x402-gated Stripe customer data endpoint on Base, paid per-call in USDC.
What it does
This endpoint at lowpaymentfee.com exposes a specific Stripe customer resource (`/api/v1/stripe/customers/197`) 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 maximum amount required per call is 20,000 base units of USDC, which at 6 decimals equals $0.02 USD.
The broader lowpaymentfee.com platform advertises a wide catalog of pay-per-call APIs spanning data analytics, AI/ML inference (sentiment analysis, summarization, classification, embeddings), finance/crypto market data, and utility services — all priced at $0.02 per request with no API keys, no rate limits, and no commitments. However, the specific endpoint being listed here (`/stripe/customers/197`) is not featured in the site's public catalog; it appears to be a Stripe customer record lookup rather than one of the advertised general-purpose APIs.
Documentation is extremely sparse. The /docs, /pricing, /api, and /README pages all render only a "Connect wallet" prompt with no further content. There is no OpenAPI spec, no request/response schema beyond the x402 challenge's `outputSchema` stub, and no examples of what the endpoint actually returns. The endpoint is confirmed live (402 challenge captured), but the actual data payload and required POST body are unknown.

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base), but there is no documentation, no request/response schema, no examples, and the specific endpoint (/stripe/customers/197) is not listed in the site's own catalog. Effectively a stub listing.
