Quickstart

Make your first request.

Create a workspace, issue a key and retrieve live Marked data in a few minutes.

Create an account

Sign in, choose Developer, Builder or Scale, and complete checkout.

Get started ↗

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.

API calls and MCP tool calls use the same monthly request allowance.
