# Overview

{% hint style="info" %}
The v1 docs are here for reference to the older API. We are currently in the process of making changes to the [v2 documentation](https://docs.whisk.com/v/2.0.0/) for new features.

Graph API is the recommended way of interacting with the Whisk Platform. It is made as HTTP-based API, heavily inspired by Facebook Graph.

## The Basics

Whisk Graph is composed of:

* nodes - "things" like Recipe, User, Food, etc.
* edges - connections between nodes (Recipe includes multiple Food items)
* fields - details of node (Recipe instructions, urls)

The Graph API is HTTP-based, so it works with any language that has an HTTP library, such as cURL.

Most Graph API requests require the use of [access tokens](/master/api/auth.md).

## The Graph API

All requests are passed to the API at `graph.whisk.com`.

### Object IDs

Each node has a unique ID that is used to access it via the Graph API. Here's how you'd use the ID to make a request for a node:

```bash
curl "https://graph.whisk.com/v1/10343992" \
    -H "Accept: application/json" \
    -H "Authorization: Bearer <Access-Token>"
```

### URL Lookup

Most objects can be discovered using their IDs, but sometimes you have the only the URL of a resource. A canonical example is getting or extracting Recipe by url:

```bash
curl "https://graph.whisk.com/v1/?id=https%3A%2F%2Fwww.bbcgoodfood.com%2Frecipes%2Fomelette-pancakes-tomato-pepper-sauce" \
  -H "Accept: application/json" \
  -H "Authorization: Bearer <Access-Token>"
```

### Searching

You can search over multiple types with the `/search` endpoint:

```bash
curl "https://graph.whisk.com/v1/search?q=salmon&type=recipe&diet=paleo" \
  -H "Accept: application/json" \
  -H "Authorization: Bearer <Access-Token>"
```

### Multiple IDs request

We provide a convenient way to get a batch of different nodes. You can provide `?ids` parameter with the object IDs of those nodes. You also can use URLs with node ids simultaneously.

```bash
curl "https://graph.whisk.com/v1/?ids=10343992,https%3A%2F%2Fwww.bbcgoodfood.com%2Frecipes%2Fegg-fried-rice" \
  -H "Accept: application/json" \
  -H "Authorization: Bearer <Access-Token>"
```

It will return a response for each id or URL like this:

```javascript
{
  "10343992": {
    "field": "..."
  },
  "https://www.bbcgoodfood.com/recipes/egg-fried-rice": {
    "field": "..."
  }
}
```

### Cursor Pagination

Some of our endpoints provide cursor-based pagination. A cursor is a random string which points to a specific item in a list of data. A string pointed to an element can be changed in future. Therefore, your app should not store cursors.

```bash
curl "https://graph.whisk.com/v1/products/autocomplete?language=en&limit=5&after=eyJpZCI6IlBPUksgQkFCWSBCQUNLIFJJQiIsImluZGV4Ijo5fQ==" \
  -H "Accept: application/json" \
  -H "Authorization: Bearer <Access-Token>"
```

A result will contain segment with pagination which includes cursors to the first and the last item in the result. Reference will be empty if there are no elements before or after cursor.

Example of a segment with cursors:

```javascript
{
  "after": "eyJpZCI6IkNISUEgU0VFRFMiLCJpbmRleCI6MTR9",
  "before": "eyJpZCI6IkdSQU5PTEEiLCJpbmRleCI6MTB9"
}
```

### Limits

Some of our endpoints have limits:

* `POST /carts/checkout`, `POST /lists`, `POST /carts` and other endpoints accepting items can accept maximum 50 of them
* `POST /carts/checkout`, `POST /lists`, `POST /carts` and other endpoints accepting `recipes`can accept maximum 25 of them

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://docs.whisk.com/master/master.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
