AI agents call Get13FHoldings to retrieve information from Fintel Discovery — Financial Intelligence for AI Agents without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.
Even though Get13FHoldings only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

Obtain cik and accession_no from SearchEdgar13F or GetEdgarCompanyFilings, then call this tool to get the actual positions. Use min_value_thousands to filter noise (e.g. 1000 = positions ≥ $1M). Use sort_by='value_desc' to see the largest positions first. Use limit (default 100) and offset for pagination — large filers can have 3,000+ positions. Check _has_more in the response to know if more pages exist. Source: SEC EDGAR Archives (13F infotable XML). No API key required..
