01 / Find your starting point

A clearer path to
API security.

From your first API inventory to a carefully scoped AI workflow. Start with the question you need to answer.

01 / FIELD GUIDE

API security, explained.

Understand inventories, identity, permissions, and the difference between an observation and a confirmed finding.

Explore API scanning
02 / FIELD GUIDE

AI without the guesswork.

Give LLMs bounded review tasks. Keep sensitive data out, human judgment in, and your evidence close.

03 / FIELD GUIDE

Your stack. Your workflow.

Plan self-hosted and CLI assessments with clear scope, controlled credentials, and a repeatable runbook.

Plan a self-hosted workflow
04 / FIELD GUIDE

Agents with boundaries.

Separate proposed actions from execution. Review tools, permissions, approvals, and stop conditions.

Understand agent guardrails
05 / FIELD GUIDE

Web apps, properly scoped.

Connect WordPress REST routes, Django permissions, and server boundaries to the actual business rule.

06 / FIELD GUIDE

Better tool decisions.

Compare free and premium workflows by evidence, operating effort, and fit—not a wall of feature claims.

Compare the tradeoffs
02 / A useful review loop

Less alert fatigue.
More understandable work.

Read the security workflow
01

Map the surface.

List routes, methods, expected callers, and owners. Keep unknowns visible.

02

Define the scope.

Agree on authorization, synthetic data, excluded operations, and stop conditions.

03

Read the evidence.

Separate tool observations, reproduced behavior, and human review decisions.

04

Repair. Then retest.

Verify the original boundary and preserve the legitimate allowed workflow.

03 / Meet your environment

From cloud APIs
to the little things
on your network.

A server, a smartphone, and a connected appliance can share a workflow—but not the same assessment boundaries.

Planning guides, not product compatibility claims. Check your selected tool’s current requirements.

04 / Put AI in the right role

A useful assistant.
Not the final authority.

Turn sanitized findings into clearer summaries, better questions, and reviewable tickets. Keep missing evidence missing—and consequential actions with the right owner.

Open the security prompt library

Editorial context only. No provider connections or partnerships.

Prompt 01 / Evidence-first triage
Review only the supplied observations.

Return:
  → What was expected
  → What was observed
  → Which evidence supports it
  → What is still unknown

Do not invent tests or declare a pass.
Human review stays in the loop

More about ApiScanner.com
What is an API scanner?

An API scanner helps inspect selected interfaces, contracts, or traffic for security-relevant observations. Its usefulness depends on scope, authentication, and the checks it actually performs. Start with the API scanner guide.

Does this website scan my API?

No. ApiScanner.com is a learning and planning resource. The report preview contains illustrative data; the site does not contact targets, collect credentials, or provide a hosted scan engine. Use the guides and checklists to plan work with an appropriate tool.

Can AI replace a security reviewer?

Use AI for bounded drafting and organization, and keep its output tied to supplied evidence. Do not treat a model-generated explanation as a verified finding. Our AI security workflow separates suggestions from decisions.

Is an API scanner the same as a firewall?

No. Assessment and traffic enforcement have different responsibilities. Neither should be treated as proof that every application permission is correct. See the scanner and firewall comparison.

Where should I start with self-hosting?

Define the approved environment, test identity, runner owner, scan mode, and report location. Then check the selected tool’s current platform requirements. The self-hosted guide helps turn those decisions into a repeatable process.

Are the guides and checklists free to read?

Yes. The guides, prompt library, scope checklist, and illustrative JSON report are available without an account. The free vs. premium guide explains how to evaluate third-party tools; it is not a pricing page for an ApiScanner.com product.

Scope first. Evidence next.

Your next step doesn’t need to be a guess.
