MurmurHash generates fast, non-cryptographic hashes using the MurmurHash3 algorithm. Ideal for hash tables, data partitioning, bloom filters, and checksums where cryptographic security isn't needed.

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

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

GraphQL AccessALPHA

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

Test MurmurHash 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 {
  murmurhash(
    input: {
      text: "hello world"
      seed: 0
      variant: "32"
    }
  ) {
    hash
    hashHex
    variant
    seed
  }
}

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

CORS Support

The MurmurHash API supports Cross-Origin Resource Sharing (CORS) with wildcard configuration, allowing you to call MurmurHash 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 MurmurHash directly from JavaScript running in the browser without encountering CORS errors. No proxy server or additional configuration needed.

Rate Limiting

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

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

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

Error Codes

The MurmurHash 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 MurmurHash?
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 MurmurHash and all other APIVerve APIs. The free plan includes 1,000 credits plus a 500 credit bonus.
How many credits does MurmurHash cost?

Each successful MurmurHash 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 murmurhash lookups.

Can I use MurmurHash in production?

The free plan is for testing and development only. For production use of MurmurHash, 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 MurmurHash from a browser?
Yes! The MurmurHash 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 MurmurHash credit limit?

When you reach your monthly credit limit, MurmurHash 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.
