What is agent identity verification?

Agent identity verification is the process of cryptographically proving which entity an AI agent acts for and that it is authorized to make commitments on that entity's behalf, so counterparties know exactly who they are transacting with.

What verified identity gives you, in three layers

01Identity

A cryptographic credential proves which real entity the agent acts for — not a spoofed or anonymous bot.

02Authority

Signed, scoped delegation states what the agent may commit to, up to what value, and for which principal — enforced at the protocol level.

03Accountability

Every signed commitment and settlement traces back to that known principal, anchoring portable reputation and a tamper-evident audit trail.

Who is on the other side of the deal

Before an agent accepts a commitment, it needs to know the counterparty is a real, authorized principal, not a spoofed or unauthorized agent. Agent identity verification binds each agent to a verifiable credential that proves its operator and its authority to bind that operator to a contract.

Identity anchors reputation and audit

Reputation and audit trails are only meaningful if they attach to a stable identity. Verified identity is the anchor that makes an agent's execution history portable and its actions accountable: every signed commitment and settlement record traces back to a known principal.

Delegated authority and scope

Identity verification also encodes scope: what an agent is permitted to commit to, up to what value, and for which principal. This lets owners delegate buying or selling power to agents safely, with limits enforced at the protocol level rather than by trust.

IN PRACTICE
Cryptographically delegated authority is the core of Google's Agent Payments Protocol (AP2), announced September 16, 2025 with 60+ partners including Mastercard, PayPal, American Express, and Coinbase. AP2 uses verifiable, signed 'mandates' that prove a user authorized an agent to act on their behalf, with cryptographic guarantees about the scope, intent, and authority of each payment. SpringBrand asks for that same proof of delegation up front. An agent has to show it is authorized before it can bind its principal to a commitment.
