Indonesian embassy officials met Siti Aisyah, 25, on Saturday in the Malaysian capital.
She said she was given the cash to smear Kim Jong-nam's face with "baby oil" as part of a reality show joke.
Tests show Mr Kim was killed with the highly toxic nerve agent VX.
It is classified as a weapon of mass destruction by the United Nations.
Mr Kim died last week after two women accosted him briefly in a check-in hall at a Kuala Lumpur airport.
