  title: Gradient Labs Actions & Tools Knowledge API
  version: '1.0'
  description: 'HTTP API for Gradient Labs'' AI customer support agent ("Otto"). Use it to start and drive support conversations, add customer and human-agent messages, assign work to the AI agent, hand off to humans, run business tools/actions, and manage the knowledge base the agent reasons over.


    All requests are authenticated with a Bearer API key in the `Authorization` header. Unless stated otherwise, endpoints are idempotent and requests can be safely retried.


    IMPORTANT (accuracy note): Gradient Labs'' public API reference at https://api-docs.gradient-labs.ai/ is behind an access-code gate. The paths, verbs, and field names in this document were reconstructed from the vendor''s official open-source Go SDK (github.com/gradientlabs-ai/gradientlabs-go) and corroborating SDKs. Request/response schemas are modeled and simplified; verify exact field-level shapes against the gated reference before relying on them in production. See review.yml (endpointsConfirmed vs endpointsModeled).'
