds, exchange rates, token quotes, gas estimates), and infrastructure utilities (geocoding, validation, conversion, generation). All endpoints share the same $0.02 per-request pricing with no API keys, no rate limits, and no minimum commitments required.
The specific functionality behind the `/api/v1/stripe/charges/1` endpoint is unclear from the available documentation. The name suggests it may relate to Stripe payment/charge data, but no request/response schema, parameter documentation, or usage examples are provided. The docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no substantive content, making it impossible to confirm what data or service this endpoint actually returns.
