-H "Authorization: Bearer YOUR_API_KEY"Narwhal Free includes 5,000 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.
Abstract API suits applications needing holiday coverage across 190+ countries and 3,500+ regions, with dates from 1 AD to past 2050. Paid plans support whole-year requests, while Free requires year, month and day. Enterprise adds a commercial licence, a 99.99% uptime SLA, SSO and 24/7 support. Standard is billed annually and lists 60,000 requests a year. Published update descriptions differ between weekly and monthly, so the stated schedule is inconsistent.
Yes. Narwhal Free includes 5,000 successful requests per month, commercial app use and both REST and hosted MCP access. Holiday coverage is 37 countries in 2026 and 31 in 2027, with whole-year, single-date and next-holiday lookups.
No. Abstract API requires free-plan requests to include year, month and day. Paid plans can request a whole year, so the rival example needs paid access. Narwhal supports whole-year, single-date and next-holiday lookups, with official government sources for its published countries and years.
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.
