It is part of a broader Finance & Web3 API suite that includes price feeds, exchange rates, token quotes, and gas estimates. Access is gated by the x402 payment protocol: each request costs $0.02 in USDC on the Base network, with no API keys, rate limits, or subscriptions required.\n\nThe endpoint accepts POST requests and returns JSON. The x402 challenge confirms the endpoint is live, advertising a maxAmountRequired of 20,000 base units of USDC (6 decimals), which equals $0.02. Payment is settled on-chain to the specified wallet address using the USDC contract on Base (0x8335…2913). The payment timeout is 300 seconds.\n\nDocumentation 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 structure of the earnings data returned (fields, time periods, data source) is unknown and must be discovered by making a paid request. This limits the ability to evaluate data quality or completeness before purchasing.","tags":[],"capabilities":["financial-earnings-data","x402-micropayment","usdc-base-network","per-request-pricing","no-api-key","json-response"],"categories":["finance"],"synonyms":["NSC earnings","Norfolk Southern earnings API","stock earnings data","financial data API","x402 finance endpoint","micropayment earnings","Base USDC API"],"warnings":["No documentation available — /docs, /pricing, /api, and /README all show only 'Connect wallet' with no content.","No request or response schema provided; data structure must be discovered by making a paid call.","Data source and freshness of NSC earnings information is unknown.","The broader lowpaymentfee.com platform lists many diverse endpoints ($0.02 each) but provides no technical detail for any of them, raising questions about data quality."],"endpointUrl":"https://lowpaymentfee.com/api/v1/finance/NSC/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/NSC/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 402 challenge, confirming pricing and payment details.
