Pay-per-call Azure integration endpoint via x402 on Base, settling in USDC at $0.02/request.
What it does
This x402-enabled endpoint at lowpaymentfee.com provides a "Premium API Access" integration with Azure, accessible at `/api/v1/integrations/azure/secret`. It uses the x402 payment protocol on the Base network, accepting USDC (USD Coin) payments. The endpoint is live and returns a standard 402 challenge when called without payment.
The specific endpoint listed here is part of a broader platform (lowpaymentfee.com) that offers numerous pay-per-call APIs across categories including data & analytics, AI & machine learning, finance & Web3, and infrastructure utilities. All endpoints on the platform are advertised at $0.02 per request with no API keys, no rate limits, and no commitments required. The x402 challenge for this particular endpoint shows a maxAmountRequired of 20000 base units of USDC (6 decimals), which equals $0.02.
However, the exact functionality of the `/api/v1/integrations/azure/secret` endpoint is unclear. The name suggests it may proxy or retrieve a secret/credential from Azure, but no documentation, request schema, or response schema is provided beyond the generic "Premium API Access" description. The platform's other pages (pricing, README, API docs) all resolve to a minimal "Connect wallet" page with no additional detail. Prospective users should be aware that the actual behavior of this endpoint is undocumented.

Quality
The endpoint is live (402 challenge confirmed) and pricing is clear ($0.02/request in USDC on Base), but there is no documentation, no request/response schema, and no explanation of what the endpoint actually does. The 'azure/secret' path is opaque without further context.
Warnings

- —No request or response schema provided
- —Platform docs pages (pricing, README, API) all resolve to a minimal 'Connect wallet' page with no useful content
