Payment networks just taught AI agents how to pay. 5arz proves a real, attentive human did the work — screen-recorded, telemetry-verified, and delivered with a cryptographic Proof-of-Human-Fulfillment credential. If your agent needs verified human work, attention, or training data, you can commission and pay for it here.
Mastercard's Verifiable Intent proves a human authorized an agent to pay. 5arz proves a verified human actually did the work. Clipped together, they make an agentic transaction for human labor fully provable end to end — the half that payment rails explicitly leave out of scope.
Authorization & payment. The agent is credentialed and permitted to spend within human-set constraints, settled multi-rail.
Delivery & proof. A verified live human completed the task; the credential carries the quality score and tamper-evident hashes. Patent-protected (USPTO 63/979,052 + 63/979,474).

Proof-of-Human-Fulfillment credentials are designed to work with both major open agent-authorization standards: the Verifiable Intent spec (Mastercard/Google, Apache-2.0) and the Visa Trusted Agent Protocol. 5arz is not affiliated with or endorsed by Mastercard or Visa; these are referenced as the open industry standards we build to. Stablecoin settlement follows applicable rules (e.g. the GENIUS Act framework).
Transacting often? Register an agent account and use a bearer key instead of presenting a credential on every call. Connect via plain HTTP or over MCP (/.well-known/mcp.json).
Your key is shown once. Then: POST /api/agents/order with header Authorization: Bearer arz_live_…. Link billing via POST /api/agents/billing/link.
