It is part of a broader suite of finance and Web3 APIs offered by the same provider, all priced at $0.02 per request and settled in USDC on the Base network.\n\nThe endpoint accepts POST requests and returns JSON. Payment is handled inline via the x402 protocol: callers attach an X-PAYMENT header with a signed USDC payment of up to 20,000 base units ($0.02, since USDC uses 6 decimals) on Base. There are no API keys, no rate limits, and no signup required — access is gated purely by micropayment. The payment recipient address is 0x1A2B13E97f5F837C8F9FA1F95a1484B7C70d85F3, and the maximum timeout for payment settlement is 300 seconds.\n\nDocumentation is extremely sparse. The provider's landing page lists many endpoints across data/analytics, AI/ML, finance, and infrastructure categories, but the docs, pricing, and API pages all render only a \"Connect wallet\" prompt with no further content. There is no OpenAPI schema, no request/response examples, and no description of what fields the earnings response contains or what \"NOC\" refers to. The endpoint is confirmed live (returns a valid 402 challenge), but the actual data quality and response format are unknown.","tags":[],"capabilities":["finance-data","earnings-data","x402-payment","usdc-micropayment","base-network","json-api","no-api-key"],"categories":["finance"],"synonyms":["NOC earnings","earnings API","financial data API","stock earnings","x402 finance","micropayment API","pay-per-call finance"],"warnings":["No documentation available — docs, pricing, and API pages all render only 'Connect wallet' with no content","No OpenAPI or JSON schema for request or response bodies","Unknown what 'NOC' refers to (possibly Northrop Grumman ticker, but unconfirmed)","No request or response examples available anywhere in crawled material","Data source and freshness of earnings data are completely unknown"],"endpointUrl":"https://lowpaymentfee.com/api/v1/finance/NOC/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/NOC/earnings","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.300","qualityRationale":"The endpoint is confirmed live with a valid x402 402 challenge, and pricing is clear ($0.02 USDC on Base).
