python-sdk

Official Python SDK example

Install the standalone SDK from the workspace root:

python -m pip install ./builtwith-python
python builtwith-code-examples/python-sdk/main.py

Install from PyPI with pip install builtwith-official. Import from builtwith_official, not the unrelated builtwith package. The executable example only lists public VAT types: no key, credits, or LLM service required.

Set BUILTWITH_API_KEY in your environment to use authenticated methods. The inspect_website_technologies function is suitable for an agent tool and uses API credits when explicitly invoked. The SDK project contains async, FastAPI, LangChain/LlamaIndex, pagination and MCP examples. No existing examples change builds.
