It is hosted on lowpaymentfee.com, a platform offering a variety of pay-per-request APIs spanning finance, analytics, AI, and infrastructure — all settled on the Base L2 network using USDC.\n\nThe specific endpoint `/api/v1/finance/AXP/earnings` sits within the Finance & Web3 category of the platform. The x402 challenge confirms the endpoint is live, accepting POST requests, and charges a maximum of 20,000 base units of USDC (0x8335…on Base), which equals $0.02 per request (USDC uses 6 decimals). Payment is made via the x402 exact scheme to the specified payTo address, with a 300-second timeout window. No API keys or rate limits are advertised; access is instant once payment is included in the X-PAYMENT header.\n\nDocumentation beyond the landing page is extremely sparse — the /docs, /api, /pricing, and /README pages all render only a \"Connect wallet\" prompt with no additional technical detail. There is no OpenAPI spec, no example request/response payloads, and no description of the earnings data schema returned. The endpoint likely returns JSON (mimeType is application/json), but the exact fields, coverage period, and data source are unknown.","tags":[],"capabilities":["financial-earnings-data","stock-earnings","x402-payment","usdc-settlement","base-network","pay-per-request","no-api-key"],"categories":["finance"],"synonyms":["AXP earnings","American Express earnings","stock earnings API","financial data API","earnings report API","x402 finance","pay-per-call earnings"],"warnings":["No API documentation available — /docs, /pricing, /api, and /README pages all show only 'Connect wallet' with no content.","No OpenAPI or output schema provided; the structure of the earnings response is unknown.","Data source, update frequency, and coverage period for AXP earnings are unspecified.","No example request or response payloads available anywhere in crawled material."],"endpointUrl":"https://lowpaymentfee.com/api/v1/finance/AXP/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/AXP/earnings","description":"Premium API Access","outputSchema":{"input":{"type":"http","method":"GET","discoverable":true}},"maxAmountRequired":"20000","maxTimeoutSeconds":300}]},"qualityScore":"0.350","qualityRationale":"The endpoint is confirmed live via a valid 402 challenge with clear pricing ($0.02 USDC on Base).
