Know your APIs. Own your next step.

A practical home for API security learning

ApiScanner.com is an independent learning and planning resource for people building, operating, and reviewing APIs. It brings API scanning fundamentals, self-hosted workflows, AI-assisted review, application security, and device boundaries into one readable collection.

The goal is straightforward: help you ask a better assessment question, recognize the limits of the evidence, and identify a useful next action. A long report is not the same as an understood risk. A small, well-documented test can be more useful than a dashboard full of unexplained results.

Who these resources are for

Developers can start with route ownership and permission behavior. Operators can use the self-hosted and cloud guides to plan runners, credentials, and evidence handling. Security reviewers can use the scope checklist and illustrative report to structure a handoff. Teams exploring AI can begin with narrow prompts rather than unrestricted agent execution.

The examples use synthetic environments so the discussion can focus on the control and the decision. They are not case studies of named customers, claims of product performance, or measurements of real systems.

What you will find here

The API Security Field Notes cover ten distinct long-form topics. The resource library provides a scope checklist, six AI prompts, an evaluation worksheet, and an illustrative report. Topic guides connect those resources to platforms and workflows.

All of this content is available without an account. The site does not operate a hosted scanner, sell scanner subscriptions, accept credentials, or connect to your infrastructure. Third-party tools and model names appear for context, not as partnership or integration claims.

How to read the guidance

Treat recommendations as planning steps to adapt to your authorized environment. Verify software behavior against the documentation for the version you operate. Keep untested questions visible and bring consequential judgments to the people responsible for the application.

Read the editorial approach for the distinction between evidence, examples, and recommendations. For an error, clarification, or topic suggestion, use the contact page. Please send only the minimum sanitized information needed to explain the issue.
