Terms of service
Last updated July 1, 2026 · Calmar by SIML Inc.
The service
Calmar runs an auction for purchases made by AI agents: connected stores compete for each order, the best offer for the buyer wins, and the order is passed to that store. Calmar is not the seller of any item and never takes custody of goods.
Test mode
While marked test mode, order flows run end to end (auction, stock, history) but no real card is charged and no goods ship. Do not treat test-mode orders as binding purchases.
Sellers
You must own what you sell, describe it honestly, keep prices and stock accurate, and ship promptly. You set your own transaction fee. It is charged only on completed sales and is reversed if the order is refunded.
Developers
You earn a share of the transaction fee on orders your agent places. Earnings stay pending through the return window and are reversed if the order is refunded or cancelled. Payouts go to the bank account you connect.
Buyers and agents
You are responsible for purchases made by agents you authorize. Autonomous purchases execute only where you have pre-approved them; everything else requires explicit confirmation.
Prohibited
Illegal items, counterfeits, recalled goods, weapons, and anything requiring a license to sell. We remove products and revoke keys at our discretion.
Liability
The service is provided as is. To the maximum extent permitted by law, SIML Inc.'s liability is limited to the fees Calmar earned on the disputed order.
