Autonomous agents in ArcenPay are non-human entities that negotiate pricing, pay for API access via HTTP 402, and consume metered entitlements without manual intervention. Agents operate with cryptographically restricted session keys, strict hourly and daily spend velocity limits, and auto-topup dispatch rules to ensure autonomous continuous operation.

Velocity & Spend Controls

To protect autonomous agent operations from unintended drain or compromise, ArcenPay enforces three layers of velocity limits:
  1. Per-Transaction Cap (maxPerTx) Maximum micro-units an agent can transfer or commit in a single transaction.
  2. Hourly Spend Velocity (maxSpendPerHour) Rolling 60-minute spending window cap.
  3. Daily Spend Velocity (maxSpendPerDay) Rolling 24-hour spending window cap.
All limits are verified off-chain via facilitator keepers and on-chain via smart contract session vaults.
