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/173`) 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 equals $0.02 (USDC uses 6 decimals).
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, this specific listing is for the Stripe customers endpoint, whose exact response payload is undocumented. No OpenAPI spec, detailed docs, or example responses were found during the crawl; most documentation pages returned only a "Connect wallet" prompt.
Because the endpoint returned a well-formed 402 challenge with x402 version 1, it is confirmed live. The payment address is 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 with a 300-second timeout. Without documentation or sample responses, the exact shape of the returned Stripe customer data is unknown.
