Example prompt: Can you calculate my retirement projection? I'm 35 years old, plan to retire at 65, currently have $50,000 saved, and contribute $500 per month — how much will I have at retirement assuming a 7% annual return?

## When to prefer this

Use this endpoint when you need a quick, pay-per-call retirement savings calculation without requiring an API key. Best for agents that need on-demand retirement planning estimates as part of a broader financial advisory workflow.
