41 vendors, each mapped to the Hanzo capability that answers it — how to start, nouns, the call before and after, and what does not carry.
41 guides, one per vendor. Each one starts with the shortest path to a working
call, names the capability that answers the vendor, maps their nouns onto ours,
shows the same call both ways, and says plainly what you lose.
Every capability lives at one address — /v1/<name> — and the operation counts

Every call below authenticates with one header:
-H " Authorization: Bearer $HANZO_API_KEY " A secret key (sk-) resolves to a user; a publishable key (pk-) resolves to an
org. There is no org, user or project header to set — the gateway derives all
three from the validated key. Whatever your old vendor did with an account SID, a
workspace id, an entity or a project slug, here it is the key.
See API keys for how to mint one, and Errors
for the shape every failure takes.
