WHAT IT DOES

What opportunity_zones_lookup_designation does on Livedatalink

`tract_vintage`	integer	—	Must be 2010. The designation boundaries and identifiers do not change with the 2020 Census.
`response_format`	string	—	Human-readable markdown or machine-readable JSON. Default markdown.

Parameters from the server's own tool schema.

RISK

Why opportunity_zones_lookup_designation is rated Low
