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 77) via a POST request. 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/77` is labeled "Premium API Access" by the provider. The x402 challenge advertises a maximum cost of 20,000 base units of USDC (0x8335…2913 on Base), which equals $0.02 per request (USDC uses 6 decimals). Payment is made via the x402 "exact" scheme to the provider's wallet. No API keys are required; authentication is handled entirely through the x402 payment header. The provider claims 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 substantive content. There is no OpenAPI schema, no request/response examples, and no description of what data this endpoint actually returns about the Stripe customer. The endpoint is confirmed live (returns a proper 402 challenge), but the lack of documentation makes it difficult to know what payload to send or what response to expect.

Quality
The endpoint is confirmed live with a valid x402 402 challenge and clear pricing ($0.02 USDC on Base). However, documentation is essentially nonexistent — all doc pages show only 'Connect wallet'. There is no OpenAPI schema, no request/response examples, and no explanation of what the endpoint actually returns. The purpose of accessing a specific Stripe customer by ID via a public paid API is unclear.
Warnings
- —No documentation available — all doc/pricing/API pages render only 'Connect wallet'
- —No OpenAPI or output schema provided; request body format and response structure are unknown
- —The purpose of exposing a single Stripe customer record (ID 77) as a paid API is unclear and may be a demo or placeholder
- —No information on what data is returned or what POST body is expected
