List every sovereign compliance pillar (regulated domain) in the Bidda registry with its live node count. Call this first to map the regulatory landscape.

Keyword search across the Bidda registry of source-verified compliance obligations. Returns matching nodes with their id, title, pillar, and a plain-language summary (BLUF). Use to find the rule that governs a topic, law, standard, or MITRE technique.

Fetch the free discovery view of a single compliance node by its id: title, pillar, version, last-updated date, plain-language summary (BLUF), dependency ids, and available crosswalk dimensions. The full 13-key vault node (deterministic workflow, actionable schema, primary citations) is available via the paid vault API.

Walk the prerequisite tree for a compliance node. Returns the prior obligations a node depends on, up to max_depth levels deep, so an agent can see the full chain of rules it must already satisfy.

Regulatory change feed: primary sources whose documents changed within the tracking window, with counts by status. Use to see what recently moved before relying on a cached rule.

Browse the registry by cross-cutting topic (e.g. 'data breach notification', 'AI transparency', 'logging & monitoring') across every pillar and jurisdiction. Returns each topic with its node, pillar, and jurisdiction counts.

Pre-flight compliance check: describe an action in natural language (e.g. 'process EU resident biometric data') and get a ranked list of regulations that may apply plus a risk indicator (LOW / MODERATE / HIGH). The headline runtime gate for autonomous agents.
