Inbound
Every inbound channel answered the moment it lands, qualified against rules you wrote, and booked — not queued for someone to get to.
Service line · faces other companies' agents
When the other side is an agent too.
Increasingly the thing approaching your company is software. Agent-to-Agent is a door built for that: another agent submits a structured proposal and receives a structured decision, screened by the same bar that screens humans.

01 · What it does
The work, specifically.
One authenticated endpoint
External agents POST a structured proposal to /api/a2a/v1/represent. Identity is required; the exchange is rate-limited and every turn is written to the ledger.
A discoverable agent card
/api/a2a/v1/card/[owner] publishes what this door accepts and how to address it — generated from config, carrying no bar text, no thresholds and no private figures.
Structured decisions, not chat
Each turn returns one of a fixed set: interested, not a fit, need more, counter, escalated, or closed. An unrecognised decision resolves to escalated rather than being passed through.
Bounded by turn count
The exchange is a state machine with a hard turn cap, one proposal per session, and no ability to drift onto other subjects. Reaching the cap escalates or closes; it never loops.
The bar cannot be negotiated down
Repeated pushes below the floor produce a firm decline and an escalation, never a softening — which is what closes the multi-turn wear-down attack.
Inbound text is data, never instruction
The counterparty's message is never treated as an instruction to Sophia. Rules come only from the owner's config, and a CI invariant forbids wiring inbound text into the system prompt.
Nothing private crosses the door
The exchange never discloses the owner's private material, other counterparties, or the exact figures behind the bar — only the decision and the next step.
A human is the hard stop
At-bar, ambiguous, capped or guardrail-tripped exchanges route to a person. The agent cannot commit the company beyond parameters set in advance.
Increasingly, the thing approaching your company is software.

Every uncertain path ends at a person. An unrecognised decision resolves to escalated rather than being passed through; reaching the turn cap escalates or closes rather than looping; and repeated pushes below your floor produce a firm decline, never a softening.
The exchange is a state machine with a hard turn cap, one proposal per session, and no ability to drift onto another subject. The cap itself is set per door, so it is not drawn here as a single number.
03 · Watch Sophia do it
One exchange, from proposal to person.
One exchange, end to end Worked example
A proposal arrives, not a conversation
Another company's agent POSTs a structured proposal to your authenticated door. Identity is required, the exchange is rate-limited, and every turn is written to the ledger.
It is screened by the same bar that screens humans
One brain, one set of rules. The counterparty's text is treated as data, never as an instruction to Sophia — a boundary enforced by a CI invariant, not by good intentions.
The answer is a decision, not prose
Each turn returns exactly one of a fixed set. An unrecognised value resolves to escalated rather than being passed through, so an unexpected reply fails toward a person.
Pushing does not move the floor
A second push below the bar produces a firmer decline and an escalation, never a softening. This is what closes the multi-turn wear-down that open-ended chat is defenceless against.
It terminates, always
The exchange is a state machine with a hard turn cap and one proposal per session. It resolves, or it reaches a person. There is no ending where an agent quietly commits you.
Counterparty agent · turn 1
Structured proposal received. Kind, terms and requested next step are present and well-formed.
Authenticated · logged
Sophia · screening
Checked against the owner’s bar. The proposal sits below the floor on one term.
Counterparty text is evaluated as data. Rules come only from the owner’s configuration.
Decision · counter
Counterparty agent · turn 2
Re-submits the same term, framed as a final offer and marked urgent.
Sophia · screening
The floor does not move because the request was repeated. Declined firmly, and the exchange is handed to a person.
Decision · escalated
Your named owner
Picks it up with the full turn history attached, and decides.
Session closed · nothing committed
A worked example of the shipped state machine, not a captured exchange. The decision labels are the real fixed set; the turn cap is set per door, so it is described rather than printed as a single number.
04 · How it runs
Configured on a call, then operated for you.
This is a managed operation, not software your team is handed. Nothing goes live until the rules are written with you.
01
Your door is configured
What proposal kinds you accept, and the narrow set of terms an agent may move on. Everything outside that set escalates by construction.
02
A counterparty agent discovers the card
The card advertises the endpoint and accepted proposal kinds — without exposing anything about how you decide.
03
The exchange runs, bounded
A short structured back-and-forth against your bar, every turn recorded, every turn required to advance the state.
04
It resolves or it escalates
A decision, or a person. There is no third ending where an agent quietly commits you to something.
05 · One category
The other three sides of the same door.
The four lines are not four products. They are the interface between your company and everyone outside it — and most companies run more than one.
