Rettiwt-API
A CLI tool and an API for fetching data from Twitter for free!
Prerequisites
- NodeJS 20
- A working Twitter account (optional)
Installation
It is recommended to install the package globally, if you want to use it from the CLI. Use the following steps to install the package and ensure it's installed correctly:
- Open a terminal.
- Install the package using the command
npm install -g rettiwt-api
.
- Check if the package is installed correctly using the command
rettiwt help
.
For using the package in your own project, you can install it as a dependency.
Authentication
Rettiwt-API can be used with or without logging in to Twitter. As such, the two authentication strategies are:
By default, Rettiwt-API uses 'guest' authentication. If however, access to the full set of resources is required, 'user' authentication can be used. This is done by using the cookies associated with your Twitter/X account, and encoding them into an API_KEY
for convenience. The said API_KEY
can be obtained by using a browser extension, as follows:
A. For Chrome/Chromium-based browsers:
- Install the X Auth Helper extension from the Chrome Web Store, and allow it to run it in incognito mode.
- Switch to incognito mode and login to Twitter/X.
- After successful login, while still being on Twitter/X, click on the extension which will open the extension popup.
- Click on the
Get Key
button, this will generate the API_KEY
and will show up in the text-area.
- Copy the
API_KEY
by either clicking on the Copy Key
button or manually from the text-area.
- You may close the browser, but don't log out. Remember, since it's incognito mode, you didn't explicity 'log out', so, while the session will be erased from the browser, the
API_KEY
still remains valid.
- Save the
API_KEY
for use.
B. For Firefox/Firefox-based browsers:
- Install the Rettiwt Auth Helper extension from Firefox Add-Ons, and allow it to run it in in-private mode.
- Switch to in-private mode and login to Twitter/X.
- After successful login, while still being on Twitter/X, click on the extension which will open the extension popup.
- Click on the
Get API Key
button, this will generate the API_KEY
and will show up in the text-area.
- Copy the
API_KEY
by either clicking on the Copy API Key
button or manually from the text-area.
- You may close the browser, but don't log out. Remember, since it's in-private mode, you didn't explicity 'log out', so, while the session will be erased from the browser, the
API_KEY
still remains valid.
- Save the
API_KEY
for use.
Notes:
API_KEY
created in this way should last 5 years from the date of login, as long as the credentials to the account aren't changed.
- This approach can also be done without going into incognito/in-private mode, in which case you can either login as usual or skip the login step if you're already logged in, and continue from the steps after login. However, this makes the
API_KEY
to last only as long as the Twitter/X account isn't logged out of (you may exit the browser as usual) or 5 years, whichever comes first. That's why it's recommended to use incognito/in-private mode, so that the API_KEY
isn't accidentially revoked by logging out.
The API_KEY
The API_KEY generated by logging in is what allows Rettiwt-API to authenticate as a logged in user while interacting with the Twitter API ('user' authentication). As such it is a very sensitive information and therefore, must be stored securely. The following points must be kept in mind while using the API_KEY for 'user' authentication:
- The API_KEY is actually a base64 encoding of the account's cookies.
- The API_KEY provides the same level of authorization as any standard Twitter account, nothing more, nothing less.
Notes for non-programmers
- If you have no idea of programming, it's recommended to use the CLI.
- The CLI provides an easy to use interface which does not require any knowledge of JavaScript or programming
- Please skip to CLI-Usage for details.
Usage as a dependency
Rettiwt-API can be used as a dependency for your NodeJS project. In such a case, it is not required to install Rettiwt-API globally and you may install it locally in the root of your project using the command:
However, in this case, for accessing the CLI, you will be required to prepend the CLI commands with npx
in order to tell NodeJS to use the locally installed package.
The Rettiwt class
When used as a dependency, the Rettiwt class is entry point for accessing the Twitter API.
A new Rettiwt instance can be initialized using the following code snippets:
const rettiwt = new Rettiwt()
(for 'guest' authentication)
const rettiwt = new Rettiwt({ apiKey: API_KEY })
(for 'user' authentication)
The Rettiwt class has three members:
list
memeber, for accessing resources related to lists.
tweet
member, for accessing resources related to tweets.
user
member, for accessing resources related to users.
For details regarding usage of these members for accessing the Twitter API, refer to features.
Rettiwt Configuration
When initializing a new Rettiwt instance, it can be configures using various parameters, namely:
apiKey
(string) - The API key to use for user
authentication.
proxyUrl
(URL) - The URL to the proxy server to use.
timeout
(number) - The timeout to use for HTTP requests used by Rettiwt.
logging
(boolean) - Whether to enable logging or not.
errorHandler
(interface) - The custom error handler to use.
tidProvider
(interface) - The custom TID provider to use for generating transaction token.
headers
(object) - Custom HTTP headers to append to the default headers.
delay
(number/function) - The delay to use between concurrent requests, can either be a number in milliseconds, or a function that returns the number. Default is 0 (no delay).
maxRetries
(number) - The maximum number of retries to use in case when a random error 404 is encountered. Default is 0 (no retries).
Of these parameters, the following are hot-swappable, using their respective setters:
The following example demonstrates changing the API key on the fly:
import { Rettiwt } from 'rettiwt-api';
const rettiwt = new Rettiwt({ apiKey: '<API_KEY_1>' });
rettiwt.user.details().then((res) => {
console.log(res);
});
rettiwt.apiKey = '<API_KEY_2>';
rettiwt.user.details().then((res) => {
console.log(res);
});
Usage
The following examples may help you to get started using the library:
import { Rettiwt } from 'rettiwt-api';
const rettiwt = new Rettiwt();
rettiwt.user.details('<username>')
.then(details => {
...
