Sui announced at Basecamp that it has partnered with Alibaba Cloud to integrate Alibaba Cloud services into Sui Agent Payments. Agents can pay per use with stablecoins on Sui, where users set a budget and allow agents to complete payments autonomously. The announcement did not disclose specific interface pricing or launch dates.

This payment layer does not require registration. Each service call has a price per invocation, and agents pay according to usage. Settlements are made in USDC, completed before upstream execution; the gateway first returns HTTP 402, checks against owner authorization, and resources are delivered only after on-chain event confirmation. Each transaction corresponds to a summary that can be opened on Suiscan.

Owners set an expenditure account based on assets, limiting agents to available services, total budget, per transaction cap, and expiration time. Restrictions are enforced on-chain at settlement and can be revoked at any time. When accessing through MCP, gas fees are covered by sponsors, leaving agents with only the service cost. An official example shows that a call priced at $0.001 remains $0.001. The directory is provided via SKILL.md and JSON endpoints, allowing agents to compare prices. MCP can register with Claude Code or Codex.

In the same week, Sui's core developer Mysten Labs and Google Cloud announced a verifiable agent arbitration layer. Prompts, model outputs, tool calls, and strategy decisions remain under customer control in Google Cloud Storage, with cryptographic proofs stored in Walrus, coordinated by Sui. This layer receives assistance from Agent Payments, recording authorizations, expenditures, and service deliveries according to x402. The official launch date has not been announced, with enterprise pilots starting first.

x402 repurposes the idle HTTP 402 into a payment status code. The Linux Foundation announced the operational launch of the x402 Foundation on July 14, with Coinbase having handed over the protocol. Members include Visa, Mastercard, Stripe, Adyen, American Express, Amazon Web Services, Google, Circle, and Shopify. The foundation reported approximately 75 million transactions totaling $24 million over the past 30 days, mostly involving machine calls under $1.

The buyer is the agent holding expenditure authorization, and the seller is the cloud interface priced per use. The event is driven by Basecamp's release, shifting funds from preloaded bills to USDC settlements before calls. Beneficiaries include interface providers who do not want to open merchant accounts and agents needing receipts, while traditional monthly subscription and key-based billing cloud consoles face pressure. Alibaba Cloud is entering the directory, not an exclusive channel.
