Brex
AnnouncedBusiness credit cards and spend management platform. Brex provides APIs for corporate card issuance, expense tracking, and payment controls. AI agent support is on the roadmap.
Brex has announced plans to support UCP as a participant. No public endpoint is available yet.
Brex offers developer APIs for managing corporate cards, budgets, and expenses programmatically. The platform targets fast-growing companies that need spend controls and real-time visibility without legacy banking overhead.
UCP integration is planned. When live, agents will be able to authorize purchases within policy limits, flag out-of-policy transactions, and sync expense data to accounting systems automatically.
Why This Matters for UCP
Brex aims to enable AI agents to make authorized corporate purchases within pre-configured spend policies, bringing spend control intelligence to agentic commerce workflows.

The UCP payment handling is correct. Latency is a bit higher than our non-UCP flows, but still within acceptable bounds for checkout.

Used this to add UCP checkout support to our app. The spec compliance is exact — everything we tested against the conformance suite passed.

Payment token exchange is solid. We process UCP transactions across multiple merchants and have not hit any protocol-level issues in three months.
