## FAQ

### Is this an official %{provider} integration?

RunAPI exposes a managed API surface with transparent pricing, capability, and error behavior.

### Do I need a %{provider} account?

No — your RunAPI key is enough for managed access.

### What&#39;s the latency overhead from proxying?

Typically under 20 ms. RunAPI keeps the proxy layer close to model execution regions.

### Are images / videos cached?

Generated outputs are stored and retrievable by task ID. Inputs are not cached.

### Can I bring my own key?

Not currently — calls use RunAPI-managed access.
