**FastAPI** will **extract** the data for **each field** from the **query parameters** in the request and give you the Pydantic model you defined.

## Check the Docs { #check-the-docs }

You can see the query parameters in the docs UI at `/docs`:

### Adding a Content Extractor

1. **Implement `Extractor`**:
```java
public class MyExtractor extends AbstractExtractor {
    @Override
    public ExtractData getText(InputStream in, Map<String, String> params) {
        ExtractData data = new ExtractData();
        // Extract text
        data.setContent(extractedText);
        return data;
    }
}

#!/usr/bin/env bash

echo "script failed" >resiliency-verify-healing.log # assume initial state

# Extract arguments from json object ...
FILE=$(echo $1 | jq -r '.args.file')
DIR=$(echo $1 | jq -r '.args.dir')
DEEP=$(echo $1 | jq -r '.args.deep')
WANT=$(echo $1 | jq 'del(.args)') # ... and remove args from wanted result
