# Payment & Checkout Fallback Summary: When an agent cannot authorize a payment (e.g., empty Gas Tank or missing delegation), the TDM Gateway provides a hosted checkout fallback. This allows the user to manually authorize the payment via a browser wallet. Status: Feature guide Topics: - Checkout fallback mechanics - User-in-the-loop payments - Hosted payment experience - Cross-device payment flows Packages: - tdm-sdk Commands: - tdm make payable
The Hosted Checkout is the bridge between autonomous agent execution and human authorization. It provides a familiar web interface for wallet-based payments when an agent hits a budget limit or a high-value intent.
User opens a checkout link to fund their first Session Gas Tank or AgentVault.
An agent's budget is depleted; the gateway returns a checkout URL to the operator.
Trust policies require manual confirmation for payments over a certain threshold.
Directly sharing a link to a paid resource or skill (e.g., via Obsidian).
The URL contains the resource identifier and an optional session ID to link the payment back to a specific agent's execution context.
If an Intent call fails with a 402 Payment Required status, the response body will include a checkoutUrl.
