How do you holistically document microservices in a multi-repo setup? (programming.dev)

Let's say I had a few microservices in different repositories and they communicated over HTTP using JSON. Some services are triggered directly by other microservices, but others can be triggered by events like a timer going off, a file being dropped into a bucket, a firewall rule blocking X amount of packets and hitting a threshold, etc.

Is there a way to document the microservices together in one holistic view? Maybe, how do you visualise the data, its schema (fields, types, ...), and its flow between the microservices?

Bonus (optional) question: Is there a way to handle schema updates? For example generate code from the documentation that triggers a CI build in affected repos to ensure it still works with the updates.

For a while Peertube solely used OpenAPI to document the project. That's spec, documentation, and code generation in one. Dunno when they switched to a separate documentation tech + OpenAPI, but it's there.
