API is functional but the block-based data model is awkward for agents. Requires creating an integration and sharing pages manually. MCP server exists but inherits API limitations. Free tier limits API block reads.
Zapier

Designed for human-configured automations, not agent consumption. API is limited and focused on managing Zaps, not triggering arbitrary actions. Free tier severely restricted. MakeHQ or n8n are better for agent-driven automation.
