The fine print

License note: Free. The API needs no licence for academic, commercial or any other use. The conditions say "A license is required for commercial download and installation of most Genome Browser binaries and source code"; that commercial licence covers downloading and installing binaries and source code, not the API, and is not a paid API tier. Tracks can carry their own conditions. Signal Lab links only.

Verdict

A genome-annotation source for region lookups, alongside ensembl-rest-api. Licence: Custom: the licence page says "No license or permission is needed to use the website, API and public MySQL server for academic, commercial or any other use". The conditions say "A license is required for commercial download and installation of most Genome Browser binaries and source code"; that licence is for binaries and source code, not the API, and is not a paid API tier. Individual tracks can carry their own source conditions. Rate limits: the API docs say "We generally recommend a maximum of one hit every second, but there is no strict limit on queries using the API." Signal Lab links only.
