One package, a few lines of config, and every call is checked and logged.

The five libraries share one contract, so a team with services in two languages gets the same behavior from both:

• Authorize inbound calls against your grants before your handler runs, with a short in-process cache (300 seconds by default, 0 to turn it off).
• Report every request and response, with masking rules applied before the payload leaves your process.
• Capture unhandled errors with a normalized stack trace, so the same fault groups as one issue.
• Declare endpoint versions, so EndPointBlank can show who still calls a deprecated one.
• Authorize your outbound calls to other EndPointBlank-protected services with short-lived tokens, so your own secret is never sent to them.

Every library reads the same variables, so the same deployment config works whichever language a service is written in:

ENDPOINTBLANK_CLIENT_ID=your-client-id
ENDPOINTBLANK_CLIENT_SECRET=your-client-secret
ENDPOINTBLANK_APP_NAME=orders-service
ENDPOINTBLANK_ENV=production
