DEXUtils Pro API Authentication: API Keys & Quick Code Examples

Every request to the DEXUtils Pro API must include your API key. The API uses standard token authentication — you pass your key in the request header, and the server validates it before processing the request. There are no cookies, sessions, or OAuth flows to manage.

How Authentication Works

Include the following header in every API request:

API-KEY: YOUR_API_KEY

Replace YOUR_API_KEY with the key you generate from your DEXUtils platform. The header is required on all endpoints — there are no public Pro API routes.

Get Your API Key (TBD)

Go to Platform and sign in to your account.

Open API Keys settings

Click your avatar in the top-right corner, then navigate to Settings → API Keys.

Generate a new key

Click Generate New Key, give the key a descriptive label (for example, production-bot or analytics-dashboard), and confirm.

Copy and store the key securely

Your key is displayed once. Copy it immediately and store it in a secrets manager or environment variable. You cannot retrieve the full key again after closing the dialog.

Code Examples

The examples below authenticate against the GET /news endpoint, which retrieves the latest cryptocurrency news.

curl https://api.dexutils.io/news \
  -H "API-KEY: YOUR_API_KEY" \
  -H "Content-Type: application/json"

import requests

headers = {
    "API-KEY": "YOUR_API_KEY",
    "Content-Type": "application/json"
}

response = requests.get("https://api.dexutils.io/news", headers=headers)
print(response.json())

const response = await fetch('https://api.dexutils.io/news', {
  headers: {
    'API-KEY': 'YOUR_API_KEY',
    'Content-Type': 'application/json'
  }
});
const data = await response.json();
console.log(data);

package main

import (
    "fmt"
    "io"
    "net/http"
)

func main() {
    req, _ := http.NewRequest("GET", "https://api.dexutils.io/news", nil)
    req.Header.Set("API-KEY", "YOUR_API_KEY")
    req.Header.Set("Content-Type", "application/json")

    client := &http.Client{}
    resp, _ := client.Do(req)
    defer resp.Body.Close()
    body, _ := io.ReadAll(resp.Body)
    fmt.Println(string(body))
}

Authentication Errors

If the API rejects your request due to an authentication problem, you’ll receive one of the following HTTP error responses:

Status Code	Meaning
`401 Unauthorized`	Missing or malformed `API-KEY` header
`403 Forbidden`	Header format is valid but key is rejected
`429 Too Many Requests`	Rate limit exceeded

Each error response includes a JSON body with a error field. See the Error Codes reference for the full list of error shapes and recommended handling strategies.
