cala
Cala — the knowledge layer for AI agents
Cala is a knowledge graph of the world's public data: named entities, their attributes, the relationships between them, and time-stamped observations — every value carrying a source and date. Query it instead of scraping the web.
This skill assumes the Cala tools are loaded (their schemas carry the params and body shapes). It covers what the schemas can't: which tool to reach for, the query language, the read discipline, and how to fail.
Access
MCP (preferred): connect to https://api.cala.ai/mcp/ with your API key, then call the tools directly. If the Cala tools are not in your context, the server is not configured — halt and send the user to https://docs.cala.ai/integrations/mcp.
REST (fallback): base URL https://api.cala.ai/v1, header X-API-KEY: <key>. Endpoints mirror the tool names 1:1; spec at https://api.cala.ai/openapi.json. Get a key at https://console.cala.ai/api-keys.
