What you get

Scoped API keys

Test and live keys with granular scopes. Revoke a key without rotating unrelated integrations.

Usage visibility

Metered calls and spend signals in the dashboard so teams can reconcile usage with budgets.

Stable API surface

Versioned routes under /v1, consistent error objects, and examples aligned with the docs.

Quick start

Sign in to the dashboard and create a test API key.
Read the documentation for authentication, scopes, and error codes.

Example agent call (replace the key and body with values from your project):

curl -X POST https://api.hardalion.com/v1/agents/execute \
  -H "Authorization: Bearer hdl_test_..." \
  -H "Content-Type: application/json" \
  -d '{"agent":{"model":"<your-model>","system_prompt":"You are helpful.","tools":[]},"prompt":"Hello"}'
