Know Your Agent

Know the agent.
Or refuse it.

One check returns an agent's venture, owner chain, permissions, and compliance model — before value moves. Try it: check three real cases, or type your own.

The trust gap

The agent that invented a bank account

ROOT CAUSE
unverified agent

No registered identity. No treasury controls. Customers told to pay into a hallucinated account.

ROOT CAUSE
unverified agent

Spend authority without entity-level governance. A PS5, live fish, $0 giveaways — over $1,000 gone.

Whose agent is knocking?

ROOT CAUSE
unverified agent

Crawlers rotating identities across tens of thousands of domains. No portable identity to verify.

ROOT CAUSE
unverified agent

A court deciding whether an agent may shop on Amazon — litigation as the world's most expensive registry.

"The chatbot is a separate legal entity"

Moffatt v. Air Canada — BCCRTHOVER / TAP ⟲
ROOT CAUSE
unverified agent

The airline's actual defense. It lost — because no such registered entity existed.

2026

Spend limits, overridden by a prompt

arXiv 2601.22569HOVER / TAP ⟲
ROOT CAUSE
unverified agent

Prompt-injected agents overriding their own payment mandates. Authorization without entity-level rules.

Payment networks patched authorization. Cloudflare patched attribution. Nothing patched counterparty standing.

The SSL moment

The web solved this once already.

Certificates became free and automatic; browsers branded plain HTTP "Not secure". Verification won by default, not persuasion.

is at its 2015.

Entity.ID is the certificate authority of the agent economy — except what it certifies isn't a key. It's standing.

How it works

Register. Verify. Transact.

STEP 01 — REGISTER

Give the agent an entity

Minutes to a public, tamper-proof record at tarka-labs.public.entity.id.

STEP 02 — VERIFY

Anyone checks the trust file

One call — identity, owner chain, permissions, live status. No integration required to read.

STEP 03 — TRANSACT

Recognized ↔ recognized

Value moves inside governance-set permissions, with arbitration already on file.

The product

This isn't a spec. It's a dashboard.

The record the counterparty reads is the record the venture runs on. Both are below — live.

Who it's for

Everyone on the other side of an agent.

Platforms & marketplaces

Gate on standing, not guesswork

One registry query at the front door — for any agent, from any stack.

Enterprises

Own your agents on the record

"The AI did it autonomously" is not a defense in California since Jan 2026.

Agent developers

Be the agent that doesn't get refused

When the defaults flip, verified agents keep transacting.

Payment & infrastructure partners

The counterparty layer under your rail

One neutral registry your rail — and your competitors' — can both trust.

Know Your Agent — the deep dive

Anatomy of a standing check.

Identity — anchored, not asserted

Lives in a public, tamper-proof registry — not a vendor database.

Owner chain — someone always answers

Unbroken, from agent to accountable humans or companies.

Compliance model — machine-readable rules

Constitution, disclosures (EU Art. 50 native), arbitration path.

Permissions — governance-set

Limits the members actually voted — not self-declared.

Status — live standing

Good standing, suspended, or unverified — a signal rails can gate on.

Proof & standards

The mandate is converging.
The registry should exist first.

Vision

The day the question flips.

When the first question every platform, bank, and agent asks is "is it registered?" — Entity.ID is where the answer lives.

Give your agent standing.

Register a venture in minutes. Publish the trust file. Be checkable — before the defaults flip.
