Cross-platform identity API — the same person, 11 handles
Resolve a handle you already have on each platform, and read the links a person publishes about themselves. We do not guess that two handles are the same human.
The problem
A creator is one person and 11 accounts, and the only evidence that links them is what they publish themselves — a bio, a link page, a verified field. Inferring identity from name similarity invents a claim nobody made.
What answers it — 11 endpoints

Shape, parameters and the errors each one returns are in the endpoint reference, generated from the same catalogue the router reads.
The recipe
There is no recipe for this one yet. The 3 that exist are all about the archive, and pointing you at one of them from here would send you to steps that do not answer this question. The recipe index says which they are.
