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 38). It is part of a broader platform that offers a variety of pay-per-call APIs spanning data analytics, AI/ML inference, finance/Web3 data, and infrastructure utilities — all gated behind x402 payment challenges settled in USDC on the Base network.
The specific endpoint `/api/v1/stripe/customers/38` is labeled "Premium API Access" and accepts HTTP POST requests. The x402 challenge advertises a maximum cost of 20,000 base units of USDC (0x8335… on Base), which equals $0.02 per request (USDC uses 6 decimals). Payment is sent to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 using the "exact" payment scheme. The endpoint has a 300-second payment timeout.
The platform's landing page advertises a flat $0.02/request pricing model across all endpoints with no API keys, no rate limits, no minimums, and instant access. Documentation pages (/docs, /pricing, /README) appear to require wallet connection and contain no substantive content in the crawl. Because the endpoint path references a Stripe customer resource, the actual response payload likely returns customer-related data, but no response schema or example is documented.

Quality
The endpoint is live and returns a valid x402 402 challenge with clear pricing. However, there is no OpenAPI schema, no response examples, and the documentation pages are empty (wallet-gated). The purpose of this specific Stripe customer endpoint is unclear beyond its title.

- —Documentation pages (/docs, /pricing, /README) are wallet-gated and contain no crawlable content
- —The endpoint path suggests access to a specific Stripe customer record (ID 38) — unclear what data is returned or whether the body requires input parameters
- —No OpenAPI specification available
