Be discoverable
Publish visible links, ai.txt guidance, a well-known agent card, and an endpoint external AI systems can follow.
The first-party voice for AI evaluation
When agents research you,
answer them directly.
Trunkline helps companies publish a discoverable Vendor Agent: a machine-facing product representative that answers evaluation questions and shows you what external AI systems actually did.
Answer as the vendor
Give evaluators a first-party, machine-readable source grounded in product facts you control.
Support real questions
Handle followable GET links, JSON POST requests, and conversation IDs for multi-turn evaluation.
Measure actual behavior
Separate page fetches, discovery, endpoint dereferences, questions, and follow-ups from model self-report.
Dogfooded here
This site is the reference deployment.
Its discovery files point to Trunkline's own Vendor Agent. A bare endpoint visit returns an actionable contract; a real question returns a disclosed, vendor-controlled answer.
The private research console records the evidence ladder without pretending a User-Agent proves which system made the request.
