## Start a top-level technique run

**post** `/runs/technique`

Starts a technique run through the normalized top-level run resource using technique_id, workspace_id, and inputs. technique_id must use the tech_ public API ID returned by list techniques. Mutating public API requests support an optional Idempotency-Key header for client retries; duplicate keys within two hours return idempotency_duplicate.

### Body Parameters

- `inputs: map[unknown]`

  Technique inputs

- `technique_id: string`

  Technique identifier. Use the public API ID returned by list techniques; it must start with tech_.

- `workspace_id: string`

  Workspace identifier. Use the public API ID returned by list workspaces; it must start with ws_.
