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 137) 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 provider, lowpaymentfee.com, hosts a broader catalog of x402-gated APIs spanning data & analytics, AI/ML inference, finance/Web3, and infrastructure utilities — all priced at $0.02 per request with no API keys, no rate limits, and no minimum commitments. However, this specific listing is for the Stripe customers endpoint at `/api/v1/stripe/customers/137`, which is not listed on the provider's public landing page among the advertised API categories. The exact response payload and input parameters are undocumented; the output schema only specifies that it is an HTTP POST endpoint returning `application/json`.
Because there is no OpenAPI spec, no request/response examples, and no documentation beyond the x402 challenge itself, the precise data returned by this endpoint is unknown. The endpoint is confirmed live (returns a valid 402 challenge). Callers should be aware that the Stripe customer resource path suggests this may return customer-level billing or subscription data, but this is speculative given the lack of documentation.

Quality
