## Questions

### How much does the Aura-2 API cost?

Deepgram's published list rate for Aura-2 is $30 per 1M characters (checked 2026-10-05). The provider account you connect bills you at the rate on that account, so a negotiated rate replaces the list rate. INFRO adds 0% to model spend.

### Which providers serve Aura-2?

In INFRO's provider registry, Aura-2 can be served by OpenRouter. You connect your own account with any of them, and INFRO routes and fails over between the ones you connect.

### What is the Aura-2 model ID?

Request it from INFRO as "deepgram/aura-2". INFRO sends each provider its own id: OpenRouter "deepgram/aura-2".

### How do I call Aura-2 through an OpenAI-compatible API?

Point an OpenAI SDK, or any HTTP client, at https://api.infro.io/v1 with an INFRO gateway key and send model "deepgram/aura-2" to POST /v1/audio/speech. INFRO runs the request on a provider account you connected and returns the provider's response with an estimated cost.

### Does INFRO mark up Aura-2 usage?

No. Deepgram or the provider you connect bills model usage to your own account. INFRO charges a software subscription for routing, failover, observability, budgets and policy, and takes 0% of model spend.
