What the VerseDB API may be used for, and when commercial use needs a VerseDB Developers plan.
This API is intended for integration, automation, and building tools that enhance the VerseDB experience. Bulk crawling, mirroring the dataset, or building competing databases is not permitted without prior approval. High-volume access should leverage caching and conditional requests.
Without a license the API is for non-commercial use (Terms of Service, Section 12). Commercial use needs a VerseDB Developers plan, which gives an organization keys on a shared allowance under the VerseDB Developers Terms.
