3M Company (MMM) earnings data via x402 micropayment on Base for $0.02/request.
What it does
This endpoint provides earnings data for 3M Company (ticker: MMM) through the lowpaymentfee.com finance API. It is part of a broader platform offering data & analytics, AI/ML inference, finance/Web3, and infrastructure utility endpoints, all priced at $0.02 per request and settled via the x402 protocol using USDC on the Base network.
The endpoint accepts POST requests and returns JSON. Payment is handled inline via the x402 payment header — no API keys, accounts, or rate limits are required. The x402 challenge confirms the endpoint is live, requesting a maximum of 20,000 base units of USDC (i.e., $0.02 given USDC's 6 decimals) per call, paid to a specified address on Base.
Documentation beyond the landing page is extremely sparse — the /docs, /pricing, /api, 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 fields returned for MMM earnings data are unknown. The endpoint appears to be one of many on the platform, but the specific finance/earnings endpoints are not listed on the homepage (only /finance/prices and /finance/rates are shown), so this particular route may be less documented or newer.

Quality
The endpoint is live (402 challenge confirmed) and pricing is clear ($0.02 USDC on Base), but there is no OpenAPI spec, no request/response schema, no documentation, and no examples. The specific /finance/MMM/earnings path is not even listed on the provider's homepage, making it unclear what data is actually returned.
