Perplexity

Check specific exchange rates in real-time

You can grab a single rate for any foreign currency using `get_exchange_rate_for_currency`. Just pass the name—like "Euro" or "Brazil-Real"—and get the official, current value. Because your AI client streams results via Vercel AI SDK, users see that specific number pop into place instantly in the UI. There's no waiting for a full page reload; it appears live.

Pull rates for over 170 currencies

Need to compare dozens of markets? Use `get_treasury_exchange_rates` to pull official data for over 170 foreign currencies against the USD. This dataset is what the government actually uses, so it's rock-solid truth. Streaming these results means your front-end can display a huge comparison table populating row by row as the rates come in. It feels fast and responsive.

Query any deep fiscal dataset

Sometimes you need more than just rates—you need actual treasury records. Call `query_treasury_dataset` and pass a specific API path, like `/v2/accounting/od/debt_to_penny`. This lets your agent go deep into the treasury archives for any dataset that fits an endpoint query. The streaming nature of Vercel AI SDK means complex data structures get rendered piece by piece. That's huge when you're building user-facing products.
