x402 payments for AI agents
AI agents can encounter paid APIs, data, compute and machine services while completing tasks. x402Facilitator.si provides a payment boundary where organizations can define what an agent may buy, how much it may spend, which services are allowed and which wallet or signer must authorize the transaction.
Budgeted payment authority
Agent wallets and delegated sessions can be bounded by spending policy instead of receiving unlimited wallet authority. The facilitator can keep payment authorization separate from the model that decides a service is useful.
Machine-readable payment state
Agents benefit from explicit states such as payment required, verified, submitted, confirming, settled or failed. Status and receipt records make retry and recovery behavior easier to reason about than an opaque checkout flow.
Human and organization control stays above the model
The AI model can help select tools, inspect payment requirements and operate workflows, but wallet ownership, signing authority, policy and emergency controls remain outside the model itself.
