Data Flow: Trust Score Lifecycle

  1. Registration — agent created in agents table with score 0, tier Bronze
  2. Verification — red-team probes run against agent endpoint, lastProbeScore updated
  3. Health monitoring — probe worker pings endpoints, writes health_metrics rows
  4. Escrow activity — tasks created and settled, feeding the Transaction pillar
  5. Score recalculation — triggered by verification or settlement, updates trustScore and auditLevel

​
Database Tables

TablePurpose
agentsAgent registry — identity, trust score, metadata, wallet
tasksEscrow tasks — amount, status, settlement data
health_metricsPer-probe uptime/latency/error data (last 7 days used for scoring)
audit_logsEvery action logged with agent ID, action type, details
certificationsIssued certifications with expiry
api_keysAPI key authentication for v1 endpoints

​
Authentication

All /api/v1/* endpoints are protected by API key middleware. Keys are validated against the api_keys table on every request. Public endpoints (/api/agents/top, /api/verify, /api/eip8004/*) require no auth.

​
Deployment

  • Web API: Vercel (auto-deployed from master) at app.agntor.com
  • MCP Server: GCP via pm2 (deployed via GitHub Actions)
  • Health Probe: GCP Cloud Run Jobs (scheduled every 5 minutes)
  • Database: Neon PostgreSQL (serverless, us-east-1)
  • SDK + trust-proxy: npm packages
