Get MCO stock price data via x402 micropayment on Base for $0.02 per request.
What it does
This endpoint returns the current stock price for MCO (Moody's Corporation) via a pay-per-call x402 micropayment model. It is hosted on lowpaymentfee.com, a platform that offers a broad catalog of data, AI, finance, and utility APIs all priced at $0.02 per request, settled in USDC on the Base network.
The endpoint accepts POST requests and returns JSON. Payment is handled through the x402 protocol: callers receive a 402 challenge containing payment details (payTo address, asset, amount), settle the USDC payment on-chain, and include the payment proof in the X-PAYMENT header to access the data. The max amount required is 20,000 base units of USDC (6 decimals), which equals $0.02. No API keys, subscriptions, or rate limits are advertised — access is purely pay-per-request.
The broader lowpaymentfee.com platform lists endpoints across categories including analytics, AI/ML (sentiment analysis, summarization, classification, embeddings), finance (price feeds, exchange rates, token quotes, gas estimates), and infrastructure utilities (geocoding, validation, conversion, generation). Documentation pages exist but appear to require a wallet connection to view, so detailed request/response schemas for this specific endpoint are not available from the crawl.
