x402-gated Stripe customer endpoint on Base, pay $0.02 per request in USDC.
What it does
This endpoint at lowpaymentfee.com provides x402-protocol access to a Stripe customer resource (`/api/v1/stripe/customers/29`). It is part of a broader platform that offers dozens of pay-per-call API endpoints spanning data analytics, AI/ML inference, finance/Web3 data, and infrastructure utilities — all gated behind x402 payment challenges settled in USDC on the Base network at $0.02 per request.
The specific endpoint probed (`/api/v1/stripe/customers/29`) is labeled "Premium API Access" and returns a valid x402 challenge requesting up to 20,000 base units of USDC (0x8335…2913 on Base, 6 decimals = $0.02). Payment is made via the `exact` scheme to wallet `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3` with a 300-second timeout. The endpoint accepts POST requests and returns `application/json`.
Documentation is extremely sparse — the docs, pricing, API, and README pages all render only a "Connect wallet" prompt with no further content. There is no OpenAPI spec, no request/response schema, and no explanation of what data this particular Stripe customer endpoint actually returns or what POST body it expects. The platform's landing page lists many other endpoints but does not describe this one specifically. Prospective callers should be aware that the actual behavior and response format of this endpoint are undocumented.

Quality
The endpoint is live and returns a valid x402 challenge, but there is zero documentation on what the endpoint does, what request body it expects, or what it returns. No OpenAPI spec, no examples, and the docs/pricing/README pages are all blank beyond a wallet connect prompt. The 'Premium API Access' label and Stripe customer path are the only clues to functionality.
