Quickstart
Make your first request.
Create a workspace, issue a key and retrieve live Marked data in a few minutes.
Issue an API key
Create a key in the dashboard and copy it immediately. Marked stores only its hash, so a lost key must be replaced.
Call the API
Send the key in X-API-Key. A bearer token is also accepted.
Authentication
Keys begin with mk_live_ and belong to a workspace. Keep them server-side and out of source control, browser bundles and logs.
One authenticated REST data call or one MCP tools/call invocation counts as one request. Initialization, capability discovery and tools/list are not billed. Developer: 60/minute and 2 concurrent; Builder: 300/minute and 10; Scale: 1,200/minute and 25.
