text_to_video_create_video

What this API does

Create the same Text To Video you can make in the browser, but programmatically, so you can automate it, run it at scale, or connect it to your own app or workflow.

Good for

Automation and batch processing
Adding text to video into apps, pipelines, or tools

How it works (3 steps)

Upload your inputs (video, image, or audio) with Generate Upload URLs and copy the file_path.
Send a request to create a text to video job with the basic fields.
Check the job status until it's complete, then download the result from downloads.

Key options

Inputs: usually a file, sometimes a YouTube link, depending on project type
Resolution: free users are limited to 576px; higher plans unlock HD and larger sizes
Extra fields: e.g. face_swap_mode, start_seconds/end_seconds, or a text prompt

Cost
Credits are only charged for the frames that actually render. You'll see an estimate when the job is queued, and the final total after it's done.

For detailed examples, see the product page.

MCP guidance:

This starts an async video generation job and returns id plus credits_charged immediately. If the user wants the finished result, call the wait_for_video_project helper with the returned id, or poll the matching GET /v1/video-projects/{id} endpoint until status is complete, error, or canceled. Completed projects include downloads with direct URLs. The custom wait helper also returns exact_download_urls separately from expiration metadata.

First observedSep 1, 2026

TDQS

A4.4/5.0

Behavior5/5

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

With no annotations provided, the description carries the full behavioral burden and does so thoroughly. It discloses the async lifecycle: 'starts an async video generation job and returns id plus credits_charged immediately,' explains that the caller should 'wait_for_video_project' or poll until status is complete, and clarifies that 'completed projects include downloads with direct URLs.' It also discloses cost behavior: 'Credits are only charged for the frames that actually render.'

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 well-structured with bold section headers, bullet points, and a 'How it works' workflow, making it approachable and front-loaded. It is longer than strictly necessary—some sections overlap, and the 'Good for' list partly restates the opening—but the structure earns its length given the complexity of an async job-based video generation API.

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?

The description is complete for an async video-creation tool: it covers the upload step, the job creation step, polling/waiting for completion, result downloads, resolution limitations, and credit estimation. It also points to relevant documentation links and the custom wait helper, so an agent has everything needed to invoke the tool and retrieve the final output.

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

Parameters3/5

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

Schema description coverage is 88%, so the schema already explains most parameters thoroughly. The description adds some contextual meaning, such as resolution plan limits and the availability of extra fields, but it also includes a questionable detail: 'free users are limited to 576px,' which conflicts with the schema's stated 480p/720p defaults. It does not meaningfully compensate beyond the schema's rich per-model parameter documentation.

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 clear, specific statement: 'Create the same Text To Video you can make in the browser, but programmatically.' It identifies the resource, the action, and the value proposition. It is immediately distinguishable from siblings like image_to_video_create_video or video_to_video_create_video via the explicit 'text to video' framing.

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

Usage Guidelines4/5

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

The description provides clear context for when the tool is appropriate: 'Good for automation and batch processing' and 'Adding text to video into apps, pipelines, or tools.' It does not explicitly say when not to use it or name alternatives, so it falls short of the highest bar, but the intended usage context is clearly communicated.

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