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 Stripe customer resource (customer ID 99) behind an x402 payment wall. 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 broader lowpaymentfee.com platform advertises a suite of pay-per-request APIs spanning data analytics, AI/ML inference (sentiment analysis, summarization, classification, embeddings), finance and crypto market data, and infrastructure utilities—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, and the crawled documentation pages returned only a "Connect wallet" prompt with no further technical detail.
Because there is no OpenAPI schema, no request/response examples, and no documentation beyond the landing page summary, the actual behavior of this endpoint—what fields it expects in a POST body and what it returns—remains unclear. The endpoint is confirmed live (402 challenge captured), but users should expect to experiment or contact the provider for integration details.
