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 112). It is part of a broader platform that offers dozens of pay-per-call API endpoints 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/112` is listed as "Premium API Access" and accepts POST requests. The x402 challenge advertises a maximum amount of 20,000 base units of USDC (0x8335…2913 on Base), which equals $0.02 USD (USDC uses 6 decimals). Payment is sent to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 with a timeout of 300 seconds. 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 further content. There is no OpenAPI schema, no request/response examples, and no description of what data the Stripe customer endpoint actually returns. The platform's landing page confirms the $0.02/request pricing and lists many other endpoints, but provides no technical detail about request formats or response payloads for any of them.

Quality
The endpoint is live and returns a valid x402 challenge with clear pricing, but there is zero documentation on request format, response schema, or what data is actually returned. The docs/pricing/README pages are all blank beyond a wallet-connect prompt. The endpoint path suggests Stripe customer data but this is unverifiable.
Warnings
- —No OpenAPI schema or request/response documentation available
- —Docs, pricing, and README pages render only 'Connect wallet' with no content
- —The purpose and response format of /api/v1/stripe/customers/112 is unclear — it may return Stripe customer data or something else entirely
- —Only a single customer ID (112) is exposed; unclear if other IDs are accessible
