Hello,

Yes, the current version of LangChain does support form data submission in the Open API Chain. This is evident from the presence of POST and PATCH methods in the code. Both methods require a "data" key in the input, which should be a dictionary of key-value pairs. This is typically how form data is submitted in HTTP requests.

However, regarding your specific question about sending a binary file as form data, I wasn't able to find a definitive answer within the repository. The "data" key in the POST and PATCH methods might support binary data submission, but the required format for submitting binary data in the "data" key is not explicitly mentioned in the repository.

I recommend trying to submit the binary file as a base64 encoded string in the "data" dictionary, as this is a common practice for sending binary data in HTTP requests. Here's an example of how you might do this:

import base64

# Read binary file
with open('yourfile.bin', 'rb') as f:
    binary_file_data = f.read()

# Encode binary data to base64
base64_encoded_data = base64.b64encode(binary_file_data)

# Convert to string
base64_message = base64_encoded_data.decode('utf-8')

# Now you can send base64_message in the "data" dictionary

Please try this and let me know if it works for you. If it doesn't, could you please provide more details about the binary file and the API you're trying to interact with? This will help me to give you a more accurate answer.

Best regards,
Dosu
