x402-gated Stripe subscription endpoint on Base, paid per-call in USDC.
What it does
This endpoint at lowpaymentfee.com provides a "Premium API Access" resource gated behind the x402 payment protocol. It is part of a broader platform that offers a variety of pay-per-request APIs spanning data analytics, AI/ML inference, finance/Web3 data, and utility services — all settled on the Base network using USDC.
The specific endpoint `/api/v1/stripe/subscriptions/180` appears to be a Stripe subscription-related resource. The x402 challenge confirms it is live and accepts POST requests. The maximum amount required is 20,000 base units of USDC (0x8335… on Base), which equals $0.02 USD (USDC uses 6 decimals). Payment is made via the x402 "exact" scheme to the specified wallet address, with a 300-second timeout window.
The platform advertises a uniform $0.02-per-request pricing model across all its endpoints, with no API keys, no rate limits, and instant access. However, documentation is extremely sparse — the docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no substantive content. There is no OpenAPI schema, no request/response examples, and no detailed description of what this particular subscription endpoint returns or expects as input. The endpoint's actual functionality (whether it creates, retrieves, or manages Stripe subscriptions) is unclear from the available material.

Quality
The x402 challenge is live and confirms pricing and payment details, but there is zero documentation on what this endpoint actually does, what input it expects, or what it returns. No OpenAPI schema, no examples, and all doc pages are empty beyond a wallet-connect prompt. The endpoint's purpose (Stripe subscriptions) is only inferable from the URL path.

- —The specific functionality of /api/v1/stripe/subscriptions/180 is unclear — it may create, retrieve, or manage subscriptions but this is not documented
- —Platform appears to be a demonstration or early-stage project with many listed endpoints but no substantive documentation
