Metasmoke offers a JSON API to access data about posts, reasons, and feedback. This is the documentation for said API.

Getting Started

To get started, you’ll need an API key. No application can use the API without a key - you’ll get a 403 response. To get a key, ping a metasmoke admin in chat - they’ll be able to register one for you. Have a name in mind for your app - a name is necessary to register a key. You can edit it later, so it doesn’t have to be final. Also make sure that you have an active metasmoke account - this allows the registering admin to tie the key to your account, giving you control of your app.

Once you have your key, you should include it as the key query string parameter on all requests to the API.


The metasmoke API supports parameter-based filters (like the Stack Exchange API) so that you can filter a response down to only the fields you want.

To create a filter, visit and select the fields you want in the response. Only select the fields you need. Selecting fields from unrelated tables may break things.

N.B.: You can calculate filters yourself if you really want to, but you should have a thorough understanding of how to do so first. Ask ArtOfCode if you’re unsure.

Once you’ve got your filter, include it as the filter parameter on requests to the API that use it.

Write Methods

Write methods additionally require you to go through OAuth to get hold of a write token, which can be used to authorize the write request. You should follow this flow:

Write tokens do not expire and can be used to authorize as many requests as you need. If you get a 401 Unauthorized response when you included a write token, that token has likely been revoked by an administrator or by the user, and you need to go through OAuth again.
