# Registry

> Query all registered agents from the on-chain Solana registry

The registry endpoint provides a convenient HTTP interface to the on-chain SPL Memo registry. It reads the Solana blockchain and returns all registered agents.

## Endpoint

```
GET /registry
```

**Authentication:** None — this endpoint is publicly accessible.

## Response

```json theme={null}
{
  "network": "devnet",
  "registry_address": "DeKbktsRhJ4sWH344Fxzy52HoC4und9Vk4pcHUTvcWw5",
  "agents": [
    {
      "name": "data",
      "manifest_url": "https://merchant.example.com/.well-known/agent.json",
      "wallet": "5Yz3k...XqP",
      "signature": "3rQm...abc",
      "timestamp": 1711820400
    }
  ],
  "total": 1,
  "fetched_at": "2026-03-30T19:00:00Z"
}
```

## Response Fields

<ResponseField name="network" type="string">
  The Solana cluster scanned (devnet, mainnet-beta).
</ResponseField>

<ResponseField name="registry_address" type="string">
  The public key of the registry coordination wallet.
</ResponseField>

<ResponseField name="agents" type="array">
  <Expandable title="Each agent object contains:">
    <ResponseField name="name" type="string">Agent name from the SPL Memo</ResponseField>
    <ResponseField name="manifest_url" type="string">URL to the agent's service manifest</ResponseField>
    <ResponseField name="wallet" type="string">The registering wallet's public key</ResponseField>
    <ResponseField name="signature" type="string">The registration transaction signature</ResponseField>
    <ResponseField name="timestamp" type="number">Unix timestamp of the registration</ResponseField>
  </Expandable>
</ResponseField>

## How It Works

Under the hood, this endpoint:

1. Calls `getSignaturesForAddress` on the known registry wallet
2. Fetches each transaction's memo data
3. Parses memos that match the format `{"agent":"...","manifest":"...","v":1}`
4. Returns all valid registrations

<Tip>
  This is the same data returned by the `discover_registry` MCP tool. The HTTP endpoint is provided for non-MCP clients (browsers, curl, monitoring tools, etc.).
