There was a problem hiding this comment.
I think I'm missing some context on this. Do we control both ends of the Spade conversation? I had imagined that Spade implemented a common API, but are the (Filecoin) storage providers supposed to run a Spade client specifically to fetch from our Spade service? Is that why we can extend it this way?
In that case, we could probably make the API know more about UCAN directly. Is the idea here not to do that to keep UCAN out of Spade? But HTTP headers are fair game because it's already dealing with HTTP URLs?

A proposal for how to do UCAN authorized retrieval in the Forge network with Spade.

Note: we could push this back further into the filecoin pipeline - i.e. the manifest it provides to Spade could include these headers...interested in opinions here.
