Merck (MRK) earnings data via pay-per-call x402 endpoint on Base network using USDC.
What it does
This endpoint provides earnings data for Merck & Co. (ticker: MRK) through the x402 payment protocol. It is hosted on lowpaymentfee.com, a platform offering a variety of pay-per-request APIs spanning finance, analytics, AI/ML, and infrastructure — all settled on the Base network using USDC.
The endpoint accepts POST requests and returns JSON. Each call costs $0.02 in USDC (20,000 base units with 6 decimals), paid via the x402 payment header. The platform advertises no API keys, no rate limits, and instant access. The x402 challenge was successfully captured, confirming the endpoint is live.
Documentation is extremely sparse — the docs, pricing, API, and README pages all render only a "Connect wallet" prompt with no substantive content. There is no OpenAPI schema, no example request/response, and no description of what fields the MRK earnings response contains. The endpoint's behavior must be inferred entirely from its URL path and the platform's general listing. Users should expect a financial data payload related to Merck's earnings, but the exact schema is unknown.
