Signet provides an identity and trust infrastructure for autonomous agents, assigning each a permanent Signet ID and generating a composite trust score across reliability, quality, financial behavior, security, and stability. The platform offers an API that lets services verify agents and retrieve trust scores in milliseconds, enabling cross‑platform reputation and secure transactions without a centralized authority.

Problem
Autonomous AI agents operate across many platforms without a universal identity or portable reputation, making it impossible for marketplaces, escrow services, or collaboration tools to verify who they are dealing with. This lack of standardized verification leads to blind trust, increased risk of fraud, and barriers to scaling the agent economy.
Solution
Signet establishes a cross‑platform identity layer by assigning every registered agent a permanent Signet ID (SID) that serves as a persistent, cryptographically verifiable identifier. On top of this identity, Signet continuously computes a composite trust score from 0 to 1000, aggregating five weighted dimensions—reliability, quality, financial behavior, security, and stability. Platforms can query the Signet API to retrieve an agent’s score (or a full dimensional report) in under 50 ms, enabling instant trust decisions before each transaction. The scoring model is transparent, with explainable weights and decay functions that adjust scores when an agent’s configuration changes, while an operator score provides a stable trust anchor. By offering free registration, public lookups, and optional detailed reports via API key, Signet creates a neutral, infrastructure‑first trust layer that can be embedded in any AI‑agent marketplace or service.
Target Audience
Primary customers are AI‑agent marketplaces, escrow services, collaboration platforms, and other services that facilitate autonomous agent transactions, as well as developers and operators building or deploying such agents.
Features
- Permanent Signet ID (SID) that uniquely identifies an agent across all platforms and persists through configuration changes
- Composite Signet Score (0‑1000) built from five weighted dimensions: reliability (30%), quality (25%), financial behavior (20%), security (15%), stability (10%)
- Real‑time API endpoint delivering score lookups in <50 ms for inline trust decisions
- Transparent scoring algorithm with publicly visible weights, decay rules for model/prompt/tool updates, and confidence levels based on transaction volume and age
- Cryptographic callback verification to upgrade identity confidence badges
- Operator Score that anchors agent scores to the reputation of the human or organization behind the agent
- Public score lookup without authentication; detailed dimensional reports and configuration history available with an API key
