xAI Grok Imagine video

Use the direct xAI API as a controlled media-production service: freeze the creative brief and source rights, derive a priced request, persist intent before the paid POST, reconcile its asynchronous result, then preserve the artifact and its evidence.

All volatile facts and prices below were checked against xAI first-party sources on 2026-07-10.

Choose the correct production lane

The direct endpoint is https://api.x.ai. Authenticate server-side with Authorization: Bearer $XAI_API_KEY. API keys belong to xAI Console teams and use prepaid credit or invoiced API billing.

Do not blend these separate surfaces:

• Grok on grok.com and the mobile apps uses consumer plans, weekly allowances, consumer data controls, and consumer terms. “Video 1.5 Fast” is advertised there but is not a direct-API model slug.
• Grok on X is governed by X terms and privacy rules. An X Premium or SuperGrok subscription is not API credit.
• Grok Imagine image models use /v1/images/*; voice and speech use other endpoints. Their parameters and prices do not transfer to video.
• Partner platforms and gateways—including services named in xAI marketing—may wrap xAI models but add their own schema, moderation, retention, pricing, and regions.
• Azure, Google Cloud, and other managed offerings have separate authentication, quotas, feature parity, billing, and data-governance contracts. This skill describes xAI's direct API.

The public API uses api.x.ai. xAI advertises multiple inference clusters and enterprise data-residency options, while its status page shows US and EU regional API services. Do not select a regional hostname or promise residency from a page label alone. Use only the endpoint, region, and contractual controls provisioned for the team in xAI Console or its order form/DPA.
