Documentation references incorrect API endpoint (/api/v1/ vs /api/v0/)

[EclipseAditya]

The bug

The contributing documentation references incorrect API endpoints (/api/v1/) for local development verification, but the backend only serves /api/v0/. Additionally, the production nginx configuration routes to /api/v1/ while both staging and the backend use /api/v0/, creating environment inconsistency.

To Reproduce

Steps to reproduce the behavior:

1. Follow the contributing guide setup instructions in CONTRIBUTING.md or docs/contributing.md
2. Run make run to start local development environment
3. Navigate to http://localhost:8000/api/v1/ as instructed in the documentation
4. See 404 Not Found error

Expected behavior

• Documentation should reference the correct API endpoint (/api/v0/) that matches the actual backend implementation
• All environments (local, staging, production) should have consistent API routing

Additional context

Root Cause: After refactoring in commit ad007b7 (Sept 10, 2025) "Refactor API to a separate app, add v0 (#2245)"

What was updated:

• Backend: backend/settings/urls.py changed from api/v1/ to api/v0/
• Staging config: proxy/staging.conf changed from api/v1 to api/v0

What was missed:

• Production config: proxy/production.conf:30 still has api/v1
• Documentation: CONTRIBUTING.md:284, CONTRIBUTING.md:305
• Documentation: docs/contributing.md:134, docs/contributing.md:148, docs/contributing.md:150

Current State:

• Backend serves: /api/v0/
• Local: Direct access to /api/v0/
• Staging: Routes /api/v0/
• Production: Routes /api/v1/
• Documentation: References /api/v1/

Affected Files:

• CONTRIBUTING.md
• docs/contributing.md
• proxy/production.conf

Screenshots
Testing locally shows:

• http://localhost:8000/api/v0/ → Returns: {"message": "Welcome to the OWASP Nest API v0", "docs_url": "http://localhost:8000/api/v0/docs"}

• http://localhost:8000/api/v1/ → Returns: 404 Not Found
