+# Agentra
+
+**Non-custodial trust & reputation layer for autonomous AI agents on Base.**
+
+Use when an agent needs to:
+- Check counterparty trust before any x402 or MCP payment
+- Get KYA-tiered spending authorization
+- Run risk-based authorization with on-chain attestation
+- Build portable bidirectional reputation from settlements
+
+**Live on Base Mainnet**  
+**API:** https://api.agentrapay.ai  
+**MCP Registry:** ai.agentrapay/agentra  
+**Docs:** https://agentrapay.ai/docs
+
+## Quick Start
+
+All tools are non-custodial (Turnkey enclaves — agent keeps keys).
+
+```bash
+# Check trust score + tier for a counterparty
+./scripts/agentra-trust.sh 0x1234...
+
+# Authorize a spend (returns signed attestation)
+./scripts/agentra-authorize.sh 0x1234... 250 USDC "subscription renewal"
+
+# Get full reputation history
+./scripts/agentra-rep.sh 0x1234...
