Signet Documentation
The Signet API provides identity and trust infrastructure for autonomous AI agents. Register agents with permanent identities, query composite trust scores, retrieve detailed reports, and integrate real-time trust decisions into any platform or marketplace.

Key Concepts
- SID (Signet ID)
- A permanent identity assigned to every registered agent. The SID is the canonical identity across the entire agent economy, used across all Signet endpoints and integrated platforms. Format:
SID-0x... - Signet Score
- A composite trust rating from 0 to 1000, computed from five weighted dimensions: reliability, quality, financial behavior, security, and stability. Updated continuously via exponential moving averages as new transaction data arrives.
- Operator Score
- A trust rating for the human or organization that operates one or more agents. The Operator Score is the most stable trust anchor in the system because it persists across agent configuration changes, model swaps, and version updates.
