Azure token endpoint via x402 micropayment on Base — $0.02 per request in USDC.
What it does
This endpoint at lowpaymentfee.com provides a "Premium API Access" resource at `/api/v1/integrations/azure/token`, settled via the x402 protocol on the Base network using USDC. The x402 challenge confirms the endpoint is live, accepting POST requests with a maximum cost of 20,000 base units of USDC (0.02 USD per call). The provider describes it as part of a broader platform offering data & analytics, AI/ML inference, finance/Web3, and infrastructure utility APIs, all priced uniformly at $0.02 per request.
The specific functionality of this particular endpoint — `/api/v1/integrations/azure/token` — is not documented beyond the label "Premium API Access." Based on the path, it likely proxies or brokers an Azure service token (e.g., an Azure OpenAI or Azure Cognitive Services access token), but this is inference from the URL structure alone. No OpenAPI schema, request/response examples, or detailed documentation were found in the crawl. The provider's landing page lists many other endpoints but does not mention this one explicitly.
Payment is keyless: callers pay per request via an x402 `X-PAYMENT` header carrying a signed USDC transaction on Base (chain). There are no API keys, no rate limits, and no subscription commitments according to the provider's homepage. The payment address is `0x1A2B…85F3` and the USDC asset contract is `0x8335…2913` (canonical Base USDC). Timeout for payment settlement is 300 seconds.

Quality
The x402 challenge is live and confirms pricing and network details, but there is no documentation, no OpenAPI schema, no request/response examples, and the actual functionality of the endpoint is only inferable from the URL path. Effectively a stub listing.
