Array Vertex

Append JSON to a vertex.

An Array Vertex is an addressable JSON array. Create it once, then POST values to automatically append structured records.

Every workflow starts with a vertex.

What it does

POST means append.

Array Vertex turns a URL into a simple append-only JSON collection. Events, leads, logs, telemetry, form-derived records, and agent outputs can all land in one durable vertex.

nv create leads --type array
nv post leads '{"email":"[email protected]","company":"Analytical Engines"}'
nv get leads

Why it matters

Stop building intake APIs.

When all you need is “put this record there,” an Array Vertex gives you a secure URL, JSON storage, audit history, TTL, authentication, and workflow compatibility without custom endpoint plumbing.

POST /acme/leads
{"email":"[email protected]"}

GET /acme/leads
[{"email":"[email protected]"}]

Use cases

Simple collection. Programmable fabric.

Lead capture

Append form submissions or sales requests to a private response vertex.

Events and logs

POST operational events, agent output, or lightweight observability records.

Workflow triggers

Let Listener Vertices watch the array and trigger email, Teams, Jira, transforms, or polygons.

Vertex → Array → Listener → Polygon

A form, device, agent, payment provider, CLI, or app can append to an Array Vertex. Listener Vertex can react to new entries. Polygon Designer can turn the reaction into a workflow.

The simplest way to connect anything to anything — static, dynamic, or live.
