Paitify launches real-time spend authorization engine for AI agents

KEY FACTS

Paitify has released a spend policy engine for autonomous AI agents that provides real-time transaction authorization.
The system enforces rules before payment in a single API call, automatically approving or rejecting transactions.
It uses Redis counters and in-memory rule evaluation to deliver zero-latency decisions and generates chained audit logs.
It is compatible with Claude and MCP clients, and supports RSA-signed tokens for offline verification by the payment layer.

PHYSIX OBSERVATION

As AI agents shift from conversation to autonomously executing procurement and infrastructure tasks, the risk of losing control has become the biggest obstacle to enterprise adoption. Paitify has refactored traditional human approval logic into machine-readable policy-as-code, filling the infrastructure gap for trust and compliance in the agent economy. This "authorize first, execute later" model with a tamper-proof audit chain may be the necessary safety foundation before autonomous agents can be deployed at scale.
