Here are examples of how to call the Levenshtein Distance API in different programming languages:

curl -X POST \
  "https://api.apiverve.com/v1/levenshteindistance" \
  -H "X-API-Key: your_api_key_here"

const response = await fetch('https://api.apiverve.com/v1/levenshteindistance', {

  headers: {
    'X-API-Key': 'your_api_key_here',
    'Content-Type': 'application/json'
  }
});

console.log(data);

import requests

headers = {
    'X-API-Key': 'your_api_key_here',
    'Content-Type': 'application/json'
}

response = requests.post('https://api.apiverve.com/v1/levenshteindistance', headers=headers)

data = response.json()
print(data)

const https = require('https');

const options = {
  method: 'POST',
  headers: {
    'X-API-Key': 'your_api_key_here',

};

const req = https.request('https://api.apiverve.com/v1/levenshteindistance', options, (res) => {
  let data = '';
  res.on('data', (chunk) => data += chunk);
  res.on('end', () => console.log(JSON.parse(data)));
});

req.end();

Authentication

The Levenshtein Distance API requires authentication via API key. Include your API key in the request header:

X-API-Key: your_api_key_here

Response

The Levenshtein Distance API returns responses in JSON, XML, YAML, and CSV formats:

Example Responses

{
  "status": "ok",
  "error": null,
  "data": {
    "distance": 3,
    "similarity": 57.14,
    "matchLevel": "medium",
    "string1Length": 6,
    "string2Length": 7,
    "string1": "kitten",

GraphQL AccessALPHA

Access Levenshtein Distance through GraphQL to combine it with other API calls in a single request. Query only the levenshtein distance data you need with precise field selection, and orchestrate complex data fetching workflows.

Credit Cost: Each API called in your GraphQL query consumes its standard credit cost.

POST https://api.apiverve.com/v1/graphql

query {
  levenshteindistance {
    distance
    similarity
    matchLevel
    string1Length
    string2Length
    string1
    string2
  }
}

Note: Authentication is handled via the x-api-key header in your GraphQL request, not as a query parameter.

CORS Support

The Levenshtein Distance API supports Cross-Origin Resource Sharing (CORS) with wildcard configuration, allowing you to call Levenshtein Distance directly from browser-based applications without proxy servers.

Browser Usage: You can call Levenshtein Distance directly from JavaScript running in the browser without encountering CORS errors. No proxy server or additional configuration needed.

Rate Limiting

Levenshtein Distance API requests are subject to rate limiting based on your subscription plan. These limits ensure fair usage and maintain service quality for all Levenshtein Distance users.

Learn more about rate limiting →

Rate Limit Headers

When rate limits apply, each Levenshtein Distance response includes headers to help you track your usage:

Handling Rate Limits

Free Plan: When you exceed your rate limit, Levenshtein Distance returns a 429 Too Many Requests status code. Your application should implement appropriate backoff logic to handle this gracefully.

Paid Plans: No rate limiting or throttling applied. All paid plans (Starter, Pro, Mega) are production-ready.

Best Practices for Levenshtein Distance:

• Monitor the rate limit headers to track your Levenshtein Distance usage (Free plan only)
• Cache levenshtein distance responses where appropriate to reduce API calls
• Upgrade to Pro or Mega for guaranteed no-throttle Levenshtein Distance performance

Note: Levenshtein Distance rate limits are separate from credit consumption. You may have credits remaining but still hit rate limits when using Levenshtein Distance on Free tier.

Error Codes

The Levenshtein Distance API uses standard HTTP status codes to indicate success or failure:
