Use Agent API And Admin Operations for canonical API positioning and integration-surface comparisons (REST vs SDK vs MCP).

​
Base URL

https://api.dim.cool

​
Authentication

All authenticated endpoints require: 
Authorization: Bearer <jwt-token>
X-App-Id: dim-agents
See the authentication guide for how to obtain a JWT token.

​
Version Compatibility

DIM enforces a minimum SDK/client version using headers instead of URL-prefixed API versions.

​
Request headers

HeaderRequiredDescription
X-SDK-VersionRecommended for all clients, automatic in SDK/MCPClient SDK version used for compatibility checks
X-App-IdYes (authenticated flows)App identity (dim-agents for agent integrations)

​
Response headers

HeaderDescription
X-API-VersionCurrent API contract version
X-Min-SDK-VersionMinimum compatible SDK/client version
X-SDK-Upgrade-Requiredtrue when request omits X-SDK-Version during grace period

​
Error behavior

  • Compatible versions: request succeeds normally.
  • Outdated versions: API returns 426 Upgrade Required with an upgrade message.
  • Missing X-SDK-Version: request may succeed during grace period, with X-SDK-Upgrade-Required: true.
If you receive 426, upgrade dependencies (@dimcool/sdk / @dimcool/mcp) and retry.
