Run your first check

Each tool works out of the box. Here are the most common first commands:

API Contract Guardian
# Validate an OpenAPI spec against a baseline
acg validate openapi.yaml --baseline openapi-base.yaml

# Extract breaking changes between branches
acg diff main..feature/new-endpoint
Output
Validating openapi.yaml against baseline...
✓ No breaking changes detected
⚠ 2 compatible additions found:
  - POST /api/v2/users (added endpoint)
  - User.email (added property)
json2sql
# Convert a JSON file to SQL INSERT statements
json2sql users.json --dialect postgresql --output users.sql
DeployDiff
# Preview infrastructure changes
deploydiff docker-compose.yml --compare docker-compose.prod.yml
DeadCode
# Scan for unused exports in a TypeScript project
deadcode scan -p /path/to/ts-project

Add to CI/CD

Every tool returns exit code 1 on failure. Drop them into any CI pipeline.

GitHub Actions
# .github/workflows/api-contracts.yml

    runs-on: ubuntu-latest
    steps:

      - run: acg validate openapi.yaml --baseline origin/main

Free tier works in CI. All tools run locally and in CI on the free tier. Rate limits only apply to heavy batch operations. See pricing for details.
