## Agent Registry String Format

The `agentRegistry` identifier follows this format:

```
{namespace}:{chainId}:{identityRegistryAddress}
```

Examples:
- Base: `eip155:8453:0x8004A169FB4a3325136EB29fA0ceB6D2e539a432`
- Base Sepolia: `eip155:84532:0x8004A818BFB912233c491871b3d84c89A494BD9e`
- ETH Sepolia: `eip155:11155111:0x8004a6090Cd10A7288092483047B097295Fb8847`
- Polygon Amoy: `eip155:80002:0x8004ad19E14B9e0654f73353e8a0B600D46C2898`

For production use, use a provider like Alchemy or Infura with your own API key.

## Agent0 SDK Default Subgraph URLs

The Agent0 SDK auto-configures subgraph endpoints per chain for indexed queries (search, feedback aggregation). No manual configuration needed when using the SDK.

## 8004scan Explorer

View any registered agent at: `https://www.8004scan.io/`

After registration, agents are browsable by agentId and chain.
