Mock sample for your project: DEV API (beta)

The spoonacular Nutrition, Recipe, and Food API allows you to access over 380,000 recipes, thousands of ingredients, 80,000 food products, and 100,000 menu items. Our food ontology and semantic recipe search engine makes it possible to search for recipes using natural language queries, such as "gluten free brownies without sugar" or "low fat vegan cupcakes." You can automatically calculate the nutritional information for any recipe, analyze recipe costs, visualize ingredient lists, find recipes for what's in your fridge, find recipes based on special diets, nutritional requirements, or favorite ingredients, classify recipes into types and cuisines, convert ingredient amounts, or even compute an entire meal plan. With our powerful API, you can create many kinds of food and especially nutrition apps.
Special diets/dietary requirements currently available include: vegan, vegetarian, pescetarian, gluten free, grain free, dairy free, high protein, whole 30, low sodium, low carb, Paleo, ketogenic, FODMAP, and Primal.

API for GNU Social-compatible microblogging server

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.
