Obsidian developer documentation

Obsidian turns the world's official regulatory sources into verified, tier‑0, machine‑readable intelligence. Bring it into the AI assistant you already use through the MCP server, or into your own systems through the enterprise API.

Two ways to integrate

Both surfaces read from the same verified regulatory database. Pick the one that matches how you want to consume it.

• MCP (Model Context Protocol) — the fastest path. Connect Obsidian to any MCP‑capable assistant and it gains a regulatory_search tool that returns sourced, citation‑backed answers. Start at MCP overview.
• Enterprise API — for programmatic access. A REST API authenticated with an API key, for feeds, internal tools and data pipelines. Start at API overview.

What makes it different

Everything Obsidian returns is built to be cited, not guessed.

• Straight from the regulator. Indexed from primary sources, government agencies and regulatory bodies — the official text, not a model's recollection of it.
• Every result is cited. Each item carries its official reference and a link back to source.
• Status & jurisdiction aware. Results state whether a rule is in force, proposed or repealed, and the jurisdiction it applies to.
• Scoped to you. Results are automatically limited to the industries your account covers (ESG, chemicals, life sciences & medtech).

Access & plans

A free Obsidian account unlocks both surfaces. Usage is metered in verified requests per month (one tool call or one API request = one verified request).
