tiktok_ad_library_ad_details

One TikTok Commercial Content Library ad by ID — calendar-day dates, always 2 credits. Costs 2 credits. Empty results and failures are never charged. Pass cache=true for a free 24h cache hit (default always fresh).

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
urlYesTikTok Ad Library URL or numeric ad ID. Inputs with no extractable numeric ID are a definitive 400. An ID TikTok's library positively reports as nonexistent is a definitive 404 AD_NOT_FOUND (ads outside the EU/EEA+UK+CH never enter the library, and entries expire one year after last impression). The URL platform must match this endpoint's platform. Do not pass cross-platform URLs, e.g. YouTube to TikTok, Instagram to Facebook, LinkedIn to X/Twitter, or Pinterest to Rumble.
cacheNoSet true to serve from the 24h response cache (0 credits on hit). Default false — always fetch fresh.
countryNoTwo-letter ISO country code. Default GB. Only EU/EEA + UK + CH are covered by TikTok's library; other codes return 400 UNSUPPORTED_REGION.

TDQS

A3.6/5.0
Behavior4/5

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

With no annotations provided, the description carries the full burden and does well by disclosing the fixed 2-credit cost, that empty results and failures are never charged, and that cache=true yields a free 24h hit while the default is always fresh. This is significant operational behavior beyond what a schema field alone conveys.

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?

The description is short and front-loaded, but 'always 2 credits' is repeated in the very next sentence as 'Costs 2 credits', a redundant clause that wastes space. Still, the rest is efficient and compact.

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

Completeness3/5

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

The description covers cost, caching, and failure charging, but there is no output schema and the return content is barely hinted at ('calendar-day dates' is vague). It does not explain what ad details are returned, nor does it mention the platform-matching requirement, which appears in the schema but could be highlighted. Incomplete for an agent to predict the result and prerequisites.

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 the schema already documents url, cache, and country with detailed semantics. The description mentions 'Pass cache=true' and 'default always fresh,' but this duplicates what the cache parameter's schema already states, adding no new meaning.

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

Purpose5/5

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

The description opens with 'One TikTok Commercial Content Library ad by ID', clearly identifying the resource (a single TikTok ad) and the lookup mode (by ID), which separates it from search/list routes like tiktok_ad_library_search and top_ads. Though no sibling is named, the 'by ID' scope leaves no ambiguity about what the tool does.

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

Usage Guidelines2/5

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

There is no explicit guidance on when to use this tool versus alternatives such as tiktok_ad_library_search. The 'by ID' phrasing implies the use case, and the schema mentions the URL/ad ID format, but the description itself does not state conditions like 'when you already have an ad ID' or 'use search when you need to discover ads first.'

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