Server tool list (5)

Raw names from tools/list. Only developers need these.

list_formatsList supported conversion formats. With no argument returns all input formats; with input_format returns the formats that input can be converted to.
list_optionsList the settings a given conversion accepts — resize, quality, codecs, bitrate, trim, crop and so on, with their exact names, types and allowed values. Call this before convert whenever the user asks for anything beyond a plain format change, and pass what it returns in the convert tool's options object.
create_uploadGet somewhere to put a local file — the right choice for ANY file that is not already at a URL, whatever its size. Say what the file should become in output_format: the conversion then starts on its own the instant the person sends the file, and collecting the result is all that is left. Returns an import_id plus two ways to deliver the bytes: a link to show the person so they upload from their own browser (use this when your own network cannot reach convert.online or storage), or a URL to PUT the bytes to yourself. Then call convert with the import_id to collect the result; it waits for the file to arrive.
convertConvert a file to another format and return a download link. Give it one of: source_url (any URL the server can fetch — the best option when the file is already somewhere reachable) or import_id (from create_upload — the way in for a file on someone's device or in your own sandbox, whatever its size). There is deliberately no way to pass the bytes inline: those calls are relayed and routinely never arrive, leaving the person watching a spinner. Settings such as resizing, quality or codecs go in options — call list_options first to get the exact names for the conversion. Runs against your account and counts toward your quota.
get_jobGet the status of a conversion job and its download link if finished.
