The frontend uses this to dynamically build the filter bar UI: - Field dropdown populated from `fields[].key` - Operator dropdown changes per field type - Value input shows autocomplete for enum fields (e.g., status) - Logical operators (AND, OR) for combining clauses ## OpenAPI ````yaml /reference-api/openapi.yaml get /traces/filter-schema openapi: 3.1.0 info: title: Agno API Reference description: The all-in-one, private, secure agent platform that runs in your cloud. version: 3.0.4 servers: [] security: [] paths: /traces/filter-schema: get: tags: - Traces - Traces summary: Get Trace Filter Schema description: >- Returns the available filterable fields, their types, valid operators, and enum values.

Two runtime shapes share this status code, and the same endpoint can return either, so ``detail`` is typed as their union: - FastAPI's request-validation handler emits a **list** of field-level errors (built-in coercion errors and custom-validator ``ValueError``s alike). - A route that raises ``HTTPException(status_code=422, detail="...")`` for a semantic check (e.g. an invalid cron expression) emits a **string** through the HTTPException handler. example: detail: - loc: - body - endpoint msg: Value error, Endpoint must be a path, not a full URL type: value_error InternalServerErrorResponse: properties: detail: type: string title: Detail description: Human-readable error message error_id: anyOf: - type: string - type: 'null' title: Error Id description: >- Stable identifier for the specific error, present only when the error carries one error_type: anyOf: - type: string - type: 'null' title: Error Type description: Category of the error, present only when the error carries one type: object required: - detail title: InternalServerErrorResponse example: detail: Internal server error FilterFieldSchema: properties: key: type: string title: Key description: Column/field name used in filter expressions label: type: string title: Label description: Human-readable display label for the UI type: type: string title: Type description: 'Field data type: string, number, datetime, enum' operators: items: type: string type: array title: Operators description: List of valid filter operators for this field values: anyOf: - items: type: string type: array - type: 'null' title: Values description: Allowed enum values (for autocomplete/dropdown) type: object required: - key - label - type - operators title: FilterFieldSchema description: Schema describing a single filterable field for the frontend filter bar.
