failed to marshal request body: %w

Error message

failed to marshal request body: %w

What it means

Returned by buildRequest when json.Marshal of the {query, max_results} map fails. With these plain value types this is effectively a defensive guard; it could only fire via invalid UTF-8 in the query or a future change to the payload type.
