For AI Agents

ZAIGOOD's API is designed for autonomous agents that need to:

Verify entity status before executing transactions or signing contracts
Check compliance obligations for entities they manage
Monitor deadlines and trigger filings before penalties hit
Self-discover capabilities via the OpenAPI spec

Agent integration example

// In your agent's tool definition:
{
  "name": "zaigood_compliance_check",
  "description": "Check business entity compliance status",
  "parameters": {
    "name": "Entity legal name",
    "state": "2-letter US state code"
  },
  "endpoint": "POST https://zaigood.com/api/v1/compliance"
}
