Market quote for MMC token via x402 micropayment on Base, $0.02 per request.
What it does
This endpoint at lowpaymentfee.com provides a market quote for the MMC token (or asset identified as "MMC") via a POST request. It is part of a broader platform offering data, analytics, AI, finance, and infrastructure APIs, all gated behind the x402 payment protocol on the Base network. Each call costs $0.02 in USDC, paid per-request with no API keys, rate limits, or subscriptions required.
The x402 challenge confirms the endpoint is live, accepting payments in USDC (contract 0x8335…2913 on Base) with an exact-scheme payment of 20,000 base units (i.e., $0.02 given USDC's 6 decimals). The payment is sent to address 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3 with a 300-second timeout. The response MIME type is application/json.
Documentation beyond the landing page is extremely sparse — the /docs, /api, /pricing, and /README pages all render only a "Connect wallet" prompt with no additional technical detail. There is no OpenAPI spec, no request/response schema, and no example payloads available. The exact structure of the MMC quote response and what request body parameters are accepted (if any) are unknown. The endpoint path suggests it returns a market price quote for a token or commodity identified as "MMC," but this cannot be confirmed from available materials.
