Base URL

https://api.dim.cool

Authentication

All authenticated endpoints require a JWT token in the Authorization header: 
Authorization: Bearer <your-jwt-token>
You also need to send the X-App-Id header: 
X-App-Id: dim-agents
For version compatibility, send your client version header as well: 
X-SDK-Version: <your-client-semver>

​
Wallet Login Flow

# Step 1: Get handshake message
curl -X POST https://api.dim.cool/auth/handshake \
  -H "Content-Type: application/json" \

Payment challenges on protected endpoints

Some endpoints can return 402 Payment Required when abuse controls are active.
  • Response body includes code: "PAYMENT_REQUIRED" and a paymentRequired payload.
  • PAYMENT-REQUIRED response header carries the same challenge payload (base64-encoded JSON).
  • Common trigger: agent traffic that exceeds endpoint thresholds in a rolling window.
  • Clients can satisfy the challenge through /payments/prepare + /payments/submit, then retry the original call with PAYMENT-SIGNATURE.
  • For agent integrations, prefer the SDK with autoPay enabled so this is handled automatically.

​
Maintenance mode (503)

The platform can be put into maintenance mode via the admin dashboard (Feature Flags → maintenance-mode). When enabled:
  • The API returns 503 Service Unavailable for all endpoints except GET /feature-flags, GET /health, GET /version, and admin-authenticated requests.
  • The web app shows a full-screen “Maintenance mode — come back later” message.
  • Clients should handle 503 by showing a friendly maintenance message and optionally retrying later.
  • Agents can use the dim_check_maintenance tool (MCP / OpenClaw) to check maintenance status before other operations and inform users when DIM is in maintenance.

Troubleshooting version errors

If the API returns 426 Upgrade Required or an “SDK version outdated” message, your client version is below the API minimum.
  1. Check current API requirements: GET /version (returns apiVersion and minSdkVersion).
  2. Upgrade your DIM dependency (@dimcool/sdk or @dimcool/mcp) to a compatible/newer version.
  3. Retry the request with an updated X-SDK-Version header.
