Whisper API: questions

How much does the Whisper API cost on varg?
The lowest price the catalog states in the Whisper family is from $0.03 per run, on Groq Whisper Turbo and Groq Whisper. Every model is billed at its provider's price with no markup, from one credit balance: 1 credit is $0.01. For the exact price of a request before you run it, send the same body to POST https://api.varg.ai/v2/estimate.
Which Whisper models are on varg?
5: Groq Whisper Turbo (from $0.03 per run), Groq Whisper (from $0.03 per run), Groq Whisper Large v3 (from $0.06 per run), Whisper (from $0.05 per run) and Whisper Large v3 (from $0.05 per run). Each has its own page with the parameters and a call to copy.
How long do Whisper requests take?
Typically from about 5 s (Groq Whisper Turbo) to about 30 s (Whisper), by the catalog's estimates for each model's fastest route. The API answers at once with a job id, so nothing waits on an open connection while it runs.
How do I call the Whisper API?
Send POST https://api.varg.ai/v2/tools/transcription/call with the header "Authorization: Bearer $VARG_API_KEY" and a JSON body that includes "model", for example "model": "groq_whisper_large_v3_turbo". The call answers 202 with a job right away. Poll GET https://api.varg.ai/v2/jobs/{id} until "status" is "completed", then read output.outputs[0].url, or pass options.webhook_url to be called back.
Can I use Whisper from Claude, ChatGPT or Cursor?
Yes. Add the varg MCP server (https://mcp.varg.ai/mcp) to Claude, ChatGPT, Cursor or any other MCP client and sign in with varg, with no API key to paste. The agent runs a model with call_tool, passing tool "transcription" and the model id, for example "model": "groq_whisper_large_v3_turbo".
