x402-gated Stripe charges endpoint on Base, pay $0.02 per request in USDC.
What it does
This endpoint at lowpaymentfee.com provides "Premium API Access" behind an x402 paywall. It is part of a broader platform offering dozens of pay-per-call API endpoints spanning data analytics, AI/ML inference, finance/Web3 data, and utility services — all priced at $0.02 per request, settled in USDC on the Base network.
The specific endpoint `/api/v1/stripe/charges/195` appears to be related to Stripe charge operations, though the crawled documentation is extremely thin and provides no details on request/response schemas, parameters, or what data this particular endpoint returns. The platform advertises no API keys, no rate limits, and instant access via x402 payment headers. The x402 challenge was successfully captured, confirming the endpoint is live and accepting POST requests with USDC payments on Base (asset 0x8335…2913, which is the canonical Base USDC contract).
The maximum amount required per call is 20,000 base units of USDC (6 decimals), which equals $0.02 — consistent with the site's advertised pricing. Payment is sent to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 with a 300-second timeout. No OpenAPI spec, detailed docs, or example payloads were found; the docs, pricing, API, and README pages all render only a "Connect wallet" prompt with no substantive content.

Quality
The endpoint is live and returns a valid x402 challenge, but there is essentially no documentation: no OpenAPI spec, no request/response schema, no examples, and no explanation of what this specific endpoint does. The docs pages are empty (wallet-connect only). This is effectively a stub listing.
