YouTube Trends API

YouTube search-interest API

YouTube search interest trends via the YouTube Trends API. History, growth, and live YouTube trending.

Key: trendsapi.ai/#get-key. HTTP contract and every source: trendsapi-ai/trendsapi.

Authentication

pip install trendsapi-youtube

export TRENDSAPI_KEY=your_key

Python 3.9+. Same key as the HTTP API.

from trendsapi_youtube import TrendsAPI

client = TrendsAPI() # TRENDSAPI_KEY

client = TrendsAPI(api_key="YOUR_KEY")

Keyword helpers default to source: "youtube". Pass source= to hit any other platform with the same client. Official full client (every source, no preset): trendsapi.

Methods

source is lowercase (youtube). type is exact (YouTube Trending). Mixing them is a 400.

from trendsapi_youtube import TrendsAPI

client = TrendsAPI() # TRENDSAPI_KEY

client = TrendsAPI(api_key="YOUR_KEY")

series = client.get_time_series("sourdough starter") print(series[-1].date, series[-1].value)

growth = client.get_growth("sourdough starter", percent_growth=["3M", "12M"]) print(growth.results[0].growth, growth.results[0].direction)

hot = client.get_live(limit=10) print(hot.data) # [[1, "..."], ...]

get_time_series

points = client.get_time_series("sourdough starter")

Each point:

Python returns list[TrendsDataPoint]. Use .date and .value, not ["date"]. JS returns the same fields as object properties.

get_growth

g = client.get_growth("sourdough starter", percent_growth=["12M", "3M", "YTD"])

print(g.results[0].growth, g.results[0].direction)

percent_growth default: ["12M"]. Presets: 7D 14D 30D 1M 2M 3M 6M 9M 12M/1Y 18M 24M/2Y 36M/3Y 48M 60M/5Y MTD QTD YTD. Custom: {"name": "Launch", "recent": "2024-06-01", "baseline": "2024-01-01"}.

Several windows still count as one request. Python: growth.results[0].growth. JS: growth.results[0].growth.

get_live

hot = client.get_live(limit=10)

Python: hot.data. JS: hot.data. Optional offset= and category= (Amazon Best Sellers by Category, Top Websites only).

Async

import asyncio

from trendsapi_youtube import AsyncTrendsAPI

async def main(): c = AsyncTrendsAPI() return await asyncio.gather( c.get_time_series("sourdough starter"), c.get_time_series("sourdough starter", source="google search"), )

asyncio.run(main())

Each 200 is one billed request.

Pandas

from dataclasses import asdict

import pandas as pd from trendsapi_youtube import TrendsAPI

df = pd.DataFrame(asdict(p) for p in TrendsAPI().get_time_series("sourdough starter")) df["date"] = pd.to_datetime(df["date"]) print(df.set_index("date")["value"].resample("ME").mean().tail())

JavaScript / TypeScript

npm install trendsapi-youtube

Node 18+, Deno, Bun, Workers. Same API key. Field tables above apply.

Methods

import { TrendsAPI } from "trendsapi-youtube";

const client = new TrendsAPI({ apiKey: process.env.TRENDSAPI_KEY! }); const series = await client.getTimeSeries("sourdough starter"); console.log(series.at(-1)?.date, series.at(-1)?.value);

const growth = await client.getGrowth("sourdough starter", { percent_growth: ["3M", "12M"], }); console.log(growth.results[0].growth, growth.results[0].direction);

const live = await client.getLive({ limit: 10 }); console.log(live.data); // [[1, "..."], ...]

Call (curl)

curl -sS -X POST https://api.trendsapi.ai/api \

-H "Authorization: Bearer $TRENDSAPI_KEY" \ -H "Content-Type: application/json" \ -d '{"mode":"get_time_series","source":"youtube","keyword":"sourdough starter"}'

Source notes

• value is 0-100 for this term on YouTube only, not video metadata.
• type is YouTube Trending, not youtube.
• No regionCode on this endpoint.

Errors

The HTTP body field is a JSON string. SDKs decode it. Raw curl must parse body a second time.
