It's a split decision.
Choose YepAPI when your application needs one API for SEO, scraping, social and e-commerce data, or access to AI models, and you prefer per-call billing. Choose YouTube Data API when you are building around YouTube content, channel management, or user interactions and can work within its daily quota. These are different scopes, not interchangeable providers: YepAPI covers multiple services, while YouTube Data API exposes YouTube resources through Google’s REST API.

02Pricing at real usage
YepAPI has no subscription or monthly minimum, and its pricing lists $5 in signup credit. The listed Google SERP and web-scraping calls cost $0.01 each; keyword overview starts at $0.03 per call. The homepage lists image generation from $0.03 per image and video generation from $0.192 per second. Failed calls are not charged, and the pricing lists no rate limits. Your bill therefore grows with the calls and metered units your app uses.
YouTube Data API has no monthly fee: the default allocation is 10,000 quota units per day. A standard resource read costs 1 unit, a search query costs 100, and a video upload costs 1,600; the pricing also lists daily limits of 100 search.list calls and 100 videos.insert calls. There is no paid overage. To get more quota, developers must request it and pass a compliance audit.
03API, SDKs and integration
YepAPI uses a shared API key across endpoints and models, with JSON responses. Its documented examples use HTTP POST endpoints, including /v1/seo/keywords/overview, /v1/serp/google and /v1/scrape. The homepage links to API docs and llms.txt, and names Claude Code, Cursor, Codex, an MCP server and agent skills as integration options. It does not identify a language-specific SDK or CLI in the listed integrations.
YouTube Data API v3 is a REST service that returns JSON over HTTPS. Use an API key for public data; operations that change a user’s account require OAuth 2.0. Google’s official client libraries cover Java, Python, JavaScript, Node.js, Go, PHP, .NET, Ruby and Dart. The API’s resources cover search, videos, playlists, comments, captions and channel interactions. Calls consume endpoint-specific quota, so applications need to account for unit costs as well as authentication and the daily allocation.
04Open source, self-hosting and lock-in
YouTube Data API is a proprietary, closed-source cloud service hosted by Google, with no self-hosted or on-premises version. YepAPI does not state an open-source licence or self-hosted deployment option. Teams that need control over hosting or licence terms should confirm those points with YepAPI before committing.
Neither vendor publishes a data-export mechanism in the facts compared here. Treat migration as an integration change, not a provider switch: YepAPI covers several data services and AI models, while YouTube Data API is built around YouTube resources and its quota system. Keep the inputs and outputs your application needs in your own storage, and isolate provider-specific authentication, request schemas and quota handling behind an internal interface. That reduces the work if you later replace an endpoint or provider.
