It is part of a broader platform offering data & analytics, AI/ML inference, finance/Web3, and infrastructure utility endpoints, all gated behind the x402 payment protocol on the Base network.\n\nThe endpoint accepts POST requests and returns JSON. Payment is settled in USDC on Base (contract 0x8335…2913) at a maximum cost of 20,000 base units, which equals $0.02 per request (USDC uses 6 decimals). There are no API keys, no rate limits, and no subscription commitments — callers simply attach an X-PAYMENT header with a valid x402 payment proof. The x402 challenge confirms the endpoint is live and version 1 of the protocol is in use, with a 300-second payment timeout.\n\nDocumentation on the site is extremely sparse: the docs, API, pricing, and README pages all render only a \"Connect wallet\" prompt with no further technical detail. No OpenAPI spec, request/response schema, or example payloads are published. Because of this, the exact request body format and the structure of the earnings response are unknown and must be discovered experimentally. The endpoint path suggests it returns earnings-related financial data for the ticker \"FDX\" (likely FedEx Corporation), but this is inferred from the URL pattern alone.","tags":[],"capabilities":["finance-data","earnings-data","x402-payment","usdc-base","micropayment","no-api-key","pay-per-request"],"categories":["finance"],"synonyms":["FDX earnings","FedEx earnings API","stock earnings data","financial data API","x402 finance endpoint","micropayment earnings","Base USDC API"],"warnings":["No API documentation available — docs, pricing, and README pages all render only 'Connect wallet' with no content","Request body schema and response schema are completely unknown","The meaning of 'FDX' in the URL path is inferred (likely FedEx ticker) but not confirmed by any documentation","No OpenAPI or machine-readable spec is published"],"endpointUrl":"https://lowpaymentfee.com/api/v1/finance/FDX/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/FDX/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 (402 challenge captured) and pricing is clear ($0.02/request in USDC on Base), but there is zero documentation on request format, response schema, or what 'FDX earnings' actually returns.
