Body

application/json
​
script
string
required

JavaScript expression to evaluate in the device's foreground Chrome tab (CDP Runtime.evaluate). It is an expression, not a function body — the expression's value is returned (no top-level 'return'). Must evaluate to a JSON-serializable value; wrap multi-statement logic in an IIFE, e.g. (() => { ... ; return x })().

Response

OK

​
result
any
required

JSON-serialized return value of the script (null if it returned undefined). Non-JSON-serializable numbers (Infinity, NaN, -0) are returned as their string representation.
