The on-prem container currently uses
/api/v1/marker. The new dedicated endpoints (/convert, /extract, /segment) will be available in a future container release.Supported endpoints
The container currently supports:/api/v1/markerdocumented here. This uses both the Marker and Chandra models./api/v1/ocrdocumented here./api/v1/usagedocumented here — provides usage analytics and performance metrics for your on-prem deployment.
Authentication
API authentication is not supported in the container. We assume customers will be running our image on their own infrastructure in private networks. You may send theX-API-Key header detailed here, but it will be ignored and any value works.
PDFs and images are supported, document conversion not yet supported
Datalab’s API supports many file types. The container currently supports PDFs and image file types. Other file types are not yet supported, but will be supported in an upcoming release.Feature Parity
