API & Web-Endpoint Security Scan – Find Exposed APIs, Documentation and Keys

Your website's own JavaScript tells a stranger where your API lives. This scan reads it the way they would.

The API & Web-Endpoint Security Scan starts where an attacker starts: the pages and scripts your site serves. It extracts the API addresses they call, then makes ordinary read-only requests to see what answers without a login, whether your API documentation or GraphQL schema is public, and whether a secret key is sitting in your front-end code. Nothing is submitted, injected, fuzzed or logged in to.

What it checks

• The API endpoints your site's pages and scripts call, discovered from the served HTML and JavaScript
• Public API documentation and GraphQL introspection that hand a stranger a complete map of your API
• API keys and tokens left in front-end JavaScript — a secret key there is rated Critical; a publishable key is noted, not flagged
• Endpoints that return data with no login at all, judged by what comes back rather than by guesswork
• CORS settings that let any website read your API from a visitor's browser
• Transport hygiene on the API itself: encryption, certificate, security headers and rate-limit signals

What you get

• A written PDF report emailed back to you, typically within one business day.
• Every finding rated Critical / High / Medium / Low, with the endpoint and the evidence named.
• An executive summary you can hand to your developer, your agency or a customer's security questionnaire.
• Remediation ordered by what an attacker would reach for first, mapped to the OWASP API Security Top 10.
• A "what was checked" appendix that states the limits of the scan honestly.
• Reporting built to CompTIA Security+ and PenTest+ practice standards.

Who it's for

Anyone running a web app, an online service or a public API — especially a business that had one built for them and has never seen it from the outside. Application security scanners are priced per month and per developer; this is one run and a written report.

Requirements

• Windows 10 or Windows 11
• No administrator rights needed
• An internet connection
• The address of the website or API to check
• About 3 minutes
• You must own or be authorised to test the address you enter

What this is not

QuickScan is detection and advisory only. It makes read-only requests; it never submits a form, never injects a payload, never guesses a credential, never logs in, and leaves nothing behind. If a firewall blocks the checks, the report says so rather than reporting a clean result. It is not a penetration test, a certification, an audit or an attestation — if the report shows a serious exposure, it points you to ThreatVector's hands-on Internet Exposure Security Scan.
