Example

How to call the Password Generator API in different programming languages.

cURL Request

curl -X GET \
  "https://api.apiverve.com/v1/passwordgenerator?count=10&length=12&complexity=strong&type=random&includeNumbers=true&includeSymbols=true&includeUppercase=true&includeLowercase=true&excludeSimilar=true&excludeAmbiguous=true&mixedCase=true&strict=true&wordCount=4&separator=-&capitalize=true&analyze=true" \
  -H "X-API-Key: your_api_key_here"

JavaScript (Fetch API)

const response = await fetch('https://api.apiverve.com/v1/passwordgenerator?count=10&length=12&complexity=strong&type=random&includeNumbers=true&includeSymbols=true&includeUppercase=true&includeLowercase=true&excludeSimilar=true&excludeAmbiguous=true&mixedCase=true&strict=true&wordCount=4&separator=-&capitalize=true&analyze=true', {
  method: 'GET',
  headers: {
    'X-API-Key': 'your_api_key_here',
    'Content-Type': 'application/json'
  }
});

const data = await response.json();
console.log(data);

Python (Requests)

import requests

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

response = requests.get('https://api.apiverve.com/v1/passwordgenerator?count=10&length=12&complexity=strong&type=random&includeNumbers=true&includeSymbols=true&includeUppercase=true&includeLowercase=true&excludeSimilar=true&excludeAmbiguous=true&mixedCase=true&strict=true&wordCount=4&separator=-&capitalize=true&analyze=true', headers=headers)

data = response.json()
print(data)

Go (net/http)

package main

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

)

func main() {
    req, _ := http.NewRequest("GET", "https://api.apiverve.com/v1/passwordgenerator?count=10&length=12&complexity=strong&type=random&includeNumbers=true&includeSymbols=true&includeUppercase=true&includeLowercase=true&excludeSimilar=true&excludeAmbiguous=true&mixedCase=true&strict=true&wordCount=4&separator=-&capitalize=true&analyze=true", nil)

    req.Header.Set("X-API-Key", "your_api_key_here")
    req.Header.Set("Content-Type", "application/json")

    client := &http.Client{}
    resp, err := client.Do(req)
    if err != nil {
        panic(err)
    }
    defer resp.Body.Close()

    body, _ := io.ReadAll(resp.Body)
    fmt.Println(string(body))

Response Structure

All API responses follow a consistent structure with the following fields:

Field	Type	Description	Example
`status`	string	Indicates whether the request was successful ("ok") or failed ("error")	`ok`
`error`	string \| null	Contains error message if status is "error", otherwise null	`null`
`data`	object \| null	Contains the API response data if successful, otherwise null	`{...}`

Learn more about response formats →

Response Data Fields

When the request is successful, the data object contains the following fields:

Response fields marked with Premium are available exclusively on paid plans.View pricing

Field	Type	Sample Value	Description
[ ] Array items:	array[10]	`Array of objects`	Array of generated password objects with details
└ `password`	string	`"aOwqDh0ZK*P;!M\|%oiFYJ!IK%TMXQO"`	The generated password string
└ `length`	number	`30`	Length of the generated password
└ `metadata`	object	`{...}`	Metadata about the password generation
└ `type`	string	`"random"`	Type of password generation method used
└ `complexity`Premium	string	`"strong"`	Complexity level of the password
└ `analysis`Premium	object	`null`	Strength analysis for the password. Returned only when analyze is true, and holds score, strength, feedback and entropy
`count`	number	`10`	Total count of passwords generated

Headers

Only X-API-Key is required. Optional headers include Accept for response format negotiation (JSON, XML, or YAML), User-Agent, and X-Request-ID for request tracing. See all request headers →

GraphQL AccessALPHA

Access Password Generator through GraphQL to combine it with other API calls in a single request. Query only the password generator data you need with precise field selection, and orchestrate complex data fetching workflows.

Test Password Generator in the GraphQL Explorer to confirm availability and experiment with queries.

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

GraphQL Endpoint

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

GraphQL Query Example

query {
  passwordgenerator(
    input: {
      count: 10
      length: 12
      complexity: "strong"
      type: "random"
      includeNumbers: true
      includeSymbols: true
      includeUppercase: true
      includeLowercase: true
      excludeSimilar: true
      excludeAmbiguous: true
      mixedCase: true
      strict: true
      wordCount: 4
      separator: "-"
      capitalize: true
      analyze: true
    }
  ) {
    passwords
    count
  }
}

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

CORS Support

The Password Generator API accepts cross-origin requests from any origin, so it can be called directly from browser-based applications without a proxy. See CORS support →

Rate Limiting

Password Generator requests are throttled per minute on the Free plan and unthrottled on paid plans. Exceeding the limit returns 429 Too Many Requests; rate-limit usage is reported in the X-RateLimit-Limit, X-RateLimit-Remaining, and X-RateLimit-Reset response headers. See per-plan limits and best practices →

Error Codes

The Password Generator API uses standard HTTP status codes — 200 on success, 400 for invalid parameters, 401 for missing or invalid keys, 403 for insufficient credits, 429 for rate-limit exhaustion, and 500/503 for server-side issues. Each error response includes an X-Request-ID header you can quote when contacting support. See full error handling guide →

SDKs for Password Generator

Official Password Generator packages on npm, PyPI, NuGet, and JitPack — plus a Postman collection and an OpenAPI spec. See the SDK guide →

JitPack

No-Code Integrations

Password Generator works with Zapier, Make, Pipedream, n8n, and Power Automate using the same API key. See setup guides →

Frequently Asked Questions

How do I get an API key for Password Generator?

Sign up for a free account at dashboard.apiverve.com. Your API key will be automatically generated and available in your dashboard. The same key works for Password Generator and all other APIVerve APIs. The free plan includes 1,000 credits plus a 500 credit bonus.

How many credits does Password Generator cost?

Each successful Password Generator API call consumes credits based on plan tier. Check the pricing section above for the exact credit cost. Failed requests and errors don't consume credits, so you only pay for successful password generator lookups.

Can I use Password Generator in production?

The free plan is for testing and development only. For production use of Password Generator, upgrade to a paid plan (Starter, Pro, or Mega) which includes commercial use rights, no attribution requirements, and guaranteed uptime SLAs. All paid plans are production-ready.
