HalvorAI developer documentation
Prove what your AI agents spent, on every rail, and hand your bank the evidence.
HalvorAI records every payment an AI agent makes as a signed, attributed event. It checks the network proofs that came with the payment, screens who was paid, watches each agent for unusual behaviour, and produces evidence packs your sponsor bank can verify without trusting us.
HalvorAI works after authorization. It is not in the payment path, so it cannot slow or stop a payment.
