Authentication

All API requests must include an x-token header with your API token (minimum 10 characters).

x-token: YOUR_TOKEN

Note

Don’t have a token yet? Generate one for free on the Token Management page.

Example

cURL

curl 'https://api.echovalue.dev/kv/default/mykey' \
  -H 'x-token: mytoken'

JavaScript

fetch('https://api.echovalue.dev/kv/default/mykey', {
  headers: {
    'x-token': 'mytoken'
  }
});

Python

import requests

requests.get('https://api.echovalue.dev/kv/default/mykey',
  headers={'x-token': 'mytoken'}
)

PHP

<?php
$ch = curl_init('https://api.echovalue.dev/kv/default/mykey');
curl_setopt($ch, CURLOPT_HTTPHEADER, ['x-token: mytoken']);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$response = curl_exec($ch);
curl_close($ch);
?>

Go

package main

import "net/http"

func main() {
    req, _ := http.NewRequest("GET", "https://api.echovalue.dev/kv/default/mykey", nil)
    req.Header.Set("x-token", "mytoken")

    client := &http.Client{}
    client.Do(req)
}

Response Headers

Paid endpoints return x-cost and x-balance headers. See Response Headers for details and language examples.
