Get Ticker Data (Single)

This endpoint allows permissioned users to retrieve ticker/index data with flexible querying options. Data can be queried by full ticker notation or individual components, allowing for broad or specific searches.

Query Parameter Semantics:

• ticker: Fully qualified ticker notation in format "{Index}.{Granularity}" (e.g., "OTMS.DAL"). When provided, automatically splits into index and granularity1 components. This is the most specific form.
• index: The base ticker/index identifier only (e.g., "OTMS"). Use this for broader queries across all granularities of an index.
• granularity1: The primary granularity dimension (e.g., "USA", "DAL"). Can be used alone or with index.
• granularity_level: Additional granularity level filtering (e.g., location codes).

Flexible Querying Examples:

• Specific ticker: ```ticker=OTMS.DAL``` → Returns OTMS index with DAL granularity
• All granularities: ```index=OTMS``` → Returns all OTMS data across all granularities
• Partial granularity: ```index=OTMS&granularity=DAL``` → Returns OTMS with XMKT granularity
• OTMS for all markets: ```index=OTMS&granularity_level=XMKT``` → Returns OTMS with XMKT granularity
• With level filter: ```index=OTMS.DAL&granularity_level=XMKT``` → Most specific query

Precedence: ticker takes precedence as it's most specific. Individual parameters override components parsed from ticker.

Required Parameters: start_date, end_date, and at least one of (ticker or index) must be provided.
