[IFTTT] I want to call and use Gemini2.0 Flash-lite from IFTTT webhooks.

I currently want to call and use Gemini2.0 Flash-lite from IFTTT webhooks.
I want you to carry out two tasks.

API Keys Set and Put the result in body of wordpress post.

■ TASK 1 : API KEY
There are two API keys for Gemini. I want to use them differently.
If Free API Key is not available, I want to use Paid API Key.

Free API Key = xxx
Paid API Key = yyyy

※I want to minimize the consumption of RPD. Because the Free quota is capped at 1500 RPD.

・What I don't want to do is make a test request for the Free API Key and if it is ok, send a production request. In that case, the RPD consumption will be doubled.

・I want to make a series of requests using the Paid API Key if the Free API Key is not available.

■ TASK 2 : Put the result in body of wordpress post.

Put the generated result into [Then→Wordpress(Create a post)] of IFTTT
