x402-gated Stripe customer data endpoint on Base, paid per-call in USDC.
What it does
This endpoint at lowpaymentfee.com provides access to a specific Stripe customer resource (customer ID 101) 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 specific endpoint `/api/v1/stripe/customers/101` is listed as "Premium API Access" and costs up to 20,000 base units of USDC (i.e., $0.02 given USDC's 6 decimals). The broader lowpaymentfee.com platform advertises a wide 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 required.
However, the actual behavior and response schema of this particular Stripe customer endpoint are undocumented. The crawled docs, pricing, and README pages all returned only a "Connect wallet" prompt with no further content. There is no OpenAPI spec, no example responses, and no description of what data fields are returned. The endpoint is confirmed live (402 challenge captured), but the lack of documentation makes it difficult to know exactly what payload to send or what response to expect.

Quality
The endpoint is confirmed live with a valid x402 402 challenge, but there is no OpenAPI spec, no documented request/response schema, no example payloads, and the docs pages are empty. The purpose of a 'Stripe customers/101' endpoint on a third-party domain is unclear and undocumented.
