Grok API

Name: Grok API
Brand: SpaceXAI (formerly xAI)

by SpaceXAI (formerly xAI)

#5 in Model APIs & token credits

I'd use it if you want Grok in your app. Grok 4.7 takes 500K-token prompts, and live web and X search come built in.

What’s good

Grok 4.7: $2 per 1M input tokens
Live web and X search built in
Image, video and voice APIs too

Heads-up

Prompts over 200K tokens cost double

The details

Best for: Builders who want Grok models with live web and X search
Price: Pay as you go (Pay per token from prepaid credits)
Free plan: No
Skill level: Built for pros
Made by: SpaceXAI (formerly xAI)
