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 109) 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 USD (USDC uses 6 decimals).
The hosting provider, lowpaymentfee.com, offers a broader catalog of x402-gated APIs spanning data analytics, AI/ML inference, finance/Web3 data, and utility services — 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/109) is not listed on the provider's public catalog page and appears to expose Stripe customer data. The exact response schema is undocumented; no OpenAPI spec, detailed docs, or example responses were found during crawling (docs, pricing, and API pages all returned only a "Connect wallet" prompt).
Because the endpoint is live (returning a valid 402 challenge) but lacks documentation about what data it actually returns, agents should treat this as a low-documentation, potentially niche endpoint. The provider's site confirms the $0.02 pricing model and Base network settlement, but specifics about this particular resource are unclear.

Quality
The endpoint is live and returns a valid x402 challenge with clear pricing ($0.02 USDC on Base). However, there is no OpenAPI spec, no response schema, no example responses, and the docs/pricing/API pages are all gated behind a wallet connection with no useful content. The specific endpoint path (stripe/customers/109) is not listed in the provider's public catalog, making its purpose and output unclear.
