Cap the v0 agent. Keep the provider key.
A v0 chat session, v0 UI generation, or v0 project build can keep calling a standing provider secret after the planned run has finished. Issue a Till key for that session with a required request ceiling so remaining capacity stays readable and the agent can stop.
Isolate the v0 traffic, not the provider account.
-
01
Issue a disposable Till key for the v0-agent job
Set the request ceiling from the planned session, retries, and tool loops, then add optional token, estimated-spend, expiry, and IP bounds when the agent needs a tighter envelope.
-
02
The provider credential stays behind Till
The v0 job uses a Till key, not an unconstrained provider secret in the workspace or agent session. When the job is retired, revoke or let expiry stop that key without rotating every connection.

03
This is not v0, a coding agent, or a secret scanner
Till does not write UI, generate apps, or replace v0. It is a hosted control layer in front of 12 AI providers: a required request ceiling and optional token, spend, expiry, and IP controls.

Pro: $59/month, 25 scoped keys, 25,000 monthly activations
Those are plan limits. Public signup is closed; request Pro beta access. Provider inference is billed by the provider. Till charges a platform subscription.
Connect provider accounts once. Each v0-agent job gets a disposable Till key with a required request ceiling and optional token, estimated-spend, expiry, and IP controls. Till is not a zero-knowledge vault, a coding agent, or a replacement for provider billing or IAM.
These are plan limits, not usage claims.
