trends___get_growth

Read-onlyIdempotent

Point-to-point growth for a keyword on one or more sources. Each window is a preset string (12M, 3M, YTD, and the other listed periods). Values are on a 0-100 scale, plus absolute volume when available. Designed for growth questions; for charting or custom math, get_time_series provides the full series. App Downloads and App Rankings are keyword sources (Android bundle ID). They are not the App Store / Google Play live boards on get_top_trends. Returns a plan-limit message when the request is rate limited or the monthly quota is used up.

Input Schema

NameRequiredDescriptionDefault
sourceYesOne source, or comma-separated sources (e.g. 'Amazon, TikTok, YouTube'). Valid: 'Google Search', 'Google Images', 'Google News', 'Google Shopping', 'YouTube', 'Wikipedia', 'TikTok', 'Amazon', 'Pinterest', 'npm', 'Python', 'Steam', 'App Downloads', 'App Rankings'.
countryNoOptional ISO 3166-1 alpha-2 code (US, GB, JP). Aliases like 'UK' or 'United Kingdom' resolve too. Only for Google Search, Google Images, Google News, Google Shopping, YouTube, TikTok, and Pinterest. Google defaults to worldwide, TikTok to US; with a country the data is fetched live.
keywordYesWhat to look up. The string format is required by source. Standard sources (Google Search, Google Images, Google News, Google Shopping, YouTube, Wikipedia, TikTok, Amazon, Pinterest): any name or phrase, e.g. 'nike'. npm: Exact npmjs.com package name, case-sensitive. Right: 'react', '@babel/core'. Wrong: 'React', 'React.js'. Python: Exact PyPI project name. Right: 'pandas', 'requests'. Wrong: 'Pandas'. Steam: Game display name in plain English, not a Steam App ID. Right: 'Elden Ring', 'CS2'. First Steam store search result wins, so use an unambiguous name. App Downloads and App Rankings: Android bundle ID only (the id= value on Google Play). Right: 'com.openai.chatgpt', 'com.whatsapp'. Wrong: 'ChatGPT', 'WhatsApp', an iOS App Store ID, or a bundle ID that is not Android. Find it at play.google.com/store/apps/details?id=THIS_PART. If the request includes App Downloads or App Rankings with other sources, keyword must still be the Android bundle ID.
languageNoOptional language edition code (en, de, ja, pt). Only for Wikipedia. Default en; other languages are fetched live.
resolutionNoOptional. 'weekly' (default, about 5 years) or 'daily' (last 90 days, fetched live). Only for Google Search, Google Images, Google News, Google Shopping, and YouTube.
percent_growthNoGrowth windows. Default if omitted: ['12M']. Each item must be a preset string: '7D', '1W', '14D', '2W', '30D', '1M', '2M', '3M', '6M', '9M', '12M', '1Y', '18M', '24M', '2Y', '36M', '3Y', '48M', '4Y', '60M', '5Y', 'MTD', 'QTD', 'YTD'. Every preset is a two-date comparison.

  5. First observed

TDQS

A4.3/5.0
Behavior4/5

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

Annotations already cover the safety profile (readOnly, idempotent, openWorld, non-destructive), and the description adds value beyond them: output values are on a 0-100 scale with absolute volume when available, and rate-limited or quota-exhausted requests return a plan-limit message rather than data. It stops short of describing response structure per window, but the scale and failure mode are disclosed.

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?

Purpose is front-loaded in the first sentence, and alternatives follow immediately. The final two sentences on app-source caveats and plan limits are somewhat dense and partially duplicate schema text, but each carries actionable information.

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 no output schema, the description carries the burden of explaining returns, and it does so at a high level (0-100 scale plus absolute volume). Rate-limit behavior is covered. What's missing is the shape of the per-window result, but the essentials for calling correctly are present.

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 coverage is 100%, so per-parameter meaning is already fully documented in the schema. The description mostly restates it ('each window is a preset string') and adds no new syntax or constraints for country, language, or resolution. Baseline 3 applies when the schema does the heavy lifting.

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?

States a specific verb and resource ('Point-to-point growth for a keyword on one or more sources') with explicit scope. It distinguishes itself from siblings by naming get_time_series for full series and get_top_trends for live app boards, so an agent can choose without opening another schema.

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

Usage Guidelines5/5

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

'Designed for growth questions; for charting or custom math, get_time_series provides the full series' gives an explicit use case and a named alternative with the condition that selects it. The clarification that App Downloads/App Rankings are keyword sources rather than the live boards on get_top_trends prevents a realistic misselection.

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