  description: 'Point-in-time, survivorship-aware datasets for US equities and options research. Every response is JSON: {"count": N, "data": [...]} (paginated endpoints add has_more and next_cursor). Dates are always YYYY-MM-DD. Access: every dataset requires an Alphanume Pro API key (the Free plan is retired as of September 6, 2026). A 403 error with code PRO_SUBSCRIPTION_REQUIRED or DATE_RANGE_RESTRICTED means the key''s plan does not cover the request -- it does not mean the data is missing. Authentication: send your API key in the X-API-Key header (or Authorization: Bearer). Rate limit: 600 requests/minute. Keys come with a Pro subscription at https://alphanume.com/pricing. The same datasets are available as MCP tools at https://mcp.alphanume.com/mcp.'
