Features and tool support

TokenRex’s exposed interface, not every feature advertised by the provider. “Available” describes the implemented interface, not a successful test of every input or tool.

Available

Text prompt (and optional start image) on POST /v1/videos.

Output through TokenRex

Available

A job id you check on /v1/videos/{id}; the finished MP4 downloads from /v1/videos/{id}/content.

Function tools

Not exposed

Video endpoint only — it creates videos and does not run tools.

Sources and verification

Provider specifications describe the upstream model, not a guarantee of every feature through TokenRex. Prices come from the enabled catalog; benchmark results belong to the exact tested model.

Research notes (3)
  • These durations and resolutions are accepted by the TokenRex endpoint; they are not fresh generation measurements.
  • TokenRex does not expose provider video extension, reference-image arrays or first/last-frame controls.
  • TokenRex’s endpoint requires 8 seconds for 1080p and 4K; this is its validation rule, not a claim about every upstream interface. Unsupported duration values are normalized to 8 seconds.
