AgentID gives an AI agent something it normally has to borrow: an identity of its own. One API provides an email inbox, a phone number, a credential vault and a payment card, so an agent can create accounts and clear verification steps on the ordinary web rather than stopping at the first form that asks who it is.

The problem it removes is a familiar one. An agent with no inbox and no number cannot receive a confirmation code, so the usual workaround is to paste your own credentials into the conversation — at which point they live in the agent’s context and in the transcript, and you have handed a long-lived secret to something you cannot fully audit.

Instead the agent is issued its own identity and calls endpoints for each step: mint an identity, resolve a secret into a form without the value passing through its context, collect the verification code that was sent to its own inbox or number, and pay with a single-use card. Every release of a secret is recorded, so there is an audit trail of exactly what the agent was given and when.

Underneath it is built on the infrastructure each job actually needs — Resend with DKIM for deliverable mail, Twilio for numbers, Stripe Issuing for cards, browser-use and CDP on the browser side — with a FastAPI and Postgres core, AES-GCM at rest, and webhooks for anything downstream.
