TETA+PI API

FastAPI backend for TETA+PI — Trust Infrastructure for Digital Entities. Live at api.tetapi.dev, docs UI at /docs.

People, companies, brands, domains, APIs, AI models, MCP servers, and agents register as verified entities here. Verification is a set of independent, owner-triggered methods — not a single gate:

• Registry — cross-checked against official registries (Handelsregister, GLEIF, EU VAT, DE-ÖKO, …)
• Email control — 6-digit code to an address on the entity's own domain
• Domain ownership — DNS TXT record or .well-known file token
• Each method writes its own append-only verification_events row

On top of that: C2PA-signed content blocks and Bitcoin OpenTimestamps anchoring give a permanent, first-verified-at proof chain. Ranking for agent search (TWIRA = α·T + β·I + γ·P) is earned through verification history, not purchased.
