OTR-ID Lifecycle

​
11.1 What Is an OTR-ID

An OTR-ID is a unique identifier that the OTR system generates for every assessed domain. Format: OTR-{hash} Purpose:
  • Uniquely identify an assessed domain
  • Provide a stable reference for cross-system lookups
  • Maintain identity continuity when a domain changes

​
11.2 Lifecycle Stages

​
Creation

An OTR-ID is automatically created when a domain is first scanned by the OTR system. No manual application from the merchant is required.

​
Active

While the domain continues to be scanned periodically, its score is updated but the OTR-ID remains unchanged.

​
Domain Migration

If a merchant changes its domain (e.g., old-store.com to new-store.com), the OTR-ID can be migrated to the new domain. Historical score records for the old domain are preserved.

​
Inactive

If a domain becomes unreachable for an extended period (for example, if the domain registration expires), the OTR-ID is marked as “inactive.” It can be reactivated once the domain is restored.

​
11.3 Using an OTR-ID

​
Declaring in agent.json

{
  "trust": {
    "otr_id": "OTR-abc123def456"
  }
}

​
Referencing in API Responses

The OTR verification API response includes the OTR-ID. AI agents can use it to cache and reference a merchant’s trust information.

​
Using in Commerce Protocols

In UCP, ACP, and MCP interactions, the OTR-ID can serve as supplementary identity verification for the merchant.
