Introduction

Welcome to the Hybrid API! You can use the API to programmatically create projects and run tasks. All you need is your API key and funds in your account.

Example

Let’s walk through an example using Hybrid to categorize companies. If you’re currently signed in, we’ve already included your own API key in all the examples so you can run them yourself.

First, let’s create a “categorize website” project. Note: it’s also possible to create the project in the web UI, and add tasks to it through the API.

require 'httparty'

# Create the project.
response = HTTParty.post("https://www.gethybrid.io/api/projects", 
  basic_auth: { username: "{{YOUR_API_KEY}}" },
  body: {
    name: "Categorize this website",
    payment_per_response: 0.10,
    questions: [
      {
        "text": "What is the name of the company at this website?"
      },
      {
        "text": "What category does this company belong to?",
        "options": ["Tech", "Sports", "Gaming"]
      }
    ]
  }
)

# Extract the project ID.
project_id = JSON.parse(response.body)["id"]

import requests

response = requests.post("https://www.gethybrid.io/api/projects", 
  auth = ("{{YOUR_API_KEY}}", ""),
  json = {
    "name": "Categorize this website",
    "payment_per_response": 0.10,
    "questions": [
      {
        "text": "What is the name of the company at this website?"
      },
      {
        "text": "What category does this company belong to?",
        "options": ["Tech", "Sports", "Gaming"]
      }
    ]
  }
)

# Extract the project ID.
project_id = response.json()["id"]

# See the Python and Ruby tabs instead.

Next, let’s add some tasks to the project. Once a task is added, it gets immediately sent to workers.

Here, we’re creating a task where workers will categorize “google.com”.

Note: by default, workers will see all task fields. If you’d like to customize the layout of the fields (e.g., to create images or urls), then you can pass in a fields_template when creating the project; see the Create a project endpoint.

# Add a task to the project.
HTTParty.post("https://www.gethybrid.io/api/projects/#{project_id}/tasks",
  basic_auth: { username: "{{YOUR_API_KEY}}" },
  body: {
    "fields": {
      "website": "google.com"
    }    
  }
)

# Add a task to the project.
requests.post("https://www.gethybrid.io/api/projects/%s/tasks" % project_id,
  auth = ("{{YOUR_API_KEY}}", ""),
  json = {
    "fields": {
      "website": "google.com"
    }    
  }
)

Finally, we can retrieve the results once completed. You can also download the results as a CSV or spreadsheet in the UI.

# Retrieve all the tasks in the project and their responses.
response = HTTParty.get("https://www.gethybrid.io/api/projects/#{project_id}/tasks",
  basic_auth: { username: "{{YOUR_API_KEY}}" }
)

JSON.parse(response.body).each do |task|
  puts task["responses"][0]["data"]
end

# Retrieve all the tasks in the project and their responses.
response = requests.get("https://www.gethybrid.io/api/projects/%s/tasks" % project_id,
  auth = ("{{YOUR_API_KEY}}", "")
)

for task in response.json():
  print task["responses"][0]["data"]

Authentication

To authorize, use this code.

require 'httparty'

# For POST requests
HTTParty.post("{{API_ENDPOINT}}", 
  basic_auth: { username: "{{YOUR_API_KEY}}" },
  body: {
    ... # Parameters in the POST request
  }
)

# For GET requests
HTTParty.get("{{API_ENDPOINT}}", 
  basic_auth: { username: "{{YOUR_API_KEY}}" }
)

import requests

# For POST requests
requests.post("{{API_ENDPOINT}}", 
  auth = ("{{YOUR_API_KEY}}", ""),
  json = {
    ... # Parameters in the POST request
  }
)

# For GET requests
requests.get("{{API_ENDPOINT}}", 
  auth = ("{{YOUR_API_KEY}}", "")
)

# Note that the colon follows the API key and is not part of it.
curl {{API_ENDPOINT}} \
  -u {{YOUR_API_KEY}}:

Hybrid uses API keys to allow access to the API. You can find your API key in your profile.

Authentication is performed via HTTP Basic Auth. Your API key is your basic auth username, and you do not need to provide a password.

If you need to authenticate via bearer auth (e.g., for a cross-origin request), use -H "Authorization: {{YOUR_API_KEY}}:" instead of -u {{YOUR_API_KEY}}:.

Parameters

Parameter Type Description
name string Name to give your project. (required)
payment_per_response float Amount in dollars to pay workers for each response. (required)
questions array An array of JSON objects that define the questions that are shown to workers. Each question object takes a text field (the question that gets shown to workers), an optional options array (for multiple_choice and checkbox, which define the answer options that workers see), an optional type field (one of free_response, multiple_choice, bounding_box, or checkbox; by default, if the field is not provided, then question objects without options are assumed to be free_response, and question objects with options are assumed to be multiple_choice), and an optional required field (a boolean that defines whether or not the question must be answered; default true). (required)
callback_url string URL where completed tasks will be POSTed. (optional, default null)
fields_template string An HTML mustache template that defines how task fields are presented to workers. For example, if the task contains a “first_name” and a “last_name”, then the mustache template might be “Name: {{first_name}} {{last_name}}”, and workers would see something like “Name: John Smith”. (optional, defaults to a named list of the fields passed into the task)
num_workers_per_task integer Number of workers who work on each task. (optional, default 1)
