# FunnelKit Shortener

> FunnelKit Shortener is an agent-native URL shortener with no surprise bills. Create, edit and track short links on link-staging.funnelkit.com or your own domain through a REST API (https://linkapp-staging.funnelkit.com/api), the `fks` CLI, or a remote MCP server (https://linkapp-staging.funnelkit.com/mcp). Limits are soft: redirects never stop and there are no overage charges. The service is in invite-only private beta.

Authenticate every API, CLI and MCP request with a workspace API key: `Authorization: Bearer fks_...`. Errors are JSON: `{"error":{"code":"...","message":"...","details":...}}`. The OpenAPI 3.1 spec is at https://linkapp-staging.funnelkit.com/api/openapi.json.
