How to get a Google Gemini API key
The fastest key in this list — any Google account, no card, a working free tier.
What it is, and when to pick it
Google AI Studio hands out API keys with a free daily tier and no card — the fastest route from zero to a working key in this list. Pick Gemini if you already live in a Google account or want a genuinely free daily allowance. One trade-off to know: on the free tier, Google may use your prompts to improve its products, so switch to a billed key if that matters for your resume.
Step by step
Open Google AI Studio’s API-key page and sign in with any Google account. aistudio.google.com/apikey
Click “Create API key” and pick (or create) a project.
Copy the key — it starts with
AIza.
What the key looks like
AIza…Tied to the Google project you picked — revoke or rotate it any time in AI Studio.
What it actually costs
- Free tier with daily limits — no card needed.
- Free-tier prompts may be used by Google to improve products; a billed key opts you out. Switch if that matters for your resume.
- Paid tier: roughly $0.10–$2.50 per million tokens for the Flash models (estimates from Google pricing, sampled 2026-11-14).
- A typical tailored resume costs a fraction of a cent to two cents on Flash models (estimate).
Paste it into Practical Web Tools
In the AI resume tailor, choose Google Gemini in the provider list and paste the AIza… key. Calls go to Google’s native endpoint straight from your browser. Open the AI resume tailor.
If something goes wrong
- 401 — “That key was rejected”
- The key was revoked or copied incompletely — create a fresh one at aistudio.google.com/apikey and paste the full AIza… value.
- 429 — “Provider rate limit hit”
- You hit the free tier’s daily limit. It resets every day; run again after the reset, or enable billing on the project for the paid tier.
- Could not reach the provider (network / CORS)
- Google’s native endpoint echoes this site’s origin (verified 2026-11-14). A CORS error usually means an extension or proxy — try a clean browser window.
