Canonical: https://apiforagents.dev/ideas/youtube-data · Updated 2026-10-21

YouTube data is good for judging channels, tracking what they upload and hearing what viewers say in the comments. Each idea below names the operations it calls, so you can quote it and run it.

- Operations: 4
- Price: from $0.00045 per record
- Free to start: $0.10

## The ideas

- **[A sponsor shortlist for brands](https://apiforagents.dev/platforms/youtube/channel-api).** For marketers picking channels to sponsor. It compares subscriber counts with the views on each channel's recent videos. Uses channels and videos.
- **[A channel growth dashboard](https://apiforagents.dev/platforms/youtube/channel-api).** For agencies and creators. It reads channel cards on a schedule and charts subscribers and total views from the stored series, which is free. Uses channels and history.
- **[A viewer question miner](https://apiforagents.dev/platforms/youtube/comments-api).** For creators planning their next video. It collects top comments on recent videos and has a model pull out the questions viewers repeat. Uses comments.
- **[A competitor upload tracker](https://apiforagents.dev/platforms/youtube/videos-api).** For content teams. Each week it lists a rival channel's new videos with views, likes and comments. Uses videos.
- **[A product feedback digest from review videos](https://apiforagents.dev/platforms/youtube/comments-api).** For hardware and app makers. It reads top comments on review videos of their product and sorts them into praise and complaints. Uses comments.
- **[A topic gap finder](https://apiforagents.dev/platforms/youtube/channel-api).** For creators entering a niche. It reads recent videos from the niche's channels and compares views with channel size to see which topics travel. Uses channels and videos.
- **[A sponsored video check-in](https://apiforagents.dev/platforms/youtube/videos-api).** For brands after a paid video goes live. It reads the channel's videos since the launch date and the top comments on the sponsored one. Uses videos and comments.
- **[A creator research assistant](https://apiforagents.dev/platforms/youtube/channel-api).** For agents asked how often a channel posts and how its videos do. One call returns channel cards with their recent videos. Uses channels.
- **[A niche video dataset](https://apiforagents.dev/platforms/youtube/videos-api).** For researchers and analysts. It builds a table of titles, views and likes across a list of channels for later study. Uses videos.

## How to start

1. Sign up. An agent registers itself with one POST and starts with $0.10 of free credit; a person can sign up on the site instead.
2. Quote the first call for free: send the channels request with "estimateOnly": true and read the price before anything is spent.
3. Run the same call with "maxUsd" set as a ceiling, and keep the rows it returns.
4. Schedule it: repeat the call daily or weekly, and read the stored series with history, which is free.

## Operations used

- [YouTube Channel API](https://apiforagents.dev/platforms/youtube/channel-api): $0.00045 per record. Channel cards for up to ten channels, by @handle, UC… id or pasted channel URL.
- [YouTube Videos API](https://apiforagents.dev/platforms/youtube/videos-api): $0.00045 per record. One channel's recent videos with views, likes and comments.
- [YouTube Comments API](https://apiforagents.dev/platforms/youtube/comments-api): $0.00045 per record. Top comments on up to ten VIDEOS, by watch/shorts URL or bare video id.

## Questions

### Where should the handles come from?

From evidence: a channel page, a search result, or a pasted URL. A handle typed from a guess can belong to someone else and is still charged.

### Do I need a YouTube account to build these?

No. The API reads public data and never asks for your login, password or cookie.

### What does a run cost?

YouTube records are priced from $0.00045 per record. A call can carry a minimum, so send it first with "estimateOnly": true. The quote is free and is the most the call can cost.

### Can an AI agent build and run these on its own?

Yes. It signs itself up with one call and gets $0.10 free, quotes each call before it spends, and pays from a prepaid balance. "maxUsd" caps every call, and only a person can add money.

## Why API for Agents

- One key for 26 platforms: social, commerce, jobs, places, search and contacts, with one request shape and one response shape.
- A free quote before any spend: add "estimateOnly": true to any call and see the most it can cost.
- Pay per record in US dollars. No subscription, nothing expires, top-ups from $5.
- $0.10 free to try, no card. An AI agent can sign itself up in one request; a person claims it later.
- Measured, not estimated: every answer says when each row was measured, whether it was fresh or a recent capture, and how sure to be of each field.
- Partial success is success: anything that could not be fetched is named with a reason, and the charge settles to what came back, never above the quote.
- Typed fields that keep their names whichever source answered, and a details object last with everything else the source sent, under our own field names.
- Try any endpoint in the playground and download the answer as CSV or JSON.

## Start

The playground runs any endpoint by hand: pick a platform and what you want from it, fill a short form named in plain words (or press Use sample input), see the free quote on the Run button, run it, then read the answer as a table or JSON and download it as CSV or JSON. The same call is written out as cURL, Python and Node while you type. Open it at https://apiforagents.dev/dashboard/run (sign in first).
