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 119) 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 hosting site lowpaymentfee.com advertises a broad catalog of pay-per-call APIs spanning data analytics, AI/ML inference, finance/Web3 data, and utility services — all priced at $0.02 per request with no API keys, no rate limits, and no commitments. However, this particular endpoint's x402 challenge specifies a maxAmountRequired of 20,000 base units of USDC (6 decimals), which equals $0.02 USD, consistent with the site's advertised pricing.
The endpoint is live and returns a proper x402 challenge (version 1) when called without payment. Documentation on the site is extremely thin — the /docs, /pricing, /api, and /README pages all render only a "Connect wallet" prompt with no further technical detail. There is no OpenAPI spec, no request/response schema documentation, and no explanation of what data the Stripe customers endpoint actually returns or what POST body it expects. The endpoint path suggests it retrieves or manipulates a Stripe customer record, but the exact behavior, required input fields, and response format are unknown.

Quality
The endpoint is live and returns a valid x402 challenge, but there is zero documentation on request format, response schema, or what the endpoint actually does beyond the path hint. No OpenAPI spec, no examples, and all doc pages are empty wallet-connect stubs.

- —No OpenAPI or schema definition for request or response bodies
- —Endpoint purpose is inferred solely from URL path; actual behavior is unverified
