Questions about our developer API, pricing, and free browser tools.

Developer docsBrowse free tools

  • What is the ToolYour Tools API?

    The ToolYour Tools API gives developers REST access to the same converters, SEO utilities, documents, and AI tools available on the website. Sign up for a free account, generate an API key, and integrate endpoints into your product.

  • How much does the API cost?

    Every developer account includes 500 free API requests per month. Paid plans with higher limits are on our pricing page. Browser tools remain free with no account.

  • How do I get an API key?

    Create a free developer account, verify your email, then open Dashboard → API Keys to generate a key. Keys use the ty_ prefix.

  • Do I need an account to use tools in the browser?

    No. Our free online tools work instantly in the browser without signup. Developer accounts are only required for API access and usage tracking.

  • What can I integrate via the API?

    File converters (PDF, image, video, audio), SEO audits, document tools, text utilities, unit converters, finance calculators, and AI utilities — with more categories added over time.

  • Are browser tools and API the same engine?

    Yes. ToolYour runs one platform — browser tools for quick tasks, REST API for products and automation. Same capabilities, different access modes.
