x402-gated Stripe charges endpoint on Base, paying $0.02 in USDC per request.
What it does
This endpoint at lowpaymentfee.com provides "Premium API Access" behind an x402 payment wall. It is part of a broader platform offering pay-per-request APIs across categories including data analytics, AI/ML inference, finance/Web3, and infrastructure utilities — all priced at $0.02 per call settled in USDC on the Base network.
The specific endpoint `/api/v1/stripe/charges/175` appears to be a Stripe charges lookup or proxy. The x402 challenge confirms the endpoint is live, accepting POST requests, and requires an exact payment of 20,000 base units of USDC (0x8335…2913 on Base, 6 decimals = $0.02) to wallet 0x1A2B…85F3. No API keys or rate limits are advertised; access is gated purely by the x402 micropayment.
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 usage examples. The endpoint's exact functionality (what fields it accepts, what it returns) must be inferred from the URL path alone. The platform markets itself on simplicity — no API keys, no rate limits, instant access — but the lack of documentation makes it difficult to evaluate the actual utility of this specific endpoint.

Quality
The endpoint is live (402 challenge confirmed) and pricing is clear ($0.02 USDC on Base), but there is zero documentation on request/response schemas, no OpenAPI spec, and all doc pages render only 'Connect wallet'. The specific purpose of the /stripe/charges/175 endpoint is unclear beyond the URL path.

- —No OpenAPI or schema definition for request or response payloads
- —Exact functionality of /api/v1/stripe/charges/175 is unknown; the path suggests a Stripe charges resource but details are unverifiable
