Machine authentication

Secure. Simple machine authentication for your APIs and machines.

Issue, verify, and revoke API keys through one HTTP API—without building and operating an authentication system of your own.

Verify an API key in one request

RequestPOST /v1/verify-key

{
  "realm_id": "defaultrealm",
  "api_key": "ez_••••••••••"
}

Response200 OK

{
  "valid": true,
  "app": { "name": "payments" },
  "realm": { "name": "production" }
}

Simple by design

Three operations. One small authentication model.

Give every machine its own identity without turning authentication into another internal platform. Enzoguard keeps the lifecycle explicit from the first key to the millionth.

01
Issue
Create an app for a service, customer, agent, or workload. Issue a unique API key through the API and deliver the plaintext value once.
POST /v1/realms/{realm_id}/apps/{app_id}/api-keys
02
Verify
Send the key and realm to Enzoguard. A successful response gives your backend the verified app and realm identity it needs to authorize the request.
POST /v1/verify-key
03
Revoke
Delete one compromised or retired key. Enzoguard propagates the revocation globally in under one second, without rotating unrelated credentials.
DELETE /v1/realms/{realm_id}/apps/{app_id}/api-keys/{api_key_id}

Simple scales

Keep authentication out of your operational backlog.

A homegrown API-key system starts as a table and a hash. At scale, it also needs safe issuance, lookup, isolation, revocation, and a reliable verification path. Enzoguard packages that machinery behind a focused API and a small resource model.

Simple to secure

Less credential machinery to get wrong.

Security is easier to reason about when every credential has one purpose and a clear lifecycle.

One-time plaintext.The complete API key is returned only when it is created. Stored API-key resources never contain it.
Separate responsibilities.System keys manage configuration; customer API keys identify the machines using your product.
Targeted revocation.Revoke one key globally in under one second without redeploying or disrupting other identities.
