Zero mana is a mana cost that can be paid without spending resources.
The action necessary for a player to pay such a cost (casting, activating, etc.) is the player's acknowledgment that they are paying it. Even though such a cost requires no resources, it's not automatically paid.
Zero mana was first used in Alpha on the Moxen as well as the Black Lotus. Zero mana appears predominantly on artifacts, which are due to the lack of a colored mana symbol: colorless. Kobolds and the Pact cycle are have a color indicator.
Keywords like affinity can reduce a cost to zero

From the Comprehensive Rules (July 25, 2025—Edge of Eternities)
- 118.5. Some costs are represented by {0}, or are reduced to {0}. The action necessary for a player to pay such a cost is the player’s acknowledgment that they are paying it. Even though such a cost requires no resources, it’s not automatically paid.
- 118.5a A spell whose mana cost is {0} must still be cast the same way as one with a cost greater than zero; it won’t cast itself automatically. The same is true for an activated ability whose cost is {0}.
