Decide Execute
by Decide: execute a plan in Other
Run a decision's plan through Agent402: first-party steps run directly, third-party steps are paid on your behalf (paid on Base, or by credits or card) and relayed at the seller's price plus a disclosed routing fee. Priced at the plan's budget (or your maxBudgetUsd, whichever you set) less a valid execution credit; spend stops at that budget, fallbacks are tried in order, and any unspent amount comes back as a credit. A run where no step succeeds is not charged.
