The challenge
Approved doesn't
always mean ready.
Your creative is approved. Your media is booked. Then the platform rejects the video.
A bitrate is wrong. A VAST requirement fails. A platform specification has changed. A brand element doesn't comply.
Verify catches these issues before they become delays, so you can keep your campaigns moving.
Incorrect format
VAST error
Brand element
Platform spec missed
How it works
One API between
approved and live.
A video goes in. Verify checks it against the specifications you need. You get a clear pass-or-fix verdict with actions to resolve any issues.

Validation layers
1 API
From approved to activation
The only video compliance API that validates before activation.
Verify closes the gap between approved creative and live campaigns, so every team can launch faster with fewer rejections.
Four validation layers
Verify once. Check everything.
Send a file, a link or a VAST tag. Verify runs all four layers in one call and returns a single structured verdict.
Brand
Brand safety rules and the brand elements that have to be present before a campaign goes live, applied the same way on every asset.
Editorial
Editorial standards for the destination. Mandatory disclaimers, restricted claims and category rules.
Rights
The usage rights recorded against the asset, so nothing is activated outside its approved window or territory.
Technical
VAST 4.x tags, redirects, tracking and creative packaging, plus the technical specification for the target platform.
One API. Every team. Ready for AI agents.
Your workflow stays.
Verify plugs in.
Verify isn't another dashboard. It's an API designed to sit inside the systems you already use.
