Base URL: https://app.sonjj.com

Introduction

Welcome to SonjjAPI!

This powerful API provides a variety of functions to enhance your application and streamline your workflow. Whether you're looking to:

  • Verify emails — validate deliverability and detect disposable addresses
  • Create temporary emails — Gmail, Outlook, and generic temp mail inboxes
  • Check SEO metrics — Moz, Ahrefs, backlink analysis, Google index status
  • Generate data — user profiles, phone validation, HTML-to-Markdown conversion

SonjjAPI has you covered.

Getting Started

  1. Sign up at my.sonjj.com to create your account
  2. Get your API key from the API section of your dashboard
  3. Purchase credits — see Pricing
  4. Make your first request — include your API key in the X-Api-Key header

SDKs & Tools

You can use SonjjAPI with any HTTP client:

  • cURL — quick testing from the command line
  • Python — requests or httpx
  • JavaScript / Node.js — fetch or axios
  • Postman / Insomnia — import the OpenAPI schema directly

Support

Authentication

Authentication

All API requests require authentication via an API key passed in the request header.

Getting Your API Key

  1. Log in at my.sonjj.com
  2. Navigate to the API section
  3. Copy your X-Api-Key

Using Your API Key

Include the key in every request header:

X-Api-Key: your_api_key_here

Example Requests

cURL

curl -X GET "https://app.sonjj.com/v1/check_email/validate?email=test@example.com" \
  -H "X-Api-Key: your_api_key_here"

Python

import requests

response = requests.get(
"https://app.sonjj.com/v1/check_email/validate",
params={"email": "test@example.com"},
headers={"X-Api-Key": "your_api_key_here"}
)
print(response.json())

JavaScript

const response = await fetch(
  "https://app.sonjj.com/v1/check_email/validate?email=test@example.com",
  { headers: { "X-Api-Key": "your_api_key_here" } }
);
const data = await response.json();

Error Responses

Status Meaning
401 Missing or invalid API key
403 API key valid but access denied (insufficient credits or plan)
Rate Limits

Rate Limits

SonjjAPI enforces rate limits to ensure fair usage and service stability across all users.

How It Works

Rate limiting is applied per API key and tracked at two levels:

Level Limit
Per minute Depends on your plan
Per day Depends on your plan

When you exceed the rate limit, the API returns HTTP 429 with a Retry-After header (seconds to wait) and body:

{
  "error": {
"code": 429,
"message": "Rate limit exceeded. Please wait before retrying."
  }
}

Best Practices

  • Cache responses on your side when possible
  • Implement exponential backoff on 429 responses
  • Use bulk endpoints where available instead of looping single calls
  • Monitor your credit and request usage at my.sonjj.com
Error Codes

Error Codes

SonjjAPI uses standard HTTP status codes and returns errors in a consistent JSON format.

Error Response Format

{
  "error": {
"code": 400,
"message": "Human-readable description of the error"
  }
}

HTTP Status Codes

Code Name Description
200 OK Request successful
400 Bad Request Invalid parameters or missing required fields
401 Unauthorized Missing or invalid X-Api-Key header
402 Payment Required Insufficient credits to complete the request
403 Forbidden Access denied — plan does not include this endpoint
404 Not Found The requested resource does not exist
422 Unprocessable Entity Request body is valid JSON but fails business validation
429 Too Many Requests Rate limit exceeded — slow down and retry
500 Internal Server Error Something went wrong on our end
503 Service Unavailable Server is temporarily overloaded or under maintenance

Handling Errors

Python example

import requests

response = requests.get(
"https://app.sonjj.com/v1/check_email/validate",
params={"email": "test@example.com"},
headers={"X-Api-Key": "your_api_key_here"}
)

if response.status_code == 200:
data = response.json()
elif response.status_code == 429:
print("Rate limited — implement backoff")
elif response.status_code == 402:
print("Insufficient credits")
else:
error = response.json().get("error", {})
print(f"Error {error.get('code')}: {error.get('message')}")
