The API Surface Extractor Tool
Scan a Python or JS/TS repository and extract its API route surface — every endpoint the service exposes — so an agent can document, test, or reason about the API without reading every handler, on infrastructure you control.
Nobody knows the full API a service exposes
As a service grows, its real API surface — every route, across every file — drifts away from any spec. Without an accurate, current list of endpoints, documentation, testing, and security all suffer.
The spec lies
The documented API and the actual routes diverge over time.
Routes are scattered
Endpoints are defined across many files and patterns.
Untested surface
Endpoints nobody listed are endpoints nobody tests.
Manual extraction rots
A hand-maintained endpoint list is stale immediately.
The real route surface, extracted
Extraction
Find every route
Across the whole repo.
The tool scans a Python or JS/TS repository and extracts the API route surface — the endpoints the service actually exposes — recovering the real API as defined in code.
- Python and JS/TS support
- Whole-repository scan
- Route surface inventory
- Per-ref analysis
Extracted from code
Downstream
Feeds docs, tests, and security
A list everything depends on.
An accurate endpoint inventory is the input for API documentation, test coverage, and security review — so an agent can generate docs or flag untested routes from a trustworthy surface.
Accurate surface
Governance
On-premise analysis
Source stays internal.
Extraction runs against a snapshot inside your perimeter with audit logging, so API discovery never exposes code.
IP-safe, logged
Parameters
The api_surface_extractor tool accepts these inputs when an agent calls it. Required inputs are flagged.
Where surface extraction pays back
API documentation
Feed the real route list into generated API docs.
Coverage audits
Find endpoints with no tests.
Security review
Make sure every exposed route is accounted for.
Spec reconciliation
Compare the real surface against the documented spec.
Onboarding
Show a new engineer what the service exposes.
Agent workflows
Ground a documentation or QA agent in the real API.
Assigned to agents, orchestrated as networks
On VDF AI, an industry’s use cases map to agents, and you assign tools like this one to those agents. Compose multiple agents into a governed, on-premise network.

Questions about the API Surface Extractor tool
What does the API surface extractor do?
It scans a Python or JS/TS repository and extracts the API route surface — the endpoints the service exposes — recovering the real, current API as defined in code.
Which languages does it support?
Python and JavaScript/TypeScript, the two most common ecosystems for web services and APIs.
What do I do with the output?
The endpoint inventory feeds API documentation generation, test-coverage audits, and security review — anywhere an accurate route list matters.
Is our code exposed?
No. Extraction runs on-premise against a snapshot with audit logging.
How does it pair with other tools?
It feeds the API docs generator directly and is often assigned with the repository map and security scan.
