Overview

The TechPeeker API fetches and analyses any website live at request time — no stale database. You get back every technology we detect, from JavaScript frameworks and CMS platforms to analytics tools, CDNs, and hosting providers.

The API is REST-based, returns JSON, and uses standard HTTP status codes. All requests require an API key passed via the X-API-Key header.

Real-time

Live page analysis on every request — always current, no stale index.

Any URL

Works on any domain including new sites not in major databases.

Simple auth

One API key, one header. No OAuth, no token rotation.

Authentication

Pass your API key in the X-API-Key header on every request. You can also use Authorization: Bearer <key> if your client requires it.

http

X-API-Key: sk_your_key_here

Get your key from the Dashboard → API Access page. API keys start with sk_.

Keep your API key secret. Never expose it in client-side code or public repositories.
