RISK

Why apikeys_generate_api_key is rated Medium

This tool creates new API credentials, which is a Write operation that modifies account state by generating and storing authentication material. While not destructive or financial, the creation of API keys grants access privileges and could enable unauthorized data access if misused.

From the tool's definition Generate a DataNexus API key for the given email address. All users get 10 free lookups per week — registered users will be notified first when paid tiers with higher limits launch. Store the returned key — it is shown only once.
