Table of Contents

The DEXTools API provides easy access to a wealth of data on decentralized finance (DeFi) tokens, pairs, blockchains, and more. This in-depth guide will walk through everything you need to know to start using the DEXTools API as a complete beginner.


Introduction to APIs

Let’s first cover the basics of what an API actually is.

API stands for Application Programming Interface. It provides a way for two software programs to communicate with each other and share data. APIs work by exposing certain functions and data points that another application can then access.

For example, the DEXTools API exposes endpoints and data from DEXTools’ databases that you can access for your own applications. The API endpoints are like different URLs you can query to get specific pieces of data back.


Overview of the DEXTools API

The DEXTools API taps into DEXTools‘ extensive databases of metrics across dozens of blockchains. It can be used to build trading bots, analytics platforms, portfolio trackers, and more. This API service can be a goldmine for developers, traders, and enthusiasts looking to gain insights into various cryptocurrencies and their trading activities

Let’s dive into the key features that the DEXTools’ API provides access to:


Pair Information

Using the DEXTools API, you can retrieve detailed information about trading pairs. This information includes the pair’s ID, chain details, exchange information, token details, creation block, symbol, name, type, and more.

Additionally, you can access metrics such as reserves, liquidity, and DEXTools’ proprietary DextScore, which gives insights into a pair’s overall reliability.


Token Insights

The DEXTools API allows you to gather in-depth information about specific tokens. This includes the token’s ID, chain details, symbol, name, creation block, market metrics like fully diluted valuation (fdv), total market capitalization (tmcap), holders, transaction count, circulating supply, maximum supply, total supply, price, decimals, and audit information.

The audit information covers code verification, transaction locking, minting, proxy usage, and more.


Blockchain and Exchange Details

You can use the DEXTools API to fetch a list of available

blockchains and their associated exchanges. This feature provides an overview of the blockchain ecosystem and the exchanges that facilitate trading within it.

And much more.


Understanding the Documentation

The DEXTools API documentation lives at

It outlines all the available endpoints, request parameters, and response schemas. Spend some time browsing the docs to get an idea of what data you can access.

Pay attention to:

    • The endpoint URLs: these indicate the API resource you are accessing like /pairs or /tokens.
    • The HTTP method: GET – determines the type of request.
    • The parameters: these are options that filter or shape the response.
    • The response structure: this shows the JSON data that will be returned.


    Making Your First API Call

    Let’s try getting some data on a crypto pair. We will use cURL, a common command line tool for APIs.

    Run this command in your terminal, replacing YOUR_API_KEY:

    This makes a GET request to the pair endpoint, gets 1 day interval data for UNI-ETH, and passes your API key. You will see a JSON response containing all the pair data.

    This data can now be used in your own application!

    A Basic Example: Retrieving Pair Information

    To illustrate how to use the DEXTools API, let’s walk through a basic example of retrieving pair information. We’ll use a hypothetical scenario where you’re interested in fetching details about a specific trading pair.

      • Obtain an API Key: first, request an API key from DEXTools by filling out the provided form.
      • Construct the API Request: using your preferred programming language, construct an HTTP request to the appropriate endpoint. For instance, to get pair information, you would make a GET request to /v1/pair/{pair_id}.
      • Include the API Key: remember to include your API key as a header or parameter in the request. This key authenticates your access to the API.
      • Receive and parse the response: once you send the request, you’ll receive a response in JSON format. Parse this response to extract the pair information, such as ID, chain, exchange, token details, metrics, and DextScore.



      The DEXTools’ API puts their robust, multi-chain DeFi data at your fingertips. Integrating this data into your own application unlocks powerful new opportunities for analytics, trading, and market insights. Whether you’re a developer seeking data for analysis, a trader looking to make informed decisions, or a curious enthusiast exploring the depths of the cryptocurrency realm, the DEXTools API is a valuable tool at your disposal.

      Hopefully this guide provided a helpful introduction to the API. Let us know if you have any other questions!
