n8n-nodes-treg

An n8n community node for Treg, the agent-tool catalog and credential proxy.

Included operations

• Search Catalog
• Get Endpoint
• Call Endpoint or a team-owned tool
• Get Call Result
• Get Balance
• List Calls

Paid calls use a required per-call cost ceiling. The output includes the response body under data
and billing/audit information under _treg, including the actual cost and X-Treg-Call-Id.

Credentials

Create a Treg API credential in n8n with:

• API Token: a Treg token for the intended team
• Base URL: https://treg.to unless using a self-hosted registry
• Organization Slug: only needed when an identity token belongs to several teams

For unattended workflows, an org-scoped agent token is preferable to a human identity token.

Local installation

Do not install while a crucial n8n execution is running. When a restart is safe:

cd ~/.n8n/nodes
npm install /absolute/path/to/n8n-nodes-treg-0.1.0.tgz

Restart n8n after installation so it discovers the new credential and node.

Call safety

• Maximum Cost (USD) is sent as X-Treg-Route-Max-Cost on every call.
• Idempotency Key can safely retry the same request without paying twice.
• _treg.costMicro is the settled cost; catalog prices are estimates.
• _treg.callId should be kept for audit and result recovery.
• List Calls is operational history, not an invoice source.
