get_public_holidays_worldwide

Read-onlyIdempotent

FREE with any API key, including the free key by email (https://afriref.dev/free-key). Same as get_public_holidays, but for every country across all seven brands, not only Pan-African. Unmetered: never counts against the key's allowance. Pass api_key, or send the key as the X-API-Key header on /mcp.

Input Schema

Name	Required	Description
`api_key`	No	Any valid API key. Optional when the key is sent as the X-API-Key header on /mcp.
`country`	Yes	ISO country code, any covered country
`subdivision`	No	Optional ISO 3166-2 region code (e.g. 'DE-BY'). Returns national + that region's statutory holidays, each tagged national/regional. Omit for the national calendar.

Output Schema

Name	Required	Description
`unit`	No
`error`	No	Present on a free refusal or error; no charge

`bind_series`	No
`explanation`	No
`label_basis`	No	Inputs and the rule ids that produced the two labels
`subdivision`	No
`x_next_bind`	No
`http_endpoint`	No
`coverage_label`	No	How much of the question is covered: ready = complete; partial = held with a disclosed limitation or default; gap = no number served. Rules at /label-rules
`effective_from`	No
`last_confirmed`	No
`confidence_label`	No	Evidence verdict derived from source type, verification age and the stale flag (answers: the weakest series read). Rules at /label-rules
`payment_required`	No	true when the call needs payment; how_to_pay explains x402 or card
`available_subdivisions`	No

TDQS

A3.9/5.0

Behavior4/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already declare readOnly, idempotent, openWorld, and non-destructive, so the safety profile is covered. The description adds genuinely useful non-annotation context: it is free/unmetered, never counts against the key's allowance, and supports auth via either the api_key parameter or the X-API-Key header. That quota and auth detail earns credit above the annotation baseline.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Three tightly packed sentences with the value proposition front-loaded. The free-key URL and 'seven brands' phrasing lean promotional but stay short, and no sentence is wasted.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With an output schema present, return values need not be explained. The description covers scope, sibling routing, cost/quota, and auth mechanism, which is what an agent needs to invoke it. Only the optional subdivision behavior is left entirely to the schema, a minor gap.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so all three parameters (api_key, country, subdivision) are already documented in the schema, including the enum and the subdivision format. The description only restates the api_key/header auth option and adds nothing about the subdivision parameter. Baseline 3 applies when the schema carries the load.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states scope by direct analogy: 'Same as get_public_holidays, but for every country across all seven brands, not only Pan-African.' Combined with the name, an agent knows this returns public holidays globally. It stops short of a standalone verb+resource statement, relying on the sibling for the base meaning.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

It clearly establishes when to pick this over get_public_holidays (all countries vs. Pan-African only), which is the key routing decision between the two siblings. There is no explicit when-not-to-use or mention of non-holiday alternatives, but the primary selection condition is covered.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
