China's first cross-terminal agent interoperability protocol released, merchant payment fees cut to 60%

China's first cross-terminal interconnection protocol for AI agents has been released, according to Sina Finance, marking an important step toward interoperability standards in the agent industry.

Cross-terminal interconnection means agents can work across different devices, letting the same agent capabilities move between scenarios without being adapted for each terminal individually.

Alongside the protocol release, merchant payment fees are discounted to 60 percent of the standard rate, a commercial incentive widely read as a signal that platforms are actively courting merchants into the agent ecosystem.

The protocol suggests agents are moving from isolated tools to a connected network: lower integration costs for developers and concrete fee savings for merchants give every side a reason to participate.

For the industry, the protocol fills a gap in domestic agent interconnection standards and provides infrastructure for agent commercialization to move from concept to deployment.

What to watch next is the protocol's technical specification, the first batch of terminals and platforms to adopt it, and the scope and duration of the fee discount.
