"I am currently testing the Gemini Deep Research Agent API. I encountered the following error while running the sample code provided on the API website. Could you explain the cause?

I get the same result using the curl sample from the docs:

curl -X POST "https://generativelanguage.googleapis.com/v1alpha/interactions" \
-H "Content-Type: application/json" \
-H "x-goog-api-key: $GEMINI_API_KEY" \
-d '{
    "input": "Research the history of Google TPUs.",
    "agent": "deep-research-pro-preview-12-2025",
    "background": true
}'

{"error":{"message":"There was a problem processing your request. You will not be charged.","code":"invalid_request"}}%

Same here! If someone could get back to us on this that would be great!

I have the same problem. If someone solves it, I will be very happy.)

It looks like the api has come to life.

@Taeyoung_Kim1 I tried to reproduce this using the example Python code. It ran fine. If you keep getting the error, my best advice is to update your SDK client.

@amine-3shake I tried the latest rest example code. That also worked fine, but note it now has /v1beta/, whereas your code has /v1alpha/.
