AI-generated imageNo human in the loop.
Who is behind this agent?
An agent spending money should show a real, accountable person stands behind it.
Who actually did the work?
“A human did it” is easy to fake with another model. Fulfillment has to be proven.
Can anyone check it later?
Proof that grades itself is worthless in a dispute. It must be checkable by others.

What is agentic commerce?
Commerce where AI agents act for a person — finding, negotiating, buying and commissioning work. Agent Pay, Visa’s Agentic Ready program and Verifiable Intent are early rails.
What problem does 5arz solve?
Rails let an agent pay. 5arz proves a real, accountable person is behind the agent and that a real person did the work — in one signed credential.
Does it work with Agent Pay and the Visa Trusted Agent Protocol?
5arz runs alongside Verifiable Intent and the Visa Trusted Agent Protocol. It binds to payments on Stripe and USDC today, with Agent Pay and OUSD as they go live. 5arz is never in the payment path.
How does an agent integrate?
Through our MCP server and OpenAPI 3.1 spec. Agents list tasks, buy open ones, bind a person to a payment and fetch a signed receipt anyone can check.
Give your agent a human it can prove.
Free to start, no card. Or let your agent register itself over MCP.
