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 103) behind an x402 paywall. It accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x8335…2913) via the x402 "exact" scheme.
The endpoint charges a maximum of 20,000 base units of USDC per request. Since USDC uses 6 decimals, this equates to $0.02 per call — consistent with the provider's site-wide flat pricing of $0.02/request. The provider advertises no API keys, no rate limits, and instant access. The x402 challenge specifies a 300-second payment timeout.
The broader lowpaymentfee.com platform hosts a variety of x402-gated APIs spanning data analytics, AI/ML inference, finance/Web3 data, and utility services, all at the same $0.02/request price point. However, this specific endpoint (/api/v1/stripe/customers/103) is not listed among the publicly advertised APIs on the homepage, and its exact response schema is undocumented. The endpoint title "Premium API Access" and the path suggest it returns Stripe customer data, but the precise fields and behavior are unverified beyond the x402 challenge metadata.

Quality
The x402 challenge is live and well-formed, confirming the endpoint exists and accepts payment. However, there is no documentation for this specific endpoint's request/response schema, no OpenAPI spec, and the endpoint path (stripe/customers/103) is not listed among the provider's advertised APIs. The crawled docs/pricing/README pages returned only 'Connect wallet' with no useful content.
