Engine Configuration Options


Give your Engine a unique name. Remember that this name you choose will be visible on the Engines page.

Note: If you use the copyrighted name of a publicly available product, during the Verification process PolySwarm will require you to provide proof that you have rights to use that name.


If you haven’t already created a webhook in your Account Settings, you can create one here. However, it is best practice to create the webhook in your Account Settings first, so that you can test and verify it before associating it with an Engine. The Rate Limit on the webhook determines the maximum number of artifacts your Engine will accept per day.


Provide the URL of a website that has additional details about your Engine or your company.


PolySwarm recommends that you provide a description for your Engine. Think of it like a brief marketing description of your Engine and its capabilities. 1-2 sentences using 200 words or less is usually sufficient.

Max file size

Define the max size of artifacts that your engine can process. The PolySwarm Marketplace has an internal max file size, but this allows you to define your upper limit below the Marketplace limit.


All Microengines have the “microengine” tag. All Arbiters have the "arbiter" tag. All Engines that support “file” artifacts will have the “file” tag, and for “url” artifacts will have the “url” tag. Other than those required Tags, you are free to associate other Tags with your Engine. Most Engine owners select tags that are related to the types of files the Engine processes or types of technologies implemented in the Engine. Click the “Down Arrow” to see the list of available Tags.

Supported mimetypes

This is where you can define which types of files your Engine can process. If you leave this blank, the Marketplace will assume your Engine can process all files. Click the “Down Arrow” to see a list of available Mimetypes.

Table of Mimetypes by Category

This table should help you select which Mimetypes are appropriate for your Engine. We've grouped the available mimetypes into commonly referenced Categories.

Note: The mimetype application/octet-stream is a generic mimetype for a file that has binary content. Sometimes the mimetype detection cannot correctly select the exact mimetype of a file and will default to application/octet-stream. So, it is generally a good practice to select it if your Engine processes binary files.

Engine type

The only option right now is “Engine”. For Arbiters, PolySwarm will manually convert an Engine to an Arbiter during the on-boarding process.

Supported Artifact Types

Select “file” if your Engine can process files. Select “url” if your Engine processes URLs, domains, and IP addresses.
