On ATP

How teams use Anthropic on ATP

The same Anthropic models, with the controls a company needs around them: who can call which model, from which project, within what budget, and a record of every request.

Project API keys
Every key belongs to one project and inherits its models and balance. Revoke one at any time without touching the rest.
Model allowlist per project
Enable only the Anthropic models a project needs. Anything off the list can't be called with that project's keys.
Budgets
Credits flow from organization to workspace to project. The allocation is the cap, so one team can't spend another team's budget.
Per-request logs
Each call is recorded with its project, key, model, usage and credits debited, so spend is attributable down to a single request.
One wallet, one bill
Anthropic and the other 10 providers on ATP draw from the same prepaid credits. No separate vendor contracts or invoices.
