Questions about using Narwhal

Can I use the data in a commercial product?

Yes, on every plan. Credit the source shown with each series. Reselling Narwhal itself as a data feed needs an Enterprise licence.

Read the terms
Where does the data come from, and how often does it update?

Sources and schedules depend on the dataset. Our methodology explains how each series is collected and interpreted, while the freshness documentation explains the dates and update cadence.

Read the methodology
How much historical data is available?

Free includes the last 12 months, Basic the last 5 years, and Pro the full history. Coverage also varies by country, indicator, and product; check the coverage pages and endpoint documentation for the series you want to use.

Check coverage
What happens when I reach my plan’s limit?

Requests can be rejected when you reach your monthly allowance or a request-rate limit. There are no automatic overage charges. Your dashboard shows your plan, usage, and available options.
