# authenticate

Call this to start or confirm 1inch Business login. HTTP 401 means you are still anonymous (initialize 200 is not login). After OAuth, call again until the result is authenticated: true with organizationId. Then use swap, orderbook, product_api, or debug. Do not treat a PaymentRequired / x402 result as login.

## Recommended policy (PolicyLayer)

Verdict: **Rate-limited**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches 1inch MCP:

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "authenticate": {
      "limits": [
        {
          "counter": "authenticate_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
  }
