External Data Sources

To keep results fast and focused, responses returned by our internal endpoints may be normalized and filtered before display. Typical processing includes:

• Schema mapping of raw fields into a unified model (e.g., mapping nested properties or flattening arrays).
• Applying panel-specific filters (e.g., organism, coding vs. noncoding categories, study/source filters).
• Optional transformations noted by pages, such as taking the first item from a list or mapping over an item field.
• Supplemental fetches to enrich rows with additional context (when indicated).

Developers can inspect an endpoint's exact URL, applied filters, and transformation steps with the X-ray view in data panels where available.
