Mock sample for your project: DEV API (beta)

API for GNU Social-compatible microblogging server

Description of Instagram RESTful API.
Current limitations:
Instagram service does not support cross origin headers
for security reasons, therefore it is not possible to use Swagger UI and make API calls directly from browser.
Modification API requests (POST, DELETE) require additional security scopes
that are available for Apps created on or after Nov 17, 2015 and
started in Sandbox Mode.
Consider the Instagram limitations for API calls that depends on App Mode.
Warning: For Apps created on or after Nov 17, 2015 API responses
containing media objects no longer return the data field in comments and likes nodes.

All endpoints that don't require authentication are CORS enabled.
Dates and date times, unless otherwise specified, must be in
the RFC 3339 format.

This page contains the documentation on how to use Discourse through API calls.
> Note: For any endpoints not listed you can follow the
reverse engineer the Discourse API
guide to figure out how to use an API endpoint.
Request Content-Type
The Content-Type for POST and PUT requests can be set to application/x-www-form-urlencoded,
multipart/form-data, or application/json.
Endpoint Names and Response Content-Type
Most API endpoints provide the same content as their HTML counterparts. For example
the URL /categories serves a list of categories, the /categories.json API provides the
same information in JSON format.
Instead of sending API requests to /categories.json you may also send them to /categories
and add an Accept: application/json header to the request to get the JSON response.
Sending requests with the Accept header is necessary if you want to use URLs
for related endpoints returned by the API, such as pagination URLs.
These URLs are returned without the .json prefix so you need to add the header in
order to get the correct response format.
Authentication
Some endpoints do not require any authentication, pretty much anything else will
require you to be authenticated.
To become authenticated you will need to create an API Key from the admin panel.
Once you have your API Key you can pass it in along with your API Username
as an HTTP header like this:
Boolean values
If an endpoint accepts a boolean be sure to specify it as a lowercase
true or false value unless noted otherwise.

The PeerTube API is built on HTTP(S) and is RESTful. You can use your favorite
HTTP/REST library for your programming language to use PeerTube. The spec API is fully compatible with
openapi-generator
which generates a client SDK in the language of your choice - we generate some client SDKs automatically:
Python
Go
Kotlin
See the REST API quick start for a few
examples of using the PeerTube API.
Authentication
When you sign up for an account on a PeerTube instance, you are given the possibility
to generate sessions on it, and authenticate there using an access token. Only __one
access token can currently be used at a time__.
Roles
Accounts are given permissions based on their role. There are three roles on
PeerTube: Administrator, Moderator, and User. See the roles guide for a detail of their permissions.
Errors
The API uses standard HTTP status codes to indicate the success or failure
of the API call, completed by a RFC7807-compliant response body.
Where id is the name of the field concerned by the error, within the route definition.
invalid-params..location can be either 'params', 'body', 'header', 'query' or 'cookies', and
invalid-params..value reports the value that didn't pass validation whose invalid-params..msg
is about.
Deprecated error fields
Some fields could be included with previous versions. They are still included but their use is deprecated:
error: superseded by detail
code: superseded by type (which is now an URI)
Rate limits
We are rate-limiting all endpoints of PeerTube's API. Custom values can be set by administrators:
| Endpoint (prefix: /api/v1) | Calls | Time frame |
|------------------------------|---------------|--------------|
| /* | 50 | 10 seconds |
| POST /users/token | 15 | 5 minutes |
| POST /users/register | 2 * | 5 minutes |
| POST /users/ask-send-verify-email | 3 | 5 minutes |
Depending on the endpoint, * failed requests are not taken into account. A service
limit is announced by a 429 Too Many Requests status code.
You can get details about the current state of your rate limit by reading the
following headers:
| Header | Description |
|-------------------------|------------------------------------------------------------|
| X-RateLimit-Limit | Number of max requests allowed in the current time period |
| X-RateLimit-Remaining | Number of remaining requests in the current time period |
| X-RateLimit-Reset | Timestamp of end of current time period as UNIX timestamp |
| Retry-After | Seconds to delay after the first 429 is received |
CORS
This API features Cross-Origin Resource Sharing (CORS),
allowing cross-domain communication from the browser for some routes:
| Endpoint |
|------------------------- ---|
| /api/* |
| /download/* |
| /lazy-static/* |
| /live/segments-sha256/* |
| /.well-known/webfinger |
In addition, all routes serving ActivityPub are CORS-enabled for all origins.
