The release readiness scan
Security asks for an OpenAPI file before staging sign-off. The service has versioned routes added after the last published spec, so the scan completes successfully while excluding them.
For security testing workflows
Turn backend source into a security-testing baseline.
APIScout discovers the API surface from source and exports OpenAPI, so security testing can begin with the routes your application actually exposes.

The problem
Security testing is delayed when the API definition is missing or stale.
Teams often know they need API security testing but cannot supply a current specification. The result is an incomplete scope, a manual endpoint list, or a delayed test cycle.
Built for DevSecOps engineers and security engineers who need to understand the implementation before they trust the documentation.
Why this happens
The gap appears where teams are moving quickly.
The authorization review
A team wants to test object-level access controls but first needs a reliable list of entity and action endpoints to include in scope.
The manual endpoint list
Without a current spec, the handoff becomes a hand-written list. It slows the review and omits the implementation context developers need when findings come back.
How APIScout solves it
Start with the implementation, then create the handoff artifact.
APIScout runs inside VS Code and reads the backend source tree locally. It turns route discovery into an inspectable inventory, then exports OpenAPI when the API needs to move into documentation, testing, or security workflows.
- Step 01
Discover endpoints from the backend implementation.
01 - Step 02
Review the resulting API surface in VS Code.
02 - Step 03
Export OpenAPI and import it into your security testing workflow.

Benefits by role
Visibility is useful before it becomes a security requirement.
Developer benefits
Create the API definition for security testing from the project you are already working in, rather than reconstructing it manually.
Team benefits
Shorten the developer-to-security handoff and give both groups a common artifact for discussing scope.
Security benefits
Begin from a source-backed endpoint set, then use targeted runtime tests for authorization and OWASP API Top 10 risks.
In practice
Make API visibility a normal step.
Regenerate the spec when endpoints change, before requesting a test.
A successful scan of a stale spec is not complete coverage.
Review the export for expected versions and privileged operations.
Don't hand over an unreviewed route list with no version context.
Keep testing scoped to an environment with safe test identities and data.
OpenAPI cannot prove authorization behavior without runtime testing.
FAQ
Questions teams ask before they install.
Why generate OpenAPI before API security testing?
It gives the testing workflow an explicit set of paths and methods, so scope does not start from an outdated document.
Can an OpenAPI file find vulnerabilities by itself?
No. It describes the API surface. Detection requires testing requests and responses in an appropriate environment.
Where does ApyGuard fit?
It accepts the generated OpenAPI and automates API security testing across development, staging, production, and private-network environments.
When APIScout is not enough
Discovery is the beginning of the workflow.
APIScout provides discovery and the OpenAPI handoff. It does not execute attack scenarios or validate authorization at runtime — use ApyGuard or another testing process for that.
How ApyGuard extends the workflow
Test the API surface you discovered.
Import APIScout-generated OpenAPI into ApyGuard to automate testing for OWASP API Top 10 issues, authorization flaws, and vulnerabilities across development, staging, production, or private-network APIs.
