Payment challenges on protected endpoints

• 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 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

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.
