x402-gated Stripe customer data endpoint on Base, paid per-request in USDC.
What it does
This endpoint at lowpaymentfee.com provides access to a specific Stripe customer resource (customer ID 148) behind an x402 paywall. The endpoint accepts POST requests and returns JSON. Payment is settled on the Base network using USDC (contract 0x8335…2913) via the x402 "exact" scheme. The maximum amount required per call is 20,000 base units of USDC, which equals $0.02 (USDC uses 6 decimals).
The hosting provider, lowpaymentfee.com, offers a broader catalog of x402-gated APIs spanning data analytics, AI/ML inference (sentiment analysis, summarization, classification, embeddings), finance/crypto market data, and infrastructure utilities — all priced at $0.02 per request with no API keys, no rate limits, and no commitments. However, this specific endpoint (/api/v1/stripe/customers/148) is not listed on the provider's public catalog and appears to expose Stripe customer data, which is unusual for a public pay-per-call API.
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 spec, no request/response schema documentation, and no description of what fields are returned for this Stripe customer endpoint. The endpoint is confirmed live (returns a valid x402 402 challenge), but the actual behavior after payment is unknown.

Quality
The endpoint is live and returns a valid x402 challenge, but there is no documentation, no OpenAPI spec, no request/response schema, and no explanation of what data is returned. The endpoint exposes a single Stripe customer record which is not listed in the provider's own catalog. Effectively a stub listing.
Warnings
- —This endpoint is not listed in the provider's own public API catalog — it may be a test or internal resource.
- —Exposing Stripe customer data via a public pay-per-call endpoint raises data privacy concerns.
- —No documentation exists: /docs, /api, /pricing, and /README all show only a wallet-connect prompt.
- —No request or response schema is available; actual payload structure is unknown.
- —The endpoint targets a single hardcoded customer ID (148), limiting general utility.
