Use this API to create an agent group. Groups are lightweight named collections that reference existing agents via an agentIds array — agents themselves remain independent documents and can belong to multiple groups.

metadata is an optional, free-form object — mirroring the agent create contract. The workspace apiKey is merged into metadata.apiKey server-side. metadata is immutable after creation — there is no way to modify it via Update Group. If you need document or organization context on a group, embed it inside metadata on create.

The schema uses .strict() so unknown top-level fields are rejected with a clear validation error.

Limits:

• Workspace cap: MAX_GROUPS_PER_API_KEY = 50 (enforced via Firestore count() on create)
• Per-group cap: MAX_AGENTS_PER_GROUP = 100 (enforced inside a Firestore transaction)

Endpoint

POST https://api.velt.dev/v2/agents/groups/create

Headers

x-velt-api-key · string · required

Your API key.

x-velt-auth-token · string · required

Your Auth Token.

Body

Params

data · object · required

Show properties

name · string · required

Trimmed, non-empty. Capped at MAX_GROUP_NAME_LENGTH.

description · string

Trimmed. Capped at MAX_GROUP_DESCRIPTION_LENGTH.

agentIds · string[]

Initial members. Each id must be min 1 char. Capped at MAX_AGENTS_PER_GROUP. Built-in agent ids are accepted without a Firestore lookup; custom agent ids are validated in a single batched read. Unknown ids return NOT_FOUND.

metadata · object

Free-form metadata. Persisted verbatim; the workspace apiKey is merged in as metadata.apiKey. Immutable after creation.

Example Requests

1. Minimal group

{
  "data": {
    "name": "Brand QA"
  }
}

2. Full group with members and metadata

{
  "data": {
    "name": "Brand QA",
    "description": "All brand-quality agents",
    "agentIds": ["abc123def456", "spell-check"],
    "metadata": {
      "organizationId": "server_org_001",
      "documentId": "server_doc_001",
      "clientOrganizationId": "org_001",
      "clientDocumentId": "doc_001"
    }
  }
}

Response

Success Response

{
  "result": {
    "status": "success",
    "message": "Agent group created successfully",
    "data": {
      "group": {
        "id": "grp_9f3ac2",
        "name": "Brand QA",
        "description": "All brand-quality agents",
        "agentIds": ["abc123def456", "spell-check"],

        },
        "createdAt": 1711900000000,
        "updatedAt": 1711900000000
      }
    }
  }
}

Failure Response

{
  "error": {
    "message": "ERROR_MESSAGE",
    "status": "RESOURCE_EXHAUSTED"
  }
}

Errors:

• INVALID_ARGUMENT — Zod validation failure (missing name, unknown top-level field, etc.)
• RESOURCE_EXHAUSTED — workspace already has MAX_GROUPS_PER_API_KEY groups, OR initial agentIds exceeds MAX_AGENTS_PER_GROUP
• NOT_FOUND — one of the initial agentIds does not exist
