Introduction

Welcome to the Algorithmia API documentation! You can use the API to access any algorithm in the marketplace.

We have clients & libraries in multiple languages. We encourage you to click on the different language tabs at the top of the right-side pane to see code samples in your language of choice.

This documentation will serve as a reference as you start to integrate the Algorithmia API into your code.

If this is your first time trying Algorithmia, you might find it useful to start with our Getting Started guide, which can be found alongside many other resources in the Algorithmia Developer Center.

Authentication

API Keys

To authorize, use this code:

# With shell, you can just pass the correct header with each request
curl "api_endpoint_here" -H 'Authorization: Simple YOUR_API_KEY'

$ algo auth
Configuring authentication for 'default' profile
Enter API Key (prefixed with 'sim'): YOUR_API_KEY
Profile is ready to use. Test with 'algo ls'

import Algorithmia

client = Algorithmia.client('YOUR_API_KEY')

library(algorithmia)

client <- getAlgorithmiaClient('YOUR_API_KEY')

require 'algorithmia'

client = Algorithmia.client('YOUR_API_KEY')

import com.algorithmia.*;
import com.algorithmia.algo.*;

AlgorithmiaClient client = Algorithmia.client("YOUR_API_KEY");

import com.algorithmia._
import com.algorithmia.algo._

val client = Algorithmia.client("YOUR_API_KEY")

extern crate algorithmia
use algorithmia::*;
use algorithmia::algo::*;

let client = Algorithmia::client("YOUR_API_KEY");

// include the algorithmia.js library
// https://algorithmia.com/v1/clients/js/algorithmia-0.2.0.js

var client = Algorithmia.client('YOUR_API_KEY');

var client = Algorithmia.client('YOUR_API_KEY');

<?
$client = Algorithmia::client("YOUR_API_KEY");
?>

Make sure to replace YOUR_API_KEY with your API key.

API requests are authenticated by a key which can be found and managed from your user profile. With every call to the API, the user must be authenticated. The API has a simple means to do this by passing in your key as an HTTP “Authorization” header with the request.

When you signed up for Algorithmia, a ‘default-key’ was generated for your convenience. This is the key that is used throughout the example code within algorithm pages. For these examples to work correctly, this default key must exist with all the permissions, otherwise the usage examples may result in a 401 Unauthorized error.

Key Restrictions

Algorithmia provides you with fine-grained controls for restricting what API calls can be made with a specific key from the Credentials section of your user profile.

You can create or modify any key to include any or all of the following restrictions:

API Specification

The Algorithmia API gives developers the ability to build applications that interact with and use all the features of Algorithmia in an automated fashion. Tasks can be generated, work can be ordered, and your application can be notified as data is processed by Algorithmia.

Requests to the API must be formatted in JSON. We follow the JSON-RPC 2.0 spec.

A properly formatted request will always return the HTTP status code 200 OK; with either a result field (which may be null in some cases) for successes or an error field to indicate failure.

The size limit for a request is 10MiB. Check out the Data API for options on how to process larger files.

Call an Algorithm

curl -X POST -H 'Authorization: Simple YOUR_API_KEY' \
    -d 'YOUR_NAME' -H 'Content-Type: text/plain' \
    https://api.algorithmia.com/v1/algo/demo/Hello/

$ algo run -d 'YOUR_NAME' demo/Hello/
Hello YOUR_NAME

import Algorithmia

input = "YOUR_NAME"
client = Algorithmia.client('YOUR_API_KEY')
# Pass in the unique algoUrl path found on each algorithm description page.
algo = client.algo('demo/Hello/')
# Calls an algorithm with the input provided.
result = algo.pipe(input)

