Input

Field	Type	Default	Description
`queries`	string	`aspirin,caffeine,2244`	Comma-, semicolon-, or newline-separated compound names or numeric CIDs
`queryType`	enum	`auto`	`auto` (detect CID vs name), `name`, or `cid`
`maxItems`	integer	10	Max results (1–100)
`includeSynonyms`	boolean	true	Fetch and include compound synonyms

Output

Each record includes:

Field	Description
