Why developers search for this
Most AI API searches come from a practical problem: connect a tool, keep a key safe, avoid surprise cost, or understand which request consumed credits.
Controls that matter
A useful gateway should make the first test small, visible, and reversible.
- Prepaid balance protection
- Dedicated API keys per tool or app
- Daily and monthly budgets
- Model allowlists and max output caps
- Request logs with token meters and billed amount
How to test safely
Create an account, verify email, use trial credits, create one scoped key, send one small request, and inspect the ledger before recharging or increasing limits.
FAQ
What is the first step for token cost estimation?
Start with a dedicated test key and a small budget, then confirm the first request in usage logs.
Does this require changing every client?
Usually no. Compatible clients can often keep the same request format while using a different base URL and API key.
