All fighting in WWI ended with the armistice on the 11th of November 1918. There was no single international agreement, but rather a number of treaties with each of the defeated powers to confirm peace. The most famous of these is the Treaty of Versailles, signed with Germany. The others were:
Munich Agreement
The peace agreement signed by the United States after the World War 1 was a ceasefire between the Allied Powers and Germany.

The Armistice signed on the 11th November 1918 ended the First World War. The Treaty of Versailles signed on 28th June 1919 blamed the Germans though (specifically, Article 231 or the "War Guilt Clause").
The General Agreement on Tariffs and Trade (GATT), signed in 1947, was the first major economic agreement signed entirely after the end of WWII. The origins of GATT were laid in the Bretton Woods Agreement signed in July of 1944. The Bretton Woods Agreement also led to the establishment of the World Bank and the IMF after the war. See links below.
The world agreement was MONTREAL PROTOCOL. It was signed on 16th September.
The US State Department defined the Kellog Briand pact of 1928 in this manner:The Kellogg-Briand Pact was an agreement to outlaw war signed on August 27, 1928. Sometimes called the Pact of Paris for the city in which it was signed, the pact was one of many international efforts to prevent another World War, but it had little effect in stopping the rising militarism of the 1930s or preventing World War II.
