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 156) 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/156) is not listed on the provider's public catalog page, and its purpose — returning Stripe customer data — is distinct from the advertised categories. No OpenAPI schema, detailed documentation, or example responses were found; the docs, pricing, and README pages all returned only a "Connect wallet" prompt with no substantive content.
Because there is no documentation describing the request body format or the response schema for this particular endpoint, agents calling it will need to experiment or rely on the generic x402 payment flow. The endpoint is confirmed live (returns a valid 402 challenge), but the lack of documentation and the unusual resource path (a single Stripe customer record) raise questions about its intended audience and data contents.

Quality
The endpoint is live and returns a valid x402 402 challenge, confirming pricing and network details. However, there is no OpenAPI schema, no documentation, no example requests or responses, and the endpoint is not listed in the provider's own catalog. The specific resource (a single Stripe customer) is opaque without further context.
