MCO earnings data via x402 micropayment on Base network for $0.02 per request.
What it does
This endpoint at lowpaymentfee.com provides financial earnings data for MCO (likely Multi-Corp or a specific financial entity) through the x402 payment protocol. It is part of a broader suite of Finance & Web3 APIs offered by the provider, which also includes price feeds, exchange rates, token quotes, and gas estimates.
The endpoint is live and returns a standard x402 challenge (HTTP 402) requiring payment of 20,000 base units of USDC on the Base network. Since USDC uses 6 decimals, this translates to $0.02 per request. Payment is made via the x402 "exact" scheme, settling on-chain to the specified wallet address. No API keys or rate limits are advertised — access is gated purely by micropayment.
Documentation is extremely sparse. The provider's docs, API, pricing, and README pages all render only a "Connect wallet" prompt with no additional technical detail. There is no OpenAPI schema, no request/response examples, and no description of what fields the earnings response contains or what parameters the POST body accepts. The endpoint path suggests it returns earnings-related financial data for the ticker or entity "MCO," but the exact semantics are unverified. Agents should expect a JSON response (mimeType is application/json) but will need to experiment to discover the actual schema.

Quality
The endpoint is live and returns a valid x402 challenge with clear pricing ($0.02 USDC on Base). However, there is no documentation, no OpenAPI schema, no request/response examples, and the meaning of 'MCO/earnings' is not explained anywhere. This is effectively a stub listing.
