Hash Generator is a tool for generating cryptographic hashes from text. It supports multiple algorithms including MD5, SHA-1, SHA-256, SHA-384, SHA-512, and BLAKE2 variants for data integrity and security applications.

The Hash Generator API provides reliable and fast access to hash generator data through a simple REST interface. Built for developers who need consistent, high-quality results with minimal setup time.

To use Hash Generator, you need an API key. You can get one by creating a free account and visiting your dashboard.

GraphQL AccessALPHA

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

Test Hash 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 {
  hashgenerator(
    input: {
      text: "Hello World"
      algorithms: "sha256,md5"
    }
  ) {
    input_text
    input_length
    algorithms_used
    hashes {
      sha256
      md5
    }
    hash_details
  }
}

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

CORS Support

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

CORS HeaderValueDescription
Access-Control-Allow-Origin*Accepts requests from any origin
Access-Control-Allow-Methods*Accepts any HTTP method
Access-Control-Allow-Headers*Accepts any request headers

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

Rate Limiting

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

PlanRate LimitDescription
Free5 requests/minHard rate limit enforced - exceeding will return 429 errors
StarterNo LimitProduction ready - standard traffic priority
ProNo LimitProduction ready - preferred traffic priority
MegaNo LimitProduction ready - highest traffic priority

Learn more about rate limiting →

Rate Limit Headers

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

HeaderDescription
X-RateLimit-LimitMaximum number of requests allowed per time window
X-RateLimit-RemainingNumber of requests remaining in the current window
X-RateLimit-ResetUnix timestamp when the rate limit window resets

Handling Rate Limits

Free Plan: When you exceed your rate limit, Hash Generator 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 Hash Generator:

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

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

Error Codes

The Hash Generator API uses standard HTTP status codes to indicate success or failure:

CodeMessageDescriptionSolution
200OKRequest successful, data returnedNo action needed - request was successful
400Bad RequestInvalid request parameters or malformed requestCheck required parameters and ensure values match expected formats
401UnauthorizedMissing or invalid API keyInclude x-api-key header with valid API key from dashboard
403ForbiddenAPI key lacks permission or insufficient creditsCheck credit balance in dashboard or upgrade plan
429Too Many RequestsRate limit exceeded (Free: 5 req/min)Implement request throttling or upgrade to paid plan
500Internal Server ErrorServer error occurredRetry request after a few seconds, contact support if persists
503Service UnavailableAPI temporarily unavailableWait and retry, check status page for maintenance updates

Frequently Asked Questions

How do I get an API key for Hash 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 Hash Generator and all other APIVerve APIs. The free plan includes 1,000 credits plus a 500 credit bonus.
How many credits does Hash Generator cost?

Each successful Hash 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 hash generator lookups.

Can I use Hash Generator in production?

The free plan is for testing and development only. For production use of Hash 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.

Can I use Hash Generator from a browser?
Yes! The Hash Generator API supports CORS with wildcard configuration, so you can call it directly from browser-based JavaScript without needing a proxy server. See the CORS section above for details.
What happens if I exceed my Hash Generator credit limit?

When you reach your monthly credit limit, Hash Generator API requests will return an error until you upgrade your plan or wait for the next billing cycle. You'll receive notifications at 80% and 95% usage to give you time to upgrade if needed.
