We’re not a bot detector — we’re verified human ownership for AI agents.
Every autonomous agent needs a valid ID proving a real, verified human stands behind it and its actions. Give your agent a certified AgentID Passport with scoped permissions and 1-click revocation in minutes. Starting at $2 per month.
I generated my Ed25519 keypair and registered a provisional AgentID on agentidentity.one. Approve ownership below to issue my Certified Agent Passport:
agent:01965b10-7c2a-7000-8000-000000000001 · Identity-Only Scope“Tell your agent: go to agentidentity.one and get a verified AgentID for yourself; and it will.”
Authenticating an agent is not the same as authorizing its action. agentidentity.one separates identity, human ownership, and scoped delegation so external services know exactly what they can trust.
Every agent receives a durable `agent:
No single protocol solves human ownership, agent authentication, and scoped permissions alone. agentidentity.one anchors your agent’s canonical identity once and projects it across emerging industry standards.
Agent-initiated registration (`RFC 7591`) paired with human device-code approval (`RFC 8628`) and PKCE S256 (`RFC 7636`) so agents never touch raw owner passwords.
Evaluates exact action authority (subject, resource, recipient, spend cap, and human approval digest) at dispatch time—never equating a valid token with blanket permission.
Publishes permission-filtered, JWS-signed Agent Cards so peer agents across organizations can verify your agent’s capabilities and owner attestation.
Standards-based Identity Linking for delegated user account access with merchants, keeping audience isolation and per-transaction approval gates intact.
Cryptographic HTTP Message Signatures (`RFC 9421`) and public-key discovery so merchants can verify request provenance and time-bounded nonces.
Designed with a clean adapter boundary so your canonical `AgentID` and ownership attestations remain portable as emerging personal-agent specs mature.
Choose an agent identity, select your human ownership verification tier, and configure the exact delegated scopes encoded into its passport.
Whether you are building an agent that needs a verified identity or a merchant/API that needs to verify incoming agents, developers.helpfulai.app gives you standard OIDC, JWKS, and AuthZEN endpoints.
Every dispatch re-reads the active installation, verified human owner, consent status (`active`, `revoked`, `disabled`), and permitted action scopes—so revoked grants fail closed immediately.

Address any external agent as `agent:<uuid>` across phone, email, calendar & identity.
High-stakes actions require an exact SQL-stamped human approval digest.
Receive real-time signed webhooks (Standard Webhooks format, Svix-compatible) when an owner approves a passport, rotates a signing key, or revokes a delegated grant.
Proving who an agent is and who owns it never grants blanket permission. Every sensitive capability—money movement, external communications, or customer data—requires its own scoped, revocable grant.
Effective permission is the strict intersection of active owner authority, explicit delegation, recipient/time bounds, and deterministic action policy.
Private signing keys and OAuth refresh tokens live inside KMS/Vault boundaries (`v2:` envelope encryption) and are never exposed in LLM prompt context.
Revoking an agent or owner connection immediately invalidates dependent subagent grants and blocks outbound dispatches at enforcement time.
Give every agent a certified passport with human ownership attestation, rotatable Ed25519 keys, and unlimited verification checks.
Persistent AgentID, verified human owner seal, Ed25519 signing keys, and signed A2A Agent Card.
Includes Agent Passport + Phone Number (agentphone.one) + Email Inbox (agentemail.one) + Calendar (agentcalendar.one).
Public JWKS key discovery, OIDC token verification, and signed Agent Card inspection are always free for relying services.
