The field is required, and null returns the Workspace to the platform default. A change is recorded in the audit trail with the person and the old and new thresholds; a write that changes nothing records nothing. Returns the threshold that now applies. ## Access This operation needs a Parable token. An MCP token cannot call it. See [Authentication](/getting-started/authentication.md) for the kinds of token. Your roles must grant `tenant.parables.runs.budget.threshold`. ## OpenAPI ````yaml /api-reference/openapi.json put /api/refresh-cost-threshold openapi: 3.0.3 info: description: >- Use the Workspace API to work with artifacts, connectors, Parables, and account resources. title: Workspace API version: v2026.10.22.1 servers: [] security: [] paths: /api/refresh-cost-threshold: put: tags: - Refresh cost threshold summary: Set the Workspace's Refresh cost threshold description: >- Replaces the selected Workspace’s Refresh cost threshold, in US cents: the change preview calls out a predicted cost of the next Refresh above it.
