## How to call it through Zero

```sh

```

Example prompt: Show me all the market data fields available in Gloom — I want to know what price, volume, and Bloomberg-aliased fields I can use for equities before I start building my queries.

## When to prefer this

Use this endpoint when you need to discover what market data fields are available in the Gloom platform before constructing queries — especially when mapping Bloomberg field aliases, understanding supported asset types, or building integrations that depend on field metadata. Prefer this over generic documentation lookups when you need a live, machine-readable schema catalog.

## Known failure modes

- Invalid or unrecognized 'properties' filter returns empty or error response
- Network or service downtime returns 5xx error
- Malformed query parameter returns 400 bad request
- No fields match the requested filter, returning empty data array

## How this service works
