x402-gated Stripe customer endpoint on Base, paying per-call in USDC.
What it does
This endpoint at lowpaymentfee.com exposes a specific Stripe customer resource (`/api/v1/stripe/customers/41`) behind an x402 paywall. It accepts POST requests and charges up to $0.02 per call in USDC on the Base network. Payment is handled via the x402 protocol's "exact" scheme — callers include an X-PAYMENT header with a signed payment authorization, and the endpoint returns a JSON response upon successful settlement.
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/crypto market data, and utility services (geocoding, validation, conversion). All endpoints share the same $0.02/request pricing model with no API keys, no rate limits, and no minimum commitments. Settlement occurs on the Base L2 network using USDC (contract 0x8335…2913).
However, the specific endpoint being listed here (`/api/v1/stripe/customers/41`) does not appear in the platform's public API catalog and its exact functionality is unclear. The description simply reads "Premium API Access." Documentation pages (/docs, /pricing, /README) all render only a wallet-connect prompt with no substantive content. Without further documentation or example responses, the actual data returned by this endpoint remains unknown.

Quality
The endpoint is live (402 challenge captured) and pricing is clear ($0.02 USDC on Base), but this specific resource (/api/v1/stripe/customers/41) is not documented anywhere on the site. All doc pages render only a wallet-connect prompt. No request/response schema, no examples, and the purpose of this particular endpoint is ambiguous.
