## Why apro-ticker-currency-support is rated Low

This tool is a simple data retrieval endpoint that queries metadata about currency support and available providers. It uses HTTP GET, accepts only filtering query parameters (strict/relaxed restriction mode), and returns informational data with no side effects. It is consistent with sibling tools like apro-ticker-currencies-list and apro-ticker-currency-price which are all read-only ticker data queries.

From the tool's own definition: "GET /v2/ticker/currency/support retrieves metadata and supported providers for one currency; no modification, deletion, or execution of external operations occurs"
