Codex integration
Codex prepaid wallet setup
Codex workflows can grow expensive when requests loop or context gets large. Prepaid balance is useful when you want the route to stop instead of overrun. NexRelay keeps the first test small and reversible.

Why this setup works
A dedicated Codex key keeps testing separate from production while NexRelay adds prepaid balance checks and request logs.
Recommended setup
Keep the wallet topped up only as needed and use scoped keys for each client.
- One key per Codex workflow
- Start with a small budget
- Keep the model list narrow
- Review the first log entry
What to verify
Confirm the route stops at zero balance instead of continuing into overage.
FAQ
Does prepaid routing help with cost predictability?
