One request shape covers every network.
Each network sets its own caption limit, media rules and auth. These pages document all of it — the same numbers the API's pre-flight enforces, from the same table.
11 networks supported, 5 publishing for anyone today, the rest clearing review — the status page names each one.
Short, fast and unforgiving of padding.
