Async Python client library for the Valentina Noir API

Valentina Python Client

Async and sync Python client library for accessing the Valentina Noir API.

Features

• Async and sync clients - Both VClient (async) and SyncVClient (sync) built on httpx
• Type-safe - Full type hints with Pydantic models for request/response validation
• Convenient factory pattern - Create a client once, access services from anywhere
• Automatic pagination - Stream through large datasets with iter_all() or fetch everything with list_all()
• Robust error handling - Specific exception types for different error conditions
• Idempotency support - Optional automatic idempotency keys for safe retries
• Rate limit handling - Built-in support for automatic rate limit retries

This client is a supported and up-to-date reference implementation for the Valentina Noir API.

Development Tools

Validate Constants

Verify that the Literal type constants in this package are in sync with the live API's /options endpoint. This catches drift between client and server before a release.

# Via duty task
uv run duty validate_constants

# Via script directly
uv run python scripts/validate_constants.py --api-key <key> --company-id <id>

The script reads configuration from (highest precedence first):

1. CLI arguments (--api-url, --api-key, --company-id)
2. System environment variables (VALENTINA_CLIENT_BASE_URL, VALENTINA_CLIENT_API_KEY, VALENTINA_CLIENT_DEFAULT_COMPANY_ID)
3. A .env.secret file in the project root

Exit codes: 0 = all constants match, 1 = mismatches found, 2 = missing configuration.
