x402-gated Stripe customer endpoint on Base, pay-per-call with USDC.
What it does
This endpoint at lowpaymentfee.com provides access to a Stripe customer resource (customer ID 138) behind an x402 paywall. It is part of a broader platform that offers dozens of pay-per-request API endpoints spanning data analytics, AI/ML inference, finance, crypto, and utility services — all settled on the Base network using USDC.
The specific endpoint `/api/v1/stripe/customers/138` accepts POST requests and is priced at a maximum of $0.02 per call (20,000 base units of USDC with 6 decimals). Payment is made via the x402 exact scheme to the wallet address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 on Base. 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 substantive content. There is no OpenAPI schema, no request/response examples, and no description of what data this Stripe customer endpoint actually returns or what POST body it expects. The endpoint is confirmed live (returns a proper 402 challenge), but the lack of documentation makes it difficult to use without experimentation.

Quality
The endpoint is confirmed live with a valid x402 402 challenge, but documentation is essentially nonexistent — all doc pages show only 'Connect wallet'. There is no OpenAPI spec, no request/response schema, no examples, and no explanation of what the Stripe customer endpoint actually returns. The listing is effectively a stub.
Warnings
- —No documentation available — all doc/API/pricing/README pages render only 'Connect wallet'
- —No OpenAPI or request/response schema provided
- —Purpose of the Stripe customer endpoint is unclear — it may expose sensitive payment data
- —No information on what POST body is expected
- —The endpoint path references a specific customer ID (138), which may indicate a demo or test resource rather than a general-purpose API
