Tool strategy
What this tool gives you
Tune backoff and retry settings to see simulated outcomes and copy a retry handler snippet. The tool is useful before checkout because it helps buyers make one specific OpenAI-compatible API access decision without sharing private secrets.
Output
A recommendation, simulation, or guided plan that turns vague API access questions into a next action.
Next step
Use the recommendation to choose a test path, package, migration step, or 4-connection planning boundary.
