| ApiEditCheckReferenceUrlResponse | Response of action=editcheckreferenceurl: the verdict for the checked URL — "allowed" or "blocked". Always exactly one entry, keyed by the requested URL. |
| ApiLastModified | lastModified display parts of the edited page, as emitted by action=visualeditor/visualeditoredit and by DiscussionTools' discussiontoolsedit (both render the same last-modified widget data). |
| ApiVisualEditorCheckboxDef | One field of the edit form (checkboxesDef.wpMinoredit, wpWatchthis, wpWatchlistExpiry). |
| ApiVisualEditorEditResponse | Response of action=visualeditoredit. |
| ApiVisualEditorPageFrame | The page frame both visualeditor and visualeditoredit return. |
| ApiVisualEditorParseFragmentResponse | Response of action=visualeditor with paction=parsefragment: just the transformed fragment and the outcome flag. |
| ApiVisualEditorResponse | Response of action=visualeditor for paction=parse, wikitext and metadata, which share one payload. The other paction values return different shapes — see ApiVisualEditorTemplatesUsedResponse and ApiVisualEditorParseFragmentResponse. |
| ApiVisualEditorTemplatesUsedResponse | Response of action=visualeditor with paction=templatesused, where the module writes an HTML string instead of the usual object. |
