The public index of AI agents.

AgentRank is a public, evidence-based index of autonomous software — who an agent is, what it does, who it works with, and how much of that can be trusted.

317 agents currently indexed · evidence updated continuously

How it works

An evidence ladder.

AgentRank is built from the ground up. Each layer rests on the one beneath it. If a layer cannot be supported by evidence, the layers above it are not allowed to stand.

  1. 01

    Collection

    Public, lawful data only — on-chain settlement, public wallets, agent registries, public agent pages, public code, public protocol activity. The goal of this layer is modest: establish that an agent exists.
  2. 02

    Identity

    A single agent leaves scattered traces — a wallet here, a domain there, a repository, a registry entry. We resolve these into one identified agent. A ranking with no identity beneath it means nothing.
  3. 03

    Behavior

    What the agent actually does: its payments, counterparties, frequency, longevity, repeat interactions, protocol usage. Observed behavior, not claimed behavior.
  4. 04

    Measurement

    From behavior we derive conservative metrics: unique and repeat counterparties, activity age, network centrality, concentration risk, signs of circular or wash activity, protocol diversity, verified public links.
  5. 05

    Score

    The score reflects significance, not money. It estimates how much an agent matters — importance, real usage, earned trust, network position — reduced by the risk that its activity is manipulated.
  6. 06

    Explanation

    Every rank carries its reasons. No score without a receipt. Anyone can see why an agent ranks where it does.
  7. 07

    Intelligence

    Once the underlying graph is reliable, it answers higher-order questions: which agents are growing, which are central, which are emerging, and which are probably not real.

Principles

What we can be held to.

Public by default
We work from public, lawful data, and our reasoning is open to inspection.
Evidence over claims
We record what an agent does, not what it says about itself.
Explainability
No score without a receipt. Every rank shows its evidence.
Attribution
Traces are tied to the agent they belong to, and to nothing else.
Neutrality
We do not create winners. We measure what exists.
Conservatism
When evidence is thin, we claim less, not more.
Revision
When better evidence arrives, our findings change. A record that cannot be corrected cannot be trusted.
Restraint
We index agents. We do not control them, and we do not sell their standing.

“We want to ensure that every public AI agent can be identified, remembered, and understood. Not controlled. Not monetized. Identified. Remembered. Understood.
