Get spend headroom

GET/v1/users/{userId}/budget

Reports whether the caller can spend right now: the day and month caps, what is reserved by runs in flight, what is already spent, and any operator freeze. Admission checks this same headroom before it lets a run start.

Authentication

Both headers are required.

Header: X-Api-Key: YOUR_API_KEY
Header: Authorization: Bearer YOUR_USER_TOKEN

Path parameters

userIdstring · uuidrequired

The user in the path; must equal the token's own account.
