Stock quote data for MMC (Marsh & McLennan) via x402 micropayment on Base, $0.02/request.
What it does
This endpoint provides stock data for the ticker MMC (Marsh & McLennan Companies) through the lowpaymentfee.com platform. It is part of a broader suite of pay-per-call APIs covering data analytics, AI/ML inference, finance, crypto, and utility services. The endpoint uses the x402 payment protocol, settling in USDC on the Base network at $0.02 per request. No API keys, rate limits, or subscriptions are required — callers simply attach an x402 payment header to each POST request.
The specific endpoint `/api/v1/stocks/MMC` sits under the Finance & Web3 category of the provider's API catalog. While the provider lists many endpoints (price feeds, exchange rates, token quotes, gas estimates, etc.), this particular route serves stock-level data for the MMC ticker. The response MIME type is `application/json`. No detailed schema for the response body is documented in the crawled material, so the exact fields returned (e.g., price, volume, change) must be inferred from the finance context.
The provider's landing page confirms a flat $0.02-per-request pricing model across all endpoints, with no minimums or commitments. Payment is made in USDC (contract `0x8335…2913`) on Base. The x402 challenge was successfully captured with `maxAmountRequired` of 20000 base units, which equals $0.02 (USDC uses 6 decimals). The endpoint is live and responding with a proper 402 challenge.
