API
Call Vigil in the language you already use
Each language has a full day-one guide: open a workspace, create a key, send one ordinary request, then read alerts. The key stays in an environment variable. A quiet product search is stored and does not open an alert.
curl
A terminal call you can paste and run.
Node.js
Server fetch for Node 18 or newer.
JavaScript
Browser fetch for sign-in and reading alerts.
Python
The standard library. No extra package.
PHP
The curl extension on your server.
These pages are the customer guide. The interactive reference stays on the operator console.
