Quickstart

Make your first Cludo API call within a few minutes.

This guide walks you through making your first search API call using the v4 API.

Prerequisites: You need a Cludo account with at least one engine configured. Sign in to MyCludo to get your credentials.

Step 1: Find your region

Your region is determined by your customer ID:

Customer ID	Region	Base URL
Below 10,000,000	EU	https://api.cludo.com
10,000,000+	US	https://api-us1.cludo.com

Step 2: Get your credentials

Log in to MyCludo API settings and find the following values:

Value	Where to find it
Customer ID	Dashboard → Account Settings
Engine ID	Dashboard → Engines → select your engine
API Key	MyCludo API settings

Step 3: Build your auth token

Unless an endpoint says otherwise, use Basic (API Key) authentication for Cludo API requests:

# Format: base64(customerId:apiKey)
echo -n "3:c8fk2L9mK4pQ" | base64
# Output: MzpjOGZrMkw5bUs0cFE=

SiteKey authentication is available for public-facing search where you do not want to expose your API key. See the Authentication guide for SiteKey token format.

Try it: build your token

Use the tool below to generate a Basic or SiteKey authorization header and a ready-to-run cURL command. Basic authentication is the default choice unless you are building a public client-side search integration.

Step 4: Make your first search

Keep Basic API keys private. Use the Basic examples from a trusted backend, script, or local test. For browser code, use SiteKey authentication instead.

cURL Basic (EU)

curl -X POST "https://api.cludo.com/api/v4/3/6/search" \
  -H "Authorization: Basic MzpjOGZrMkw5bUs0cFE=" \
  -H "Content-Type: application/json" \
  -d '{
    "query": "*",
    "page": 1,
    "perPage": 10
  }'

Step 5: Understand the response
