x402-gated Stripe customer data endpoint on Base, paid per-call in USDC.
What it does
This endpoint at lowpaymentfee.com provides access to a specific Stripe customer resource (customer ID 180) behind an x402 paywall. It accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x8335…2913) via the x402 "exact" scheme.
The endpoint charges a maximum of 20,000 base units of USDC per request. Since USDC uses 6 decimals, this equals $0.02 per call — consistent with the provider's site-wide flat pricing of $0.02/request. The provider advertises no API keys, no rate limits, and instant access; the only gate is the x402 payment header.
The broader lowpaymentfee.com platform lists many additional endpoints across data/analytics, AI/ML, finance/Web3, and infrastructure categories, all at the same $0.02/request price point. However, this specific listing covers only the `/api/v1/stripe/customers/180` resource. Documentation on the site is extremely thin — the docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no further technical detail. There is no OpenAPI spec, no request/response schema documentation, and no explanation of what data the Stripe customer endpoint actually returns.

Quality
The endpoint is live (returns a valid x402 402 challenge), but there is virtually no documentation: no OpenAPI spec, no request/response schema, no explanation of what data is returned. The docs pages are empty beyond a wallet-connect prompt. The endpoint path suggests Stripe customer data but this is unverified. Pricing is clear at $0.02/call.
Warnings
- —No API documentation available — docs, API, pricing, and README pages all show only 'Connect wallet' with no content.
- —No request or response schema is documented; callers cannot know what fields to send or expect back.
- —The endpoint targets a hardcoded customer ID (180); it is unclear whether this is a demo or production resource.
- —The nature of the returned Stripe customer data is completely undocumented.
