x402-gated Stripe customer data endpoint on Base, paid per-request in USDC.
What it does
This endpoint at lowpaymentfee.com provides access to a specific Stripe customer resource (customer ID 194) behind an x402 paywall. The endpoint accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x8335…2913) via the x402 "exact" scheme. The maximum amount required per call is 20,000 base units of USDC, which equals $0.02 USD (USDC uses 6 decimals).
The hosting provider, lowpaymentfee.com, advertises a broad catalog of x402-gated APIs spanning data analytics, AI/ML inference, finance/Web3 data, and infrastructure utilities — all priced at $0.02 per request with no API keys, no rate limits, and no commitments. However, this specific endpoint (/api/v1/stripe/customers/194) is not listed among the publicly advertised APIs on the landing page. Its path suggests it returns Stripe customer data for a particular customer record, but there is no documentation, schema, or example response available to confirm what the response payload contains.
Because the endpoint is live (returning a valid 402 challenge) but lacks any documentation beyond the generic "Premium API Access" label, the actual utility and response format remain unclear. Users should treat this as an opaque endpoint until further documentation is provided.
