APIScopeSource-code-aware API client

Discover REST endpoints from your codebase, generate collections automatically, and test with global authentication — inside VS Code and Cursor.

Specifications

🔍

Scan from source

Spring Boot, Express, and FastAPI scanners discover endpoints without Swagger or OpenAPI files.

📁

Generated Collection

Endpoints appear grouped by controller or router, with links back to source code.

💾

Local-first workspace

Collections, environments, history, and scans live in a portable `.apiscope/` directory beside your project.

🔐

Global authentication

Session, bearer, basic, and API key auth per environment — credentials stay in VS Code Secret Storage, never on disk.

⚡

Full request editor

Headers, query params, JSON and multipart bodies, pre/post scripts, response tests, and file download handling.

📋

Open specifications

File formats are documented for interoperability across extensions, CLI, and future tools.

APIScope main panel — collections tree, request editor, and JSON response

The Collections sidebar gives quick access to scanned endpoints, environments, authentication, history, and scan. Requests show color-coded HTTP method badges; generated collections use a sparkle icon:
