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 183). 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 micropayments on the Base network using USDC.
The specific endpoint `/api/v1/stripe/customers/183` is listed as "Premium API Access" and accepts POST requests. Payment is settled on-chain via USDC (contract 0x8335…2913) on Base, with a maximum amount of 20,000 base units (i.e., $0.02 given USDC's 6 decimals). The platform advertises no API keys, no rate limits, and instant access — you simply attach an X-PAYMENT header with a valid x402 payment proof.
Documentation is extremely sparse: the /docs, /pricing, /api, and /README pages all render only a "Connect wallet" prompt with no further content. There is no OpenAPI spec, no request/response schema beyond the x402 challenge's outputSchema stub, and no explanation of what data this particular Stripe customer endpoint actually returns. The platform appears to be a demonstration or early-stage deployment of x402-gated APIs with uniform $0.02 pricing across all endpoints.

Quality
The endpoint is live (returns a valid x402 402 challenge) and pricing is clear ($0.02 USDC on Base). However, there is no OpenAPI spec, no request/response schema, no documentation beyond a wallet-connect prompt, and no explanation of what the endpoint actually returns. The listing is essentially a stub with only the x402 challenge to go on.
Warnings

- —Purpose of the Stripe customer endpoint (ID 183) is unclear — may be a demo or placeholder
