Getting Started
Installing the library
The Label Inspector is available as a Python library on PyPI. You can install it with pip
:
pip install ens-label-inspector
Starting the web server
A FastAPI application is included in the label_inspector.web_api
module. The default installation from PyPI does not include an ASGI server, so you will need to install one separately. For example, to install uvicorn:
pip install 'uvicorn[standard]'
You can start the web server with:
uvicorn label_inspector.web_api:app
Make an example request:
curl -d '{"label":"nick"}' -H "Content-Type: application/json" -X POST http://localhos
t:8000
# {"label":"nick","status":"normalized", ...
Using the AWS Lambda handler
The Label Inspector includes a handler for Amazon AWS Lambda. It is available in the label_inspector.lambda
module. You can use it to create a Lambda function that will respond to HTTP requests. It uses the mangum library.
See the included Dockerfile for an example of how to build a Lambda deployment package.
