A simple chat bot is needed for sending messages in Instagram Direct.

It is necessary to create a simple chat-bot or script that can send messages in Direct Instagram to a specified list of users.

Functionality:

• Authorization in Instagram (via official API or another working method).

• Mass messaging in Direct:

  • Input of the account list (username or user ID).

  • Input of the message text.

  • Ability to set a delay between sends to avoid blocks.

• Logs of sent/unsuccessful messages.

Desirable:

• Simple interface (web form or desktop application), but not critical — it can just be a script.

• Minimal hosting requirements (or running locally).

• Preferably using the official Instagram API, if possible.

Important:

• The bot must work stably and not cause instant blocks.

• Recommendations from the executor regarding safe sending limits are needed.

What I expect from you:

• Cost and deadlines for execution.

• Suggestions for technical implementation.

• Examples of similar works (if any).
