x402-gated Stripe customer endpoint on Base, paying $0.02 per request in USDC.
What it does
This endpoint at lowpaymentfee.com provides x402-protocol access to a Stripe customer resource (customer ID 73). It is part of a broader platform offering pay-per-call APIs across data analytics, AI/ML inference, finance, and utility categories — all gated behind x402 payment challenges settled in USDC on the Base network at $0.02 per request.
The specific endpoint `/api/v1/stripe/customers/73` is labeled "Premium API Access" in the x402 challenge. The challenge confirms the endpoint is live, accepts POST requests, and requires an exact payment of 20,000 base units of USDC (0x8335…2913 on Base, 6 decimals = $0.02). Payment is sent to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 with a 300-second timeout. No API keys or rate limits are advertised; access is purely payment-gated.
Documentation is extremely sparse. The docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no additional content. There is no OpenAPI schema, no request/response examples, and no description of what data this endpoint actually returns beyond the generic "Premium API Access" label. The platform lists many other endpoints (analytics, AI, finance, utilities) at the same $0.02 price point, but none have documented schemas or example payloads. Without further documentation it is unclear what request body this POST endpoint expects or what response shape it returns.

Quality
The endpoint is live and returns a valid x402 challenge with clear pricing ($0.02 USDC on Base). However, there is no OpenAPI schema, no request/response examples, and all documentation pages render only 'Connect wallet' with no useful content. The purpose of this specific Stripe customer endpoint is unclear beyond its label.
Warnings
- —No documentation available — docs, API, pricing, and README pages all show only 'Connect wallet'
- —No request body schema or response schema provided
- —Purpose of accessing Stripe customer 73 specifically is unexplained
- —No OpenAPI or ai-plugin manifest found
- —The endpoint path suggests it returns data for a single hardcoded customer ID, which is unusual
