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 153). It is part of a broader platform offering 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/153` is labeled "Premium API Access" and accepts POST requests. 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 sent to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 with a 300-second timeout. No API keys or rate limits are advertised; access is purely payment-gated.
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 schema, no request/response examples, and no description of what data the Stripe customer endpoint actually returns. The platform's landing page lists many endpoints at $0.02 each across categories like sentiment analysis, text summarization, geocoding, and crypto gas estimates, but provides no technical detail about request formats or response payloads for any of them.

Quality
The endpoint is live and returns a valid x402 challenge with clear pricing ($0.02 USDC on Base). However, there is no OpenAPI schema, no request/response examples, no documentation beyond a wallet-connect prompt, and the purpose of a 'Stripe customers/153' endpoint is unclear. Effectively a stub listing.
Warnings
- —No documentation available — docs, API, pricing, and README pages all show only 'Connect wallet'
- —No OpenAPI or request/response schema provided
- —Purpose of the /api/v1/stripe/customers/153 endpoint is unclear — it may expose third-party Stripe customer data, raising potential privacy concerns
- —No information on what POST body is expected or what the response contains
- —The endpoint targets a single hardcoded customer ID (153); unclear if other IDs are accessible
