TETA+PI verifies businesses, journalists, and artists — through official registries, C2PA-signed media, and Bitcoin timestamps. AI agents find and trust the results.
"As autonomy increases, trust cannot be assumed — it must be proven."
Agent protocols (MCP, A2A) handle connectivity. None handle identity, verification, or provenance.
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.
Registry verified. When an agent searches for what you do — it finds you first.
Verified identity and byline. Your work is provably yours — signed and timestamped.
C2PA-signed work. Prove it's human-made, not AI-generated. Verifiable at any point in time.
Consumers always free. Verification status is never for sale. Ranking by relevance, not payment.
Connect TETA+PI MCP to any agent in one line.
Claude, GPT, custom — any MCP-compatible agent works.
