LINDAT UDPipe API is one of 17 APIs that [Charles University](https://apis.io/providers/charles/) publishes on the [APIs.io](https://apis.io/) network, described by a machine-readable OpenAPI specification. Tagged areas include Natural Language Processing, Universal Dependencies, Parsing, and Research. The published artifact set on APIs.io includes an OpenAPI specification and API documentation.

Public keyless REST API for tokenization, part-of-speech tagging, lemmatization and dependency parsing of CoNLL-U data, operated by UFAL at Charles University. The live service advertised 961 Universal Dependencies models when probed on 2026-09-01. The OpenAPI here is derived by API Evangelist from the service's own published REST API reference and verified against live responses; UFAL publishes documentation, not a machine-readable contract.