# If you are using the 1.0+ client you can access both the output and the metadata.
print(result.result)    # Hello YOUR_NAME
print(result.metadata)  # Metadata(content_type='text',duration=0.0002127)

library(algorithmia)

input <- "YOUR_NAME"
client <- getAlgorithmiaClient('YOUR_API_KEY')
algo <- client$algo('demo/Hello/')
result <- algo$pipe(input)$result
print(result)

require 'algorithmia'

client = Algorithmia.client('YOUR_API_KEY')

use algorithmia::*;
use algorithmia::algo::*;

let client = Algorithmia::client("YOUR_API_KEY");
let algo = client.algo("algo://demo/Hello/");

// include the algorithmia.js library
// https://algorithmia.com/v1/clients/js/algorithmia-0.2.0.js

var input = "YOUR_NAME";
Algorithmia.client("YOUR_API_KEY");

client.algo("algo://demo/Hello/")
      .pipe(input)
      .then(function(output) {
        console.log(output);
      });

var algorithmia = require("algorithmia");

var input = "YOUR_NAME";

       });

<?
require_once "vendor/autoload.php";

$input = "YOUR_NAME";
$client = Algorithmia::client("YOUR_API_KEY");
$algo = $client->algo("demo/Hello/0.1.0");
echo $algo->pipe($input)->result;
?>

Make sure to replace YOUR_NAME with your name & YOUR_API_KEY with your API key.

For each algorithm on the marketplace, you’ll find an owner (the user who created the algorithm), an algorithm name, and a version number. Algorithms are called using this HTTP endpoint:

POST https://api.algorithmia.com/v1/algo/:owner/:algoname/[:version]

Specifying a version is recommended, but optional. If not specified, the latest publicly published version will be used. When explicitly specifying a version, the following following formats are accepted:

Version Description
1.1.1 Fully specified version
1.2.* Specified to the minor level. Will resolve to the latest publicly published version with a minor version of 1.2
1.* Specified to a major version. Will resolve to the latest publicly published version with major version 1

Algorithmia supports calling algorithms that use any combination of text, JSON, or binary as their input and output.

Each client SDK provides idiomatic abstractions for calling algorithms using common native types and automatic serialization and deserialization where reasonable. See the code samples to the right for examples in the language of your choice.

HTTP input specification

To specify input when making a raw HTTP request, the body of the request is the input to the algorithm you are calling. To specify the input type, set the Content-Type header accordingly. These are

Content-Type Description
application/json body specifies JSON input data (UTF-8 encoded)
application/text body specifies text input data (UTF-8 encoded)
application/octet-stream body specifies binary input data (raw bytes)

HTTP output specification

The metadata.content_type specifies which type of encoding the result element is in.

Content-Type Description
void The result element is null
text The result element is a JSON string using UTF-8 encoding
json The result element is any valid JSON type
binary The result element is a Base64 encoded binary data in a JSON String

The API also provides the following configurable parameters when calling an algorithm:

Parameter Description
timeout number: Specifies a timeout for the call in seconds. default=300 (5min), max=3000 (50min)
stdout boolean: Indicates algorithm stdout should be returned in the response metadata (ignored unless you are the algorithm owner)
output raw or void: Indicates the format for returned data

Error Handling

Error Handling

curl -X POST -H 'Authorization: Simple YOUR_API_KEY' \
    -d '[]' -H 'Content-Type: application/json' \
    https://api.algorithmia.com/v1/algo/demo/Hello/

} catch (Algorithmia\AlgoException $x) {
    echo $x;
}
// -> Algorithmia\\AlgoException: algorithm algo://util/whoopsWrongAlgo not found
?>

If an error occurs, an Exception will be raised/thrown (Java, Python, PHP, R, Ruby, Rust, Scala) or the response be modified (JavaScript, NodeJS) to contain the following fields:

Field Description
error.message The error message
error.stacktrace (Optional) a stacktrace if the error occurred within the algorithm (only if caller has access to algorithm source)

Each client provides a language-specific solution for error handling. The examples on the right come from calling an algorithm that expects text input in it’s implementation of the apply entrypoint, but instead receives a JSON array as input.

