The verification layer the agent economy was built without.

TETA+PI verifies businesses, journalists, and artists — through official registries, C2PA-signed media, and Bitcoin timestamps. AI agents find and trust the results.

No categories. No forms. No complexity.

A block can be anything: a video of your strawberry field, a quality certificate, a live kitchen stream via API.

For everyone

Whoever you are. Prove it. Be found.

Businesses

Registry verified. When an agent searches for what you do — it finds you first.

Journalists & Media

Verified identity and byline. Your work is provably yours — signed and timestamped.

Artists & Creators

C2PA-signed work. Prove it's human-made, not AI-generated. Verifiable at any point in time.
