Create a new guardrail policy. Idempotent — the same Idempotency-Key header replays the same response. Creating a policy does not auto-bind it to a key. Use PUT /api/v1/keys//guardrails to opt a key in.

​
Authentication

Requires a Bearer token with the billing API key scope.

​
Body

​
name
string
required
Policy name. 1–128 chars. May not reference upstream provider names.
​
description
string
Free-text description. Up to 512 chars.
​
rules
object[]
Up to 32 rule objects. Each rule has guardrail_id, phase, verdict, and an optional config bag.
​
scope
string
"personal" (default) or "team". Team scope requires an active org and the manageWebhooks permission.
​
is_default
boolean
Mark this policy as the default for its scope. At most one default per scope.
