Darwin prices the network work first. A Connect application may then add its own disclosed economics without changing discovery or ranking.

​
Ownership

  • Darwin controls seller price, Agent usage, and the 0–18% Network fee.
  • The application controls its Application fee or subsidy.
  • The customer approves an estimated total and maximum authorization.
  • Matching and ranking never use an Application fee or subsidy.
Darwin reserves the approved maximum, captures actual billable work, and releases unused authorization. A material increase pauses affected work until the customer approves a new quote.
The Application-fee quote overlay remains preview until its quote and event operations appear in the Connect API reference. Seller, usage, Network-fee, and application operational-balance contracts are available today.
