Marks the run cancelled first so no in-progress per-prompt job can flip it back to COMPLETE, then cancels every non-terminal agentic job associated with the run. The run is also archived as part of the cancel — the response returns the updated run inline (`status: CANCELLED`, `is_archived: true`); use `/unarchive` to surface it in the default `archived=false` list again. ## OpenAPI ````yaml /api/openapi.yaml post /v1/ai/eval/runs/{runId}/cancel openapi: 3.1.0 info: title: Omni API description: > The Omni REST API provides programmatic access to your Omni instance for managing users, documents, queries, schedules, and more. version: 1.0.0 contact: name: Omni Support url: https://docs.omni.co servers: - url: https://{instance}.omniapp.co/api description: Production variables: instance: default: blobsrus description: Your production Omni instance subdomain - url: https://{instance}.playground.exploreomni.dev/api description: Playground variables: instance: default: blobsrus description: Your playground Omni instance subdomain security: - bearerAuth: [] - orgApiKey: [] tags: - name: Who Am I description: Inspect your own user permissions - name: AI description: AI-powered query generation - name: AI Credit Controls description: Manage organization-level AI credit usage - name: AI Eval description: >- AI evaluation: manage prompt sets and runs used to score AI quality against curated prompt suites. - name: AI Model Suggestions description: Manage AI-generated suggestions for shared models - name: AI Routines description: >- Manage AI Routines: schedule recurring AI-powered tasks to run automatically on your data. - name: Documents v2 description: > A draft-based workflow for creating and editing documents: create a document, patch a draft, then publish.
