Verify every AI agent before it checks out on your site.

KnowYourAgent verifies autonomous AI agents before they transact on your merchant endpoints — and opens a pre-dispute alert the moment something looks off, so trouble lands in your dashboard instead of your chargeback queue.

What we build

Verify the agent. Enforce the trace. Keep the record.

Merchants call /api/v1/verify for identity, /api/v1/checkout/sessions for signed-trace policy, and the Pre-Dispute Network when an order is challenged.

/api/v1/verify

Six primitives. Independent contracts.

Agent Identity, Wallet Auth, Transaction Guard, Bot Classification, Merchant Verification, and the Evidence Log. Each is a stable API contract. Adopt one, or all six, without touching your processor.

Pre-Dispute Network
X-KYA-Trace-ID

Intercept the dispute before the card network sees it.

A side-channel for agent orders: the signed trace rides with every alert, and response clocks plus merchant rules give operators a window before chargeback. Identity and edge stacks do not cover this layer.

Merchants
accept / review / decline

Approve the agent order instead of sending it to review.

Verified agents complete checkout without looking like bots. When an order is challenged, the Pre-Dispute Network opens merchant-to-operator first, against the trace already on the order.

Six primitives for agent checkout.

/ AID
Agent Identity
Signed, revocable agent ID tied to a KYB-registered operator. /api/v1/verify resolves it at checkout.
/ AWA
Agent Wallet Auth
The signed trace carries principal hash, spend cap, audience, and scope. Checkout sessions fail orders outside that mandate.
/ TXG
Transaction Guard
Trust-score recommendation on verify; amount, MCC, wallet, and audience checks on the checkout session.
/ BOT
Bot Classification
Separate verified shopping agents from scrapers and credential stuffers at the checkout edge.
/ MVF
Merchant Verification
Merchant endpoints that finished onboarding get an agent-friendly signal the other side can check.
/ LOG
Evidence Log
Per-trace signed record of the verify decision and checkout session, queryable in the Pre-Dispute Network.
The problem

Most fraud systems were built for humans and retrofitted for bots. Agentic commerce needs something else entirely.

AI agents don't have credit histories. They don't match your velocity models. They look like bots to your WAF and like humans to your checkout. 3-D Secure fails them. Your chargeback policy can't locate them. Your evidence log has no row for them.

KnowYourAgent issues verifiable identity at the agent layer: cryptographic AID, a signed trace carrying the principal hash and spend scope, policy-bound transaction controls, and the Pre-Dispute Network that intercepts issues before chargebacks fire. None of it assumes a human is holding the phone.

FAQ

Common questions.

What is an AI shopping agent and why should merchants care?+

An AI shopping agent is autonomous software that browses, compares, and buys on behalf of a human customer. These agents are arriving at merchant checkouts today, and most fraud tools flag them as suspicious because they don't behave like human buyers — costing merchants legitimate revenue.

How does KnowYourAgent verify AI agents at checkout?+

Two calls at the checkout edge. The merchant calls /api/v1/verify with the agent's KYA ID and transaction context; KYA resolves the identity, the operator behind it, and the current trust level, and returns an accept / review / decline recommendation with reasons. Separately, the merchant opens /api/v1/checkout/sessions with the signed trace the operator issued upstream — that call validates the trace against a delegated wallet and enforces scope, spend cap, audience, and MCC before the card is touched.

What happens if a KYA-verified agent transaction goes wrong?+

The KYA Pre-Dispute Network runs as a side-channel between merchants and operators so problems surface before they escalate to chargebacks. If an agent exceeds its authorized scope or a customer disputes a purchase, an alert is opened against the X-KYA-Trace-ID with the signed trace, verification record, and checkout-session record attached. Merchant rules can auto-resolve matching alerts; operators can respond before escalation.

How long does it take to integrate KnowYourAgent?+

Merchant onboarding is being packaged for a guided Shopify rollout, and custom API integrations fit alongside your existing checkout logic. Merchants start with /api/v1/verify for identity and recommendation, and add /api/v1/checkout/sessions when they want signed-trace enforcement at checkout. In both cases, KYA sits alongside your existing payment and fraud stack rather than replacing it.

How much does KnowYourAgent cost?+

Merchant onboarding currently starts with a guided pilot package, with launch pricing previewed on the pricing page. Operator pricing is separate and remains available for teams registering and managing agent fleets.

Does KnowYourAgent affect the checkout experience for human customers?+

No. KYA runs as a parallel verification call alongside your existing payment processing and only activates when an AI agent is detected. Human customers see no change to the checkout flow.
