-H "Authorization: Bearer YOUR_API_KEY"Narwhal Free includes 3,000 successful requests each month and permits commercial apps. Use that allowance for a dashboard, scheduled data fetches or an agent integration. Move to Basic for 100,000 monthly requests as usage grows, with the same account and authentication.
REST and hosted MCP reach the same data through one account. Your application can fetch JSON while an agent uses the hosted tools, with every successful call counted once against the shared allowance. One quota makes the combined workload straightforward to budget.
Narwhal publishes holidays for 37 countries. Fetch a whole year, look up a date or find the next holiday through three documented operations. Add economic release dates and FX to the same workflow, using one account for both your scheduling logic and country data.
Calendarific is the better pick for holiday coverage across more than 230 countries and 3,300 regions. Its catalogue includes national holidays, local observances and religious holidays, with filters for narrowing the results. Starter removes attribution and includes complete historical and upcoming data. Enterprise adds daily updates. That range suits products built primarily around regional holiday information, particularly when coverage breadth is the deciding factor.
Yes. Narwhal Free includes 3,000 successful requests per month, commercial app use and both REST and hosted MCP access. Use public holidays alongside economic release schedules and FX in one application.
Calendarific lists quarterly dataset updates on Free and Starter, weekly updates on Business and daily updates on Enterprise. Starter removes the attribution requirement and includes 10,000 monthly calls. It costs $12 with monthly billing or $100 paid annually; Enterprise is billed annually and includes 50 million monthly calls.
Replace the request URL and authentication, then map the JSON response into your application's fields. The examples use standard fetch in JavaScript and requests in Python, so integration fits an ordinary HTTP client. Keep your key on the server and carry the response's units, dates and missing values into your display or calculations.
The shared cap applies to successful REST and MCP requests together. There are no automatic overage charges. Basic includes 100,000 monthly requests; quotas reset each month even when you pay yearly.
