Can an agent stream a completion that calls a tool with OpenRouter API?

A person steps in at setup: a person hands over a key or token, a person signs up or registers a client for it and a person replaces or revokes its access when it must change. Job reachable, not yet run.

Who does each step

Whether the agent handles it alone or a person has to step in.

  1. 01

    Discover

    Machine

    The vendor's own machine-readable documents lead an agent to the job's interface.

  2. 02

    Authority

    Workaround · setup

    A person hands the agent a key or token.

  3. 03

    Onboard

    Workaround · setup

    A person signs up, or registers a client, for the agent.

  4. 04

    Pay

    Not applicable

    Nothing to pay for the job.

  5. 05

    Confirm

    Machine

    A failure comes back typed, in its answer or as its spec declares, so an agent can tell a failure from a success.

  6. 06

    Sustain

    Workaround · setup

    A person replaces or revokes the agent's access when it must change.

A person once, at Authority: handing over a key or token.

A person once, at Onboard: signing up or registering a client for the agent.

A person once, at Sustain: renewing, replacing or revoking its access.

Not A+ yet: OAuth that lets an agent register its own client would turn handing over a key or token into a one-time consent; a way for agents to register (auth.md, a sign-up API, or OAuth with client registration) would let the agent register itself; a key-management API, or OAuth refresh and revocation, would let the agent keep its access alive.
