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 payment wall. It is part of a broader platform offering dozens of pay-per-call APIs spanning data analytics, AI/ML inference, finance/Web3 data, and infrastructure utilities — all priced at $0.02 per request, settled in USDC on the Base network.
The specific endpoint `/api/v1/stripe/charges/120` appears to be in the Finance/Web3 or Infrastructure category, likely related to Stripe charge data or operations (the path suggests a charge resource with ID 120). The x402 challenge confirms the endpoint is live, accepting POST requests, and requiring an exact payment of 20,000 base units of USDC (0x8335…) on Base — which equals $0.02 (USDC uses 6 decimals). Payment is sent to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 with a 300-second timeout.
Documentation is extremely sparse. The landing page lists available APIs and pricing but provides no request/response schemas, parameter descriptions, or usage examples. The /docs, /api, /pricing, and /README pages all returned only a "Connect wallet" prompt with no substantive content. Without documentation or an OpenAPI spec, the exact input parameters and response format for this endpoint remain unknown. The platform advertises no API keys, no rate limits, and instant access — payment via x402 is the sole authentication mechanism.

Quality
The endpoint is confirmed live via a valid x402 402 challenge with clear pricing ($0.02 USDC on Base). However, there is no OpenAPI spec, no request/response schema, no documentation beyond a landing page listing, and no examples. The actual functionality of the '/stripe/charges/120' path is unclear — it could be a demo or placeholder. Effectively a stub listing.
Warnings

- —The endpoint path '/api/v1/stripe/charges/120' suggests a specific charge resource but its purpose (read vs. create, demo vs. production) is unclear
