audible.cr

Interface for internal Audible API.

Other Implementations

• Audible (Python)
• AudibleApi (C#)

See also AudiobookHub for a list of handy resources for managing audiobooks.

Installation

1. Add the dependency to your shard.yml:

dependencies:
  audible:
    github: omarroth/audible.cr

2. Run shards install

Usage

require "audible"

client = Audible::Client.new("EMAIL", "PASSWORD", locale: "us")
puts client.get("/1.0/library").body # => {"items":[{"asin":"B002V0QUOC"...

Sessions can be saved using to_json and from_json, like so:

require "audible"

client = Audible::Client.new("EMAIL", "PASSWORD", locale: "us")
File.write("session.json", client.to_json)

# Sometime later...
client = Audible::Client.from_json(File.read("session.json"))

Logging in currently requires answering a CAPTCHA. By default a user prompt will be provided using readline, which looks like:

https://opfcaptcha-prod.s3.amazonaws.com/...
Answer for CAPTCHA:

A custom callback can be provided (for example submitting the CAPTCHA to an external service), like so:

require "audible"

client = Audible::Client.new("EMAIL", "PASSWORD", locale: "us") do |captcha_url|
  # Do some things with the captcha_url ...

  "My answer for CAPTCHA"
end

If 2FA is enabled for the given account a prompt will be provided using readline, which looks like:

OTP Code:

A custom callback can be provided like so:

def custom_otp_callback
  # Do some things to get OTP code...

  return "My OTP code"
end

client = Audible::Client.new("USERNAME", "PASSWORD", locale: "us", otp_callback: ->custom_otp_callback)

# Or directly as proc:

client = Audible::Client.new("USERNAME", "PASSWORD", locale: "us", otp_callback: ->{ return "My OTP code" })

Locales

This API supports 5 countries natively:

• USA (locale: "us")
• Germany (locale: "de")
• United Kingdom (locale: "uk")
• France (locale: "fr")
• Canada (locale: "ca")

Authentication

Clients are authenticated using OpenID. Once a client has successfully authenticated with Amazon, they are given an access token and refresh token for authenticating with Audible.

Clients authenticate with Audible using cookies from Amazon and the given access token to /auth/register. Clients are given an RSA private key and adp_token used for signing subsequent requests.

For requests to the Audible API, requests need to be signed using the provided key and adp_token. Request signing is fairly straight-forward and uses a signed SHA256 digest. Headers look like:

x-adp-alg: SHA256withRSA:1.0
x-adp-signature: AAAAAAAA...:2019-02-16T00:00:01.000000000Z,
x-adp-token: {enc:...}

The Audible::Client will refresh the access_token and other necessary keys when necessary.

As reference for other implementations, a client must store cookies from a successful Amazon login and a working access_token in order to renew refresh_token, adp_token, etc from /auth/register.

An access_token can be renewed by making a request to /auth/token. access_tokens are valid for 1 hour.

Documentation:

There is currently no publicly available documentation about the Audible API. There is a node client (audible-api) that has some endpoints documented, but does not provide information on authentication.

Luckily the Audible API is partially self-documenting, however the parameter names need to be known. Error responses will look like:

{
  "message": "1 validation error detected: Value 'some_random_string123' at 'numResults' failed to satisfy constraint: Member must satisfy regular expression pattern: ^\\d+$"
}

Few endpoints have been fully documented, as a large amount of functionality is not testable from the app or functionality is unknown. Most calls need to be authenticated.

For %s substitutions the value is unknown or can be inferred from the endpoint. /1.0/catalog/products/%s for example requires an asin, as in /1.0/catalog/products/B002V02KPU.

Each bullet below refers to a parameter for the request with the specified method and URL.

Responses will often provide very little info without response_groups specified. Multiple response groups can be specified, for example: /1.0/catalog/products/B002V02KPU?response_groups=product_plan_details,media,review_attrs. When providing an invalid response group, the server will return an error response but will not provide information on available response groups.

Downloading

For multipart books, it's necessary to use the child_asin provided with response_groups=relationships in order to download each part.

require "audible"

client = Audible::Client.new("EMAIL", "PASSWORD")

# Request .aax file in given quality
body = {
  consumption_type: "Download",
  drm_type:         "Adrm",
  quality:          "Extreme",
}.to_json

content_url = JSON.parse(client.post("/1.0/content/B002V0QUOC/licenserequest", body: body).body)["content_license"]["content_metadata"]["content_url"]["offline_url"].as_s # => https://dyrrggeck87jc.cloudfr...

# `content_url` can then be downloaded using any tool

Note: content_url is now provided in .aaxc format, which ffmpeg does not currently support, see mkb79/Audible#3. For now you can use the following to get files in .aax format:

require "audible"

asin = "some_asin"
codec = "some_codec" # Desired quality from /1.0/library/{asin}?response_groups=product_attrs,relationships

client = Audible::Client.from_json(File.read("session.json"))

request = HTTP::Request.new("GET", "/FionaCDEServiceEngine/FSDownloadContent?type=AUDI&currentTransportMethod=WIFI&key=#{asin}&codec=#{codec}")
request = client.sign_request(request)

tld = Audible::LOCALES[client.locale]["AUDIBLE_API"].to_s.split("api.audible.")[1]
content_url = HTTP::Client.new(URI.parse("https://cde-ta-g7g.amazon.com")).exec(request)
  .headers["Location"].gsub("https://cds.audible.com", "https://cds.audible.#{tld}") # => https://cds.audible.com/download...

# `content_url` can then be downloaded using any tool

Assuming you have your activation bytes, you can convert .aax into another format with the following:

$ ffmpeg -activation_bytes 1CEB00DA -i test.aax -vn -c:a copy output.mp4
