💳Add Billing Information
You'll need to add a credit or debit card for identity verification.
⚠️Google may place a temporary $1 hold for verification — this gets refunded automatically.
⚠️You will NOT be charged when the trial ends. Google pauses your account instead of billing you. You'd have to manually upgrade to continue.

✅Verify Your Identity
Google may ask you to complete a few quick verification steps:

✓Confirm your country
✓Accept terms & conditions

🔑Get Your API Key & Link BillingImportant
Go to Google AI Studio to create your API key. This is the critical step most people miss.
⚠️ You MUST link a billing account
Even with $300 free credit, your API key defaults to the free tier unless you link a billing account. Go to AI Studio → click your API key → "Set up billing" or visit the billing page. This upgrades you from Free tier to Tier 1 (paid) — your $300 credit covers all charges, so you pay nothing.

🚀Add the Key to KDP Robots

How Far Does $300 Go?KDP Robots primarily uses Gemini 2.5 Flash ($0.30/M input + $2.50/M output tokens). Here's a rough estimate based on typical usage. Pricing sourced from official Gemini pricing:
