Can an agent stream a completion that calls a tool with Anthropic API?
Who does each step
Whether the agent handles it alone or a person has to step in.
- 01
Discover
MachineThe vendor's machine-readable docs show the agent where and how to call this job.
- 02
Access
Workaround · setupYou give the agent a key or token.
- 03
Onboard
Workaround · setupYou sign up or register a client for the agent.
- 04
Pay
Workaround · setupYou add a payment card at the vendor's checkout.
- 05
Confirm
MachineThe response or specification defines errors the agent can distinguish from success.
- 06
Sustain
Workaround · setupYou replace or revoke the agent's access when it needs to change.
- Access: handing over a key or token.
- Onboard: signing up or registering a client for the agent.
- Pay: adding a payment card.
- Sustain: renewing, replacing or revoking its access.
To remove these handoffs: support OAuth client registration so the agent can register its own client and ask for consent; provide an agent registration route, such as auth.md, a sign-up API or OAuth client registration; support payment in the request, such as x402 or MPP, so setup does not require a person to add a card; provide key management or OAuth refresh and revocation so the agent can maintain its own access.
