createVideo

Generate a short video clip from a source image and a motion text prompt (image-to-video); a source image is required - to make a video from text alone, first createImage and animate that, or use createVideoFromReferences with reference images. Griffin (default, 480p) and Griffin HD (720p) both generate a soundtrack; no separate audio step is needed. The job result is the video URL and its actual duration in seconds. Optionally pass final_image to interpolate between a start and end frame. The chosen model and duration must be compatible (incompatible combinations return HTTP 400); see the model and duration fields for the values each model accepts. Credits are held when the job is accepted; the final charge is max(rate × produced seconds, the model's minimum charge), never more than for the duration you requested, and the difference (or everything, if the job fails or is cancelled) is refunded. Pass an optional request_id to tag the result so you can locate it later via listGenerations (type video). Related tools: use createImage for static images, animateSprite for sprite-sheet animation, and listGenerations (type video) to list videos you generated earlier. Async generation job: returns {id, status} - poll getApiJob (job and credit contract: see the server instructions).

Credits: credits/s × seconds, per model: Griffin 1.5/s (shortest duration 5s, so 7.5 credits minimum), Griffin HD 2/s (shortest duration 5s, so 10 credits minimum), Blitz 1/s (shortest duration 2s, so 2 credits minimum) [LEGACY], Eagle 1.3/s [LEGACY], Eagle with Audio 1.8/s [LEGACY]; [LEGACY] models are scheduled for removal - do not use them for new work; see this endpoint's full pricing table in the API docs.

TDQS

A4.8/5.0

Behavior5/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description carries full behavioral burden and handles it well: it discloses async job behavior, polling via getApiJob, generation of a soundtrack, credit hold/refund semantics, model/duration compatibility errors, and legacy model removal status. This far exceeds the minimum needed for safe invocation.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is long, but it is front-loaded with the core purpose and required input, and nearly every sentence carries operational value. It loses a point for density and some overlap with schema-level details, but it remains well-structured and useful.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the tool's complexity — async generation, pricing, compatibility rules, and many sibling tools — the description is remarkably complete. It covers prerequisites, alternatives, return shape, job polling, refund behavior, and result lookup, so an agent has everything needed to invoke it correctly.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters4/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema coverage is 100%, so the baseline is 3, but the description adds meaningful semantic context: it explains why model/duration compatibility matters, gives per-model credit costs, notes the effect of optional final_image interpolation, and clarifies request_id's role in locating results via listGenerations. It does not fully re-explain every parameter, but that is acceptable since the schema already covers them.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description opens with a specific verb and resource: 'Generate a short video clip from a source image and a motion text prompt (image-to-video)', and explicitly states that a source image is required. It also differentiates itself from siblings by naming createVideoFromReferences, createImage, and animateSprite as alternatives.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

It gives explicit when-to-use guidance: use this tool when you have a source image and motion prompt. It also tells the agent what to do for text-only video ('first createImage and animate that, or use createVideoFromReferences with reference images') and names related tools for static images and sprite animation.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
