HTTP 429 Too Many Requests: Learn to Manage Request Limits
One thing to note is if you need a response from the external API or not. If you don't, you can use a task queue (ex. Celery) which allows you to control task execution (ie. external API calls) rates and implement backoff strategies effortlessly. This allows you to eventually make all the calls you want, so long as the timing they get made isn't important. If you do require a response from the API - you can switch to a Websocket approach, where responses will be streamed back to the client (from the gateway) once the calls are made.

Automatically reload Celery workers with a custom Django command
Celery previously had an --autoreload flag that has since been removed. However, Django has automatic reloading built into its manage.py runserver command. The absence of automatic reloading in Celery workers creates a confusing development experience: updating Python code causes the Django server to reload with the current code, but any tasks that the server fires will run stale code in the Celery worker.

Ask HN: What's the right tool for this job?
From what I've seen, there are sort of two paths. I'll provide a well known example from each.
1. lang specific distributed task library
For example, in Python, celery is a pretty popular task system. If you (the dev) are the one doing all the code and running the workflows, it might work well for you. You build the core code and functions, and it handles the processing and resource stuff with a little config.

Or lower level:

2. DAG Workflow systems
There are also whole systems for what you're describing. They've gotten especially popular in the ML ops and data engineering world. A common one is AirFlow:
