    LanguageTool offers a tiered API pricing model based on daily call volume.
    A free public tier is available for development and low-volume use with no
    API key required. Paid API plans are sold as monthly subscriptions with
    no long-term commitment. All prices include VAT. Enterprise volumes beyond
    10,000 calls/day require custom pricing. Self-hosted deployments are
    available via the open-source LGPL-licensed codebase on GitHub.

      The full LanguageTool source code is open source under LGPL-2.1.
      Organizations can self-host to avoid per-call API fees. Automated
      or batch use cases are encouraged to use self-hosted instances
      rather than the public API.

  costOptimization:
    - tip: Use self-hosted LanguageTool for high-volume or batch workloads

    - tip: Split large documents into chunks under 60,000 characters for paid API
    - tip: Cache results for repeated identical texts to reduce API call count
    - tip: Use the free public API for development and testing before upgrading
    - tip: Select annual billing where available to reduce per-month cost
