Connect an account
Use your Codex OAuth account or your OpenAI Platform API key.
YOUR MODELS, YOUR KEYS
Manage your model access in one place.
Connect an account you own, choose which models each key can use, and call them through supported API clients.
OpenAI usage is billed to your OpenAI account. Plaza does not provide payments or a wallet.
THREE STEPS
From your account to your client.
Choose model access
Enable models, then grant each Plaza key a specific subset.
Call your models
Use a Plaza key with a supported API client and review aggregate usage.
USAGE PRINCIPLES
Know what the numbers mean.
Usage is an observation and cost is an API reference estimate, not a provider invoice or payment balance. Provider permissions are confirmed when a request is made.
