Here players can search for attributes/genes that they might need for a breeding project, like a Tribute Cutie, or a special elemental Cutie (many refer to them as Pure Breds). A Cutie can be listed for siring, but opposite from the regular marketplace, the Cutie is not sold itself. The listed Cutie can be bred for a fee. \ This means that any other player that is interested in the genes of another player's Cutie that is listed on the market can pay a fee to breed with that Cutie and get the resulting offspring. This method allows players to expand the gene pool of their army with a bit more precision. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.blockchaincuties.com/blockchain-cuties-universe-knowledge-base/bcu-mechanics/game-markets/siring-marketplace.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
