Import Media from URL

import_media_from_url
Destructive

Import a media file from a public URL into Wistia, optionally into a folder, and track the asynchronous job status. Creates an Untitled Folder if no folder ID is given.

Instructions

This endpoint imports a media file from a given URL. The import is processed asynchronously and will return a background_job_status object rather than the typical Media response object. You can poll the background job status endpoint to check on the progress of the import.

If no folder_id is provided, a new folder called "Untitled Folder" will be created and the imported media will be placed there.

The URL must be publicly accessible : Wistia's servers need to be able to fetch the file directly.

Note: imports from certain domains (e.g. vimeo.com, wistia.com) are not permitted.

Requires api token with one of the following permissions

Read, update & delete anything

Tokens with the "Act with a team member's permissions" permission (all:delegate_to_contact_permissions scope) can also be used. Requests made with such a token are authorized using the permissions of the contact assigned to the token. Requires confirm=true for the requested mutation. May share access, notify people or incur provider charges.

Input Schema

NameRequiredDescriptionDefault
urlNoThe publicly accessible URL of the media file to import.
accountNoNamed private Wistia account; selects credentials, not a remote account ID.
confirmNoSet true only when the user asked for exactly this action.
payloadNoComplete JSON request body instead of body flags. Supports current nested customization, caption and nullable values.
folder_idNoThe hashed ID of the folder (project) to import the media into. If not provided, a new folder will be created.
payload_fileNoRegular local JSON body file, at most 5 MB. Cannot be mixed with body flags or payload.

TDQS

A4.1/5.0
Behavior4/5

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

Annotations already declare readOnly=false, destructive=true, idempotent=false and openWorld=true, but the description adds meaningful behavior: processing is asynchronous, a job-status object is returned instead of Media, polling is required, and a folder is auto-created when folder_id is omitted. The trailing permission/confirm boilerplate is generic, keeping this from a 5.

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 most important facts (import source, async return, folder default) are front-loaded and every early sentence earns its place. The permission/token and 'may share access, notify people or incur provider charges' block at the end is boilerplate that dilutes the otherwise tight structure.

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

Completeness4/5

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

With no output schema, the description correctly compensates by explaining the async job-status return and the need to poll. Combined with the domain restrictions and folder behavior, an agent has what it needs to invoke correctly, though failure/cloning edge cases are left unspecified.

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 coverage is 100%, so the schema already documents url, folder_id, confirm, account, payload and payload_file. The description restates the folder_id default ('Untitled Folder') and the URL accessibility requirement, but adds little that isn't already in the schema descriptions, so the baseline 3 applies.

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?

States a specific verb and resource ('imports a media file from a given URL') and distinguishes the operation from siblings like upload_media_file by scope (remote URL vs. local file). It also clarifies the returned payload is a background_job_status object rather than the typical Media object, which removes ambiguity about what this tool produces.

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?

Gives clear conditions for use: the URL must be publicly accessible and certain domains (vimeo.com, wistia.com) are not permitted, plus the folder_id default behavior. It doesn't explicitly name an alternative sibling (e.g. upload_media_file) for the local-file case, so it stops just short of full when-not guidance.

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