Function Calling Playground

☁ Cloud AI

Define a JSON function schema and a prompt. Gemini may return a function name and arguments. DevNestro displays them and does not run the function.

Powered by Google Gemini. DevNestro is not an official Google product.

Prompt Function schema (JSON)

Name must be a short identifier. Parameters must be a JSON object. User-defined functions are never executed on this host.

This prompt and function schema will be sent to Google Gemini. DevNestro will not run the returned function.

How it works

Keep or edit the demo schema. Write a prompt that would need that function.
Confirm cloud processing. Request function sends the prompt and schema to Gemini.
Read the requested name and arguments. Nothing is invoked on DevNestro.

FAQ

Is this processed locally?

No. The prompt and schema are sent to Google Gemini. This is cloud AI, not a browser-only demo.

Does DevNestro run the function?

No. The page shows the requested function and arguments. There is no reflection, shell, or arbitrary handler.

Read the original guide: See Gemini request a function, without running it on this host.
