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 165) 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 (USDC uses 6 decimals).
The hosting provider lowpaymentfee.com advertises a broad catalog of pay-per-call 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/165) is not listed among the publicly advertised APIs on the landing page. Its path suggests it returns Stripe customer information for a particular customer record, but no documentation, request schema, or response schema is available beyond the x402 challenge metadata.
Because no OpenAPI spec, usage examples, or detailed docs were found (the /docs, /api, /pricing, and /README pages all returned only a "Connect wallet" prompt with no substantive content), the actual behavior and response format of this endpoint remain unclear. Prospective callers should be aware that they are paying $0.02 in USDC on Base per request with no documented guarantee of what the response contains.

Quality
The endpoint is live (returns a valid x402 402 challenge), but there is no OpenAPI spec, no request/response schema, no documentation beyond a wallet-connect prompt, and the specific endpoint path is not listed in the provider's public catalog. The purpose and output of this endpoint are largely opaque.
