Pay-per-call Stripe customer data endpoint on Base via x402, settled in USDC at $0.02/request.
What it does
This x402-enabled endpoint at lowpaymentfee.com provides access to Stripe customer data (specifically customer ID 1) via a POST request. Payment is settled on the Base network using USDC (contract 0x8335…2913) through the x402 exact-payment scheme. The maximum amount required per call is 20,000 base units of USDC (6 decimals), which equals $0.02 USD per request.
The provider's landing page advertises a broad catalog of pay-per-call APIs spanning data & analytics, AI/ML (sentiment analysis, summarization, classification, embeddings), finance & Web3 (price feeds, exchange rates, token quotes, gas estimates), and infrastructure utilities (geocoding, validation, conversion, generation) — all priced at $0.02 per request. However, this specific endpoint targets Stripe customer data retrieval. No API keys or rate limits are advertised; access is gated purely by the x402 payment challenge.
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 the endpoint returns. The endpoint is confirmed live (returns a proper 402 challenge), but the actual behavior and response format remain unknown.

Quality
The endpoint is live and returns a valid x402 challenge with clear pricing, but documentation is effectively nonexistent — every doc page shows only 'Connect wallet'. There is no OpenAPI schema, no request/response examples, and no explanation of what data the endpoint actually returns. The specific endpoint path (/stripe/customers/1) is not even listed on the landing page catalog.
Warnings
- —Documentation pages (/docs, /api, /pricing, /README) contain no substantive content — only a 'Connect wallet' prompt.

- —This specific endpoint (/api/v1/stripe/customers/1) is not listed in the provider's advertised API catalog on the landing page.
- —The hardcoded customer ID '1' in the URL suggests this may be a demo or placeholder endpoint rather than a general-purpose API.
