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.\n\nThe 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.\n\nDocumentation 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.","tags":[],"capabilities":["x402-payment","finance-data","earnings-data","usdc-micropayment","base-network","json-response","no-api-key","pay-per-request"],"categories":["finance"],"synonyms":["MCO earnings","financial earnings API","earnings data endpoint","x402 finance API","micropayment earnings","crypto pay-per-call finance","lowpaymentfee earnings"],"warnings":["No documentation available — docs, API, pricing, and README pages all show only 'Connect wallet' with no content.","No OpenAPI or request/response schema provided; request body and response format are unknown.","The meaning of 'MCO' in the endpoint path is not documented; it could refer to various financial entities or tickers.","No SLA, rate limit, or uptime guarantees documented."],"endpointUrl":"https://lowpaymentfee.com/api/v1/finance/MCO/earnings","protocol":"x402","transport":"http","auth":{"type":"x402","details":[{"asset":"0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913","extra":{"name":"USD Coin","version":"2"},"payTo":"0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3","scheme":"exact","network":"base","mimeType":"application/json","resource":"https://lowpaymentfee.com/api/v1/finance/MCO/earnings","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.300","qualityRationale":"The endpoint is live and returns a valid x402 challenge with clear pricing ($0.02 USDC on Base).
