Limitations

Global Search Not Supported

The Open5e API's global search endpoint (/v1/search/) returns HTML instead of JSON, so it is not supported by this node. Use the Search operation on individual resources instead.

Self-Hosted Instances Not Supported

The node only connects to the public Open5e API at api.open5e.com. Self-hosted Open5e instances are not supported in v1.

Advanced Filtering

Only the most commonly used filters are exposed in the node UI. For advanced filtering needs, use the HTTP Request node directly with the Open5e API.
