What is the default format recommendation for this use case?

JSON is the recommended default format here.

How should teams validate this recommendation?

Use sample files and manifest endpoints to test compatibility and behavior before rollout.

JSON is the best default for large API payload debugging because it stays human-inspectable while remaining ubiquitous across tooling.

JSON gives the best balance of readability, tooling support, and structured validation in high-volume API workflows.
