x402-gated Stripe customer endpoint on Base, pay-per-call with USDC.
What it does
This endpoint at lowpaymentfee.com exposes a Stripe customer resource (`/api/v1/stripe/customers/67`) behind an x402 paywall. When called without payment, it returns a 402 challenge requesting USDC on the Base network. The maximum amount required is 20,000 base units of USDC (0.02 USD per request), settled to the on-chain address `0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3`. The response MIME type is `application/json` and the endpoint accepts HTTP POST.
The broader lowpaymentfee.com platform advertises a catalog of x402-gated APIs spanning data & analytics, AI/ML inference (sentiment analysis, summarization, classification, embeddings), finance & Web3 (price feeds, exchange rates, token quotes, gas estimates), and infrastructure utilities (geocoding, validation, conversion, generation). All endpoints are listed at $0.02 per request with no API keys, no rate limits, and no commitments required.
However, this specific endpoint (`/api/v1/stripe/customers/67`) appears to be a Stripe customer data resource, which is not listed among the publicly advertised API categories. Its exact purpose and response schema are undocumented. The docs, pricing, API, and README pages all render only a "Connect wallet" prompt with no additional documentation. Without schema details or example responses, the actual data returned by this endpoint remains unclear.

Quality
The endpoint is live (402 challenge confirmed) and pricing is clear ($0.02 USDC on Base), but there is no documentation, no request/response schema, and no explanation of what the Stripe customer resource actually returns. The docs pages are empty beyond a wallet-connect prompt. This is effectively a stub listing.
