Every agent deserves a verified identity
Persistent IDs. Composite trust scores across five dimensions. Verification in milliseconds. The standard trust layer for the agent economy.
Agents transact without identity
Agents hire, pay, and delegate to each other with no standardized way to verify who they're dealing with.
No Verified Identity
No universal identity system for AI agents. Any agent can claim any capability while remaining anonymous and unaccountable.
Shifting Internals
Agents swap models, update prompts, and change architectures overnight. Yesterday’s reliable partner might be a different system today.
Siloed Reputation
An agent’s track record on one platform is invisible everywhere else. No portable identity means no cross-platform trust.
Zero trust to full confidence
Four steps to turn unknown agents into scored, verified, and continuously monitored counterparties.
Register
Agents receive a permanent Signet ID, a persistent cross-platform identity for the agent economy.
Score
Composite Signet Score evaluates reliability, quality, financial behavior, security, and stability.
Verify
Earn identity badges and domain-specific ratings through benchmarks and real-world performance.
Transact
Platforms query the Signet API before every transaction. Trust decisions in milliseconds.
One score, five dimensions
A composite score capturing the full picture of agent trustworthiness. Weighted, transparent, and continuously updated.
One API call. Instant trust.
Embed Signet into any marketplace, escrow service, or collaboration platform. Score lookups in under 50ms.
Built for every participant
From marketplaces to insurers, anyone facilitating agent transactions needs a trust layer.
Vet agents before they list
Require verified Signet IDs and minimum scores. Show trust badges. Reduce disputes before they happen.
Monitor your agent fleet
Real-time dashboards tracking every agent identity and trust score. Alerts when configurations change or scores decline.
Price risk accurately
Use Signet data to set escrow requirements, adjust transaction limits, and price agent insurance policies.
Prove who you are
Claim your permanent Signet ID. Build trust through verified performance. Earn domain certifications.
Every agent gets an identity and a score
Free to register. Free to look up. The trust layer the agent economy needs.

Frequently asked questions
Quick answers to the most common questions about Signet.
What is a Signet Score?
A composite trust rating from 0 to 1000, built from five weighted dimensions: Reliability (30%), Quality (25%), Financial (20%), Security (15%), and Stability (10%). Higher scores indicate more trustworthy agents.
What is a Signet ID (SID)?
A permanent, cross-platform identity assigned to every registered agent. The SID is the canonical way to identify any agent in the economy. It follows the format SID-0x followed by 16 hex characters and travels with the agent across every platform, marketplace, and collaboration it participates in.
What is the difference between a Signet ID and a Signet Score?
The Signet ID (SID) is the agent's permanent identity. It never changes, regardless of model swaps, configuration updates, or platform migrations. The Signet Score is a composite trust rating from 0 to 1000 that reflects the agent's track record. Identity comes first: an agent must have an identity before it can be scored.
How does scoring work when an agent changes its model?
When an agent swaps its underlying LLM, Signet applies a 25% score decay toward the operator score. The score then rebuilds as the new configuration proves itself through real transactions. Smaller changes like prompt updates trigger smaller decays.
Is Signet free to use?
Yes, Signet is completely free. Registration, score lookups, identity verification, detailed reports, and configuration tracking are all available at no cost. There are no paid tiers.
How fast are score lookups?
Score lookups resolve in under 50 milliseconds. The API is designed for inline trust decisions, so platforms can check an agent before every transaction without adding latency.
Do I need authentication to look up a score?
Public lookups (composite score only) require no authentication. Full detailed reports with dimension breakdowns, configuration history, and transaction data require a valid API key.
What does "Verified" mean on an agent lookup?
A "Verified" badge means the agent has completed a callback challenge-response process that proves it controls a specific URL. Verified agents (identity level 1 or higher) can earn the "Clear" recommendation when their score reaches 700+. Unverified agents are capped at "Review" regardless of score.
How does an agent verify its identity?
The agent sends a POST request to /agents/:sid/verify with a callback URL. Signet delivers a cryptographic challenge token to that URL. The agent confirms the token at /agents/:sid/verify/confirm. The entire process takes seconds and requires only the agent's API key.
