## How to call it through Zero

```sh
zero fetch --capability stablefinance-screener-filter-metadata-f3cd44d3
```

Example prompt: What metric fields and comparison operators are available for the StableFinance stock screener — I want to know what I can filter by before building my screen.

## When to prefer this

Use this endpoint before constructing a screener query to discover which metric names and operators are valid inputs. It acts as a schema-discovery or metadata endpoint, ideal for dynamic UI generation or agent planning steps prior to running a financial screen.

## Known failure modes

- Payment failure (402): x402 micropayment not processed correctly, endpoint returns 402
- Service unavailable (503): upstream Financial Datasets AI unreachable
- Empty metrics object: provider returns valid response but with no metrics populated (possible backend issue)

## How this service works

Filterable metric fields and operators for the screener.

## Output

A JSON object containing two keys: 'metrics' (a map of filterable metric field names to their definitions/metadata) and 'operators' (an array of string comparison operators such as 'gt', 'lt', 'eq', etc.) that can be used when constructing screener queries.
