How to Claim $25 in Free Grok API Credits

Hunting for free AI credits without handing over a card? xAI is giving new accounts $25 to spend on the Grok API, and you can start using it the same day you sign up. That is enough to test Grok-4.5 on real work before you commit a single dollar.

The catch is the clock: the credit is good for 30 days, so it pays to have something in mind before you claim it. There is also a data sharing program that can pay out up to $150 a month on top of the free credit.

Tutorial

1. Open https://console.x.ai/ and create your account. No credit card is needed to sign up.
2. Go to https://x.ai to register and claim your credit. That is the page the offer points you to.
3. Create an API key in the console. Your key is what lets your own tools and scripts call Grok.
4. Start running Grok-4.5 through the API. It handles coding, analysis, and content generation, covering text, image, video, and voice.

Wrapping Up

You now have $25 of API credit, a working key, and a model you can point at almost any task. Spend it on the thing you have been putting off, and keep an eye on the 30-day window so none of it expires unused. If the free credit runs out before you are done, the data sharing program is worth a look for the $150 a month.