Data API Specification

/*
  The Javascript client does not currently have support for the Data API.
  Contact us if you need this feature and we'll prioritize it right away:
  https://algorithmia.com/contact

  Note: The NodeJS client does currently support the Data API.
*/

The Algorithmia Data API provides a way of getting data into and out of algorithms with support for Algorithmia Hosted Data as well as working directly with data in your Dropbox account or Amazon S3 buckets. For an introduction to working with data from these different data sources, see the data portal guides for Algorithm Developers or for Application Developers.

Data URI

A Data URI uniquely identifies files and directories. A Data URI is composed of a protocol and a path (e.g. data://.my/photos). Each connected data source has has a unique protocol. Supported protocols include:

Protocol Description
data:// Algorithmia hosted data
dropbox:// Dropbox default connected account
s3:// Amazon S3 default connected account

Additionally, if you connect multiple accounts from the same source, they can be uniquely identified by their label, e.g. dropbox+mylabel://.

The path part of a Data URI is understood in the context of each source:

URI Description
data://.my/foo The foo collection of your Algorithmia hosted data
dropbox://foo The foo file or directory in the root of your default Dropbox connected account
s3://foo The foo bucket of your S3 account

The remainder of this documentation provides the specification for working with directories and files regardless of what data source they come from.

Directories

Directories are a collection of files or other directories.

Listing a directory

Listing a directory:

# List top-level user directory
curl -H 'Authorization: Simple YOUR_API_KEY' \
    https://api.algorithmia.com/v1/connector/data/.my

-> {

    ]
}

# List a directory with ACLs
curl -H 'Authorization: Simple YOUR_API_KEY' \
    https://api.algorithmia.com/v1/connector/data/.my/robots?acl=true

-> {

Algorithm Development

As an Algorithmia user, in addition to having access to hundreds of algorithms, you also have the ability to add your own algorithms. You can write a private algorithm for your own use, contribute an open source algorithm, or monetize an algorithm you authored. Our algorithms and platform are designed with composability in mind, so think of algorithms in the marketplace as building blocks.

We currently support algorithm development in:

Algorithm Management

Using the Algorithmia API, you can create, publish, update, and inspect individual algorithms. At present, only our Python client supports algorithm management, and we’ve provided cURL examples for those algorithm management endpoints which our Python client does not yet support.

To try out a complete training-to-deployment pipeline, get the runnable Jupyter Notebook.

IMPORTANT:

  1. Before using these functions, update to the latest Python client: pip install -U Algorithmia

  2. Create a NEW API Key at https://algorithmia.com/user#credentials or in your own Algorithmia cluster, with the option “Allow this key to manage my algorithms” turned on. Do not use this key for other purposes.

First, define an algo using client.algo('USERNAME/ALGONAME'), making sure that “USERNAME/ALGONAME” is not the name of an existing Algorithm.

Then, call algo.create(details, settings) – the parameters are dictionaries with the following keys:

details:

settings:

Once this has been done, your algorithm will be visible at https://algorithmia.com/algorithms/USERNAME/ALGONAME … but it doesn’t have any code yet. You’ll need to git clone https://git.algorithmia.com/git/USERNAME/ALGONAME.git, then add and commit code, before continuing on to the Publishing step.

Update an Algorithm

algo.update(
    details = {
        "label": "Echo", #user-readable name of the algorithm
    },
    settings = {
        "source_visibility": "open",
        "license": "apl",
        "network_access": "full",
        "pipeline_enabled": True,
        "environment": "cpu"
    }

Once you’ve committed code, you can use algo.publish(details, settings, version_info) to make the Algorithm callable. All parameters are optional, and will overwrite those specified in the initial create() call if they conflict.

Note the addition of “algorithm_callability” to the settings parameter: if this is set to “public”, your Algorithm will be published publicly, allowing any registered user to call it.

Under version_info, even if your sample_input is a dictionary, it must be encapsulated as a string, such as "sample_input": "{\"text\": \"This is a very positive review for the movie. I absolutely loved it!\"}"
