# Put a resource in a service

`POST https://evohub.io/api/v1/catalog/resources/{id}/component`

Part of the [Catalog API](https://docs.evohub.io/catalog.md) reference · operationId `bindResource`.

Binds the resource to a service by hand (`{"component": "<id or
slug>"}`), or unbinds it (`{"component": null}`). The key is
required. A binding made here is never undone by a sweep. Unbinding a
resource whose `evohub.io/component` annotation names a service lasts
only until its next sweep: change the manifest to move it for good.

Requires the `catalog:resource:write` scope.
