# Quickstart

# Quickstart

Get from zero to an explainable decision when API access is provisioned. Path: **sandbox first**, then the same integration shapes in **production when Vence enables live** for your program.

>

Intended hosts `sandbox.api.vence.one` and `api.vence.one` are **founder-beta / coming online**. Use the base URL Vence gives your org (Console or Contact us). Do not assume public live DNS today.

### Open Console (sandbox)

Sign in at [console.vence.one](https://console.vence.one) with an invite and create a **sandbox** API key.

### Create an entity

`POST /v1/entities` with your bearer key against your provisioned sandbox base URL (intended hostname: `https://sandbox.api.vence.one`).

### Attach signals

Link identity and ingest transactions or feature snapshots as your program requires.

### Underwrite

Call the underwrite endpoint. Read verdict, reasons, and versions.

### Fulfill on webhooks

Verify signatures and act on decision events.

### Graduate to production when enabled

Point the same SDK at your live base URL (intended hostname: `https://api.vence.one`) with a live key when Vence enables production. [Contact us](https://vence.one/contact) for commercial access.
