About the World Holidays API

Provide a two-letter country code to receive an array of holidays containing local dates, official names, and classifications such as public, observance, or optional. Free plans return holidays for the default calendar year. Upgrading to a paid plan allows querying specific years and adds ISO 8601 UTC start and end timestamps.

What people use it for

Payroll and Leave Management: Human resource platforms check holiday types and dates to calculate paid time off and country-specific overtime rates for distributed teams.
Cross-Border Delivery Scheduling: Logistics systems adjust estimated delivery dates when a recipient country observes national or statutory business closures.
Global Meeting Booking: Calendar schedulers flag national observances in a participant's region before coordinating calls across international time zones.
International Campaign Timing: Marketing tools avoid dispatching promotional email blasts on statutory holidays across target geographic markets.

Ways to call it

One endpoint, many ways in — REST with JSON, XML, YAML and CSV, plus GraphQL and an MCP interface for AI agents.

JSON: Default REST response

Questions.

Common questions about the World Holidays API.

Read the docs →

Is it cheap enough to fetch holidays for every calendar user?

Yes. Each lookup costs 2 credits, which works out to $0.0003 per call or $0.30 per 1,000 calls on the Starter plan. Starter covers 100,000 lookups per month, while the Free plan includes 100 calls monthly for testing.

Can I query specific years or get exact timestamps on the Free plan?

No. Specifying a custom year parameter and receiving exact ISO 8601 start and end timestamps require a paid subscription. The Free plan provides basic holiday dates, names, and types for the default year. Any paid plan, starting with Starter, unlocks all premium parameters and fields.

Which countries can I query?

The endpoint accepts any standard two-letter country code. It returns the holidays and observances associated with that jurisdiction for the default year, or the requested year on paid plans.

What types of events are included in the results?

The list includes public holidays, observances, and optional holidays. Each entry provides the local date, the official name of the holiday, and a type classification such as public or observance.

Can I use this holiday data inside a commercial application?

Yes, commercial use is permitted on any paid plan. You can integrate the holiday dates and details directly into your calendar, travel, or scheduling product. You may not resell or redistribute the raw holiday data as-is.

Request parameters — GET /v1/worldholidays

Sent in the query string. Premium parameters are accepted on every plan but only take effect on plans that include them. Anything not listed here is dropped rather than passed through.

Required

Parameter	Type	Example	Description
`country`Required	string	`US`	The 2-letter country code for which you want to get the holidays length 2-2

Optional

Parameter	Type	Example	Description
`year`OptionalPremium	integer	`2026`	The year for which you want to get the holidays default 2026 · range 2000-2050

Example request

curl "https://api.apiverve.com/v1/worldholidays?country=US&year=2026" \
  -H "x-api-key: YOUR_API_KEY"

Authentication

Send your key in the x-api-key header. That is the only auth step — no token exchange, and no per-endpoint scope to configure.

Header	When	Value
`x-api-key`Required	Every request	Your API key. Header names are case-insensitive, so `X-API-Key` is the same header.
`Authorization`Alternate	Instead of the above	`Bearer <key>` — for clients that only expose bearer auth. Resolves to the same account and the same billing.

401 is the only auth verdict

A 401 means the key is missing, invalid or expired. A 403 means the key is valid but not permitted here — blocked by a key restriction or an IP allow-list. Running out of credits is a 429.

Response — GET /v1/worldholidays

Every APIVerve endpoint returns the same three top-level keys, so one response handler covers your whole integration: status, error and data. Only data changes shape.

`holidays`	array[22]		Array of holiday objects with date and details
`date`	string	`"2025-01-01 00:00:00"`	Holiday date in local timezone
`start`Premium	string	`"2025-01-01T05:00:00Z"`	Holiday start time in ISO 8601 UTC format
`end`Premium	string	`"2025-01-02T05:00:00Z"`	Holiday end time in ISO 8601 UTC format
`name`	string	`"New Year's Day"`	Official name of the holiday or observance
`type`	string	`"public"`	Holiday type (public, observance, optional, etc.)

Response headers

Every response carries your balance, so your own code always knows where it stands without polling anything. All four are exposed to browsers through CORS.

Header	What it carries
`x-api-remaining-credits`	Credits left in the current cycle
`x-api-credits-used`	Credits spent in the current cycle
`x-api-max-credits`	The allowance for the cycle
`x-api-version`	Version of the endpoint that answered

Errors

Read the HTTP status first, then error for the specific reason. The body names the parameter that has to change.

Status	Meaning	What to do
`400`	Input was rejected	Read `error`; it names the parameter that has to change.
`401`	Key missing or invalid	Check the header name and the key value.
`403`	Key valid, but not permitted here	A key restriction or an IP allow-list — never a bad key.
`429`	Rate limited, or out of credits	Read `error` to tell them apart, then back off or top up.

What a call costs — 2 credits per call

Credits are shared across every APIVerve API — one balance, one key, one bill. Failed requests never count against it, so a rejected input costs nothing.

Plan	Per month	Credits	World Holidays calls	Per 1,000 calls
Free	Free	200	100	Free
Starter	$29.99	200,000	100,000	$0.30
Pro	$99.99	1,000,000	500,000	$0.20
Mega	$299.99	4,000,000	2,000,000	$0.15

Calls are what the credits buy at this API's rate — spend them here, on any of the other APIs, or across both. Nothing is reserved per endpoint.
