# API Reference

PluralKit has a basic HTTP REST API for querying and modifying your system. The root endpoint of the API is https://api.pluralkit.me/v2/.

# Authorization header token example

Authorization: z865MC7JNhLtZuSq1NXQYVe+FgZJHBfeBCXOPYYRwH4liDCDrsd7zdOuR45mX257

Endpoints will always return all fields, using null when a value is missing. On PATCH endpoints, missing fields from the JSON request will be ignored and preserved as is, but on POST endpoints will be set to null or cleared.

For models that have them, the keys id, uuid and created are not user-settable.

Endpoints taking JSON bodies (eg. most PATCH and PUT endpoints) require the Content-Type: application/json header set.

# User agent

The API requires the User-Agent header to be set to a non-empty string. Not doing so will return a 400 Bad Request with a JSON body.

If you are developing an application exposed to the public, we would appreciate if your User-Agent uniquely identifies your application, and (if possible) provides some contact information for the developers - so that we are able to contact you if we notice your application doing something it shouldn't.

# Authentication

Authentication is done with a simple "system token". You can get your system token by running pk;token using the Discord bot, either in a channel with the bot or in DMs. Then, pass this token in the Authorization HTTP header on requests that require it. Failure to do so on endpoints that require authentication will return a 401 Unauthorized.

Some endpoints show information that a given system may have set to private. If this is a specific field (eg. description), the field will simply contain null rather than the true value. If this applies to entire endpoint responses (eg. fronter, switches, member list), the entire request will return 403 Forbidden. Authenticating with the system's token (as described above) will override these privacy settings and show the full information.

# Rate Limiting

By default, there is a per-IP limit of 2 requests per second across the API. If you exceed this limit, you will get a 429 response code and will have to try again later.

The following rate limit headers are present on HTTP responses:

name description
X-RateLimit-Limit The amount of total requests you have available per second.
X-RateLimit-Remaining The amount of requests you have remaining until the next reset time.
X-RateLimit-Reset The UNIX time (in milliseconds) when the ratelimit info will reset.

If you make more requests than you have available, the server will respond with a 429 status code and a JSON error body.

  "message": "429: too many requests",
  "retry_after": 19, // the amount of milliseconds remaining until you can make more requests
  "code": 0
