Moov keeps closing the gap between what its API can do and what the Dashboard exposes.
Moov is a payments platform shipping on a versioned API train, currently with v2026.10.00 in preview and v2026.07.00 recently landed. The last two months added FedNow alongside RTP for instant bank credits, surcharging, payout fees that merchants can pass to recipients, user-defined amounts on payment links, and custom Dashboard roles. The consistent shape of a release is an API capability followed weeks later by the Dashboard surface for it.
Stigg adds credit reservation and settlement for AI operations days after its agent SDK.
Stigg can now reserve credits before an AI operation starts and settle the actual cost when it finishes. It follows the beta Agent Governance SDK, an open-source library built on Stigg's entitlements engine. Earlier October releases added an Airwallex billing backend, credit usage grouped by feature and a Stripe Projects listing.

The consistent shape of a release is an API capability followed weeks later by the Dashboard surface for it.
Two threads run in parallel. One is fee mechanics — surcharging, tax moved into amountDetails, payout fees, and now fee plan reassignment — steadily giving platforms more control over who pays what and when they agree to it. The other is self-service: pricing disclosure in the onboarding Drop, resumable onboarding, custom roles, and richer partner onboarding all reduce the number of moments a customer has to talk to Moov support. Both point at Moov being operated by platforms embedding payments rather than by merchants directly.
Fee plan agreement updates are still in-development on v2026.10.00, so expect that to reach general availability along with the Dashboard controls to match. The recurring gap between an API capability and its Dashboard equivalent suggests the next Dashboard releases will pick up fee plan management.

Credits have become Stigg's main pricing unit, and the product is adapting them to AI workloads whose cost isn't known up front. Reserve and settle, together with the governance SDK, turns the entitlements engine into a spending control for agents.
Expect the governance SDK to use reservations directly for agent limits, and more reporting on reserved versus settled usage.
