To enforce spending limits on autonomous agent payments, configure explicit per-task and per-session budgets within a spending policy. The system blocks transactions that exceed these defined limits, preventing overspending when agents pay for external API calls or services.

Non-custodial wallets secure autonomous agent transactions by letting agents hold their own keys via ERC-4337-style accounts. The orchestration layer enforces spending policies before delegating transactions, reducing custodial risk and preventing unauthorized key access.

If the payment service is unreachable, the agent payment system uses a fail-closed approach. This means the system automatically blocks pending transactions and halts payment processing to prevent uncontrolled spending or unauthorized transfers during connectivity loss.

Yes, you can restrict which external services your AI agent pays by configuring recipient allowlists within the spending policy. The system enforces these allowlists alongside rate limits and budget caps before approving any outbound transaction.

Explicit spending policies are required for AI agent automation to define strict per-task budgets, recipient allowlists, and rate limits. These policies ensure the orchestration layer can validate and enforce transaction rules before delegating non-custodial wallet payments.
