x402-gated Stripe customer endpoint on Base, pay $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 97). It is part of a broader platform offering dozens of pay-per-call API endpoints across data analytics, AI/ML inference, finance/Web3, and infrastructure utilities — all gated behind x402 payment challenges on the Base network using USDC.
The specific endpoint `/api/v1/stripe/customers/97` is labeled "Premium API Access" and accepts 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 with a 300-second timeout. The platform advertises no API keys, no rate limits, and instant access.
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 spec, no request/response schema documentation, and no examples of what the endpoint actually returns. The endpoint's purpose (retrieving or interacting with a Stripe customer record) can only be inferred from the URL path. The broader platform lists many endpoints but provides no detail on request parameters or response formats for any of them.

Quality
The endpoint is live (returns a valid x402 402 challenge) and pricing is clear at $0.02/request in USDC on Base. However, there is no OpenAPI spec, no request/response schema, no documentation beyond a wallet-connect prompt, and no examples. The actual purpose of the endpoint (what data it returns for a Stripe customer) is entirely unclear from available material.
