Returns everything in a rule summary plus the structured `condition` (deterministic, LLM-evaluated, or compound) and the `evidence` the pipeline used to infer it. For the complete audit trail back to source records, use [Get the provenance chain](/api-reference/get-rule-provenance). ## OpenAPI ````yaml openapi.yaml GET /v1/rules/{id} openapi: 3.1.0 info: title: Seyn API version: 1.0.0 description: > Programmatic access to Seyn for your organization. - **Ingest** data from any source with the Ingestion endpoints (requires a key with the `ingest` scope). - **Read** extracted process knowledge: search, rules, libraries, provenance, and metrics.