})
.catch(error => {
...
});
import { Rettiwt } from 'rettiwt-api';
const rettiwt = new Rettiwt({ apiKey: API_KEY });
rettiwt.tweet.search({
fromUsers: ['<username>'],
includeWords: ['<word1>', '<word2>']
})
.then(data => {
...
})
.catch(err => {
...
});
For more information regarding the different available filter options, please refer to TweetFilter.
3. Getting the next batch of data using a cursor
The previous example fetches the the list of tweets matching the given filter. Since no count is specified, in this case, a default of 20 such Tweets are fetched initially. The following example demonstrates how to use the cursor string obtained from the response object's next field, from the previous example, to fetch the next batch of tweets:
import { Rettiwt } from 'rettiwt-api';
const rettiwt = new Rettiwt({ apiKey: API_KEY });
rettiwt.tweet.search({
fromUsers: ['<username>'],
includeWords: ['<word1>', '<word2>']
}, count, data.next.value)
.then(data => {
...
})
.catch(err => {
...
});
4. Getting an API_KEY during runtime, using 'user' authentication (Borked)
Sometimes, you might want to generate an API_KEY on the fly, in situations such as implementing Twitter login in your application. The following example demonstrates how to generate an API_KEY during runtime:
import { Rettiwt } from 'rettiwt-api';
const rettiwt = new Rettiwt();
rettiwt.auth.login('<email>', '<username>', '<password>')
.then(apiKey => {
...
})
.catch(err => {
console.log(err);
});
Where,
<email>
is the email associated with the Twitter account to be logged into.
<username>
is the username associated with the Twitter account.
<password>
is the password to the Twitter account.
Using a proxy
For masking of IP address using a proxy server, use the following code snippet for instantiation of Rettiwt:
const rettiwt = new Rettiwt({ apiKey: API_KEY, proxyUrl: PROXY_URL });
This creates a Rettiwt instance which uses the given proxy server for making requests to Twitter.
Debug logs
Sometimes, when the library shows unexpected behaviour, for troubleshooting purposes, debug logs can be enabled which will help in tracking down the issue and working on a potential fix. Currently, debug logs are printed to the console and are enabled by setting the 'logging' property of the config to true, while creating an instance of Rettiwt:
const rettiwt = new Rettiwt({ apiKey: API_KEY, logging: true });
Accessing raw response
For getting the raw data instead of the parsed results, all data models provide a getter raw
which returns the raw data entity as returned by Twitter, instead of parsing them to Rettiwt's own data entity formats. The following example demonstrates the use of the raw
getter:
import { Rettiwt } from 'rettiwt-api';
const rettiwt = new Rettiwt();
rettiwt.user.details('<username>')
.then(details => {
console.log(details);
console.log(details.raw);
})
.catch(error => {
...
});
However, if further control over the raw response is required, Rettiwt-API provides the FetcherService
class which provides direct access to the raw response, but keep in mind, this delegates the task of parsing and filtering the results to the consumer of the library. The following example demonstrates using the FetcherService
class:
import { RettiwtConfig, FetcherService, EResourceType, IUserDetailsResponse } from 'rettiwt-api';
const config = new RettiwtConfig({ apiKey: '<API_KEY>' });
const fetcher = new FetcherService(config);
fetcher
.request<IUserDetailsResponse>(EResourceType.USER_DETAILS_BY_USERNAME, { id: 'user1' })
.then((res) => {
console.log(res);
})
.catch((err) => {
console.log(err);
});
As demonstrated by the example, the raw data can be accessed by using the request
method of the FetcherService
class, which takes two parameters. The first parameter is the name of the requested resource, while the second is an object specifying the associated arguments required for the given resource. The complete list of resource type can be checked here. As for the resource specific argurments, they are the same as that of the methods of Rettiwt
class' methods for the respective resources, but structured as an object. Notice how the FetcherService
class takes the same arguments as the Rettiwt
class, and the arguments have the same effects as they have in case of Rettiwt
class.
Notes:
- For for hot-swapping in case of using
FetcherService
, the setters are accessed from the config
object as config.apiKey = ...
, config.proxyUrl = ...
, etc.
Data serialization
The data returned by all functions of Rettiwt
are complex objects, containing non-serialized fields like raw
. In order to get JSON-serializable data, all data objects returned by Rettiwt
provide a function toJSON()
which converts the data into a serializable JSON, whose type is described by their respective interfaces i.e, ITweet
for Tweet
, IUser
for User
and so on.
For handling and processing of data returned by the functions, it's always advisable to serialize them using the toJSON()
function.
Features
So far, the following operations are supported:
List

CLI Usage
Rettiwt-API provides an easy to use command-line interface which does not require any programming knowledge.
By default, the CLI operates in 'guest' authentication. If you want to use 'user' authentication:
- Generate an API_KEY as described in Authentication.
- Store the output API_KEY as an environment variable with the name 'API_KEY'.
- Additionally, store the API_KEY in a file for later use.
- Make sure to generate an API_KEY only once, and use it every time you need it.
- The CLI automatically reads this environment variable to authenticate against Twitter.
- Additionally, the API_KEY can also be passed in manually using the '-k' option as follows:
rettiwt -k <API_KEY> <command>
Help for the CLI can be obtained from the CLI itself:
- For help regarding the available commands, use the command
rettiwt help
- For help regarding a specific command, use the command
rettiwt help <command_name>

Additional information
- This API uses the cookies of a Twitter account to fetch data from Twitter and as such, there is always a chance (although a measly one) of getting the account banned by Twitter algorithm.
