Connect agents to the content they need.
Use your organisation’s knowledge and licensed sources together. Content owners set the terms; agents carry the authority to use them.
Common Measure is building this network. What is available today is on How it works and Install.
What each side gets
For operators
- Connect licences and supplier accounts once. Give each agent access for its task, with a budget and an expiry.
- Keep one source record across internal documents, licensed content and the open web.
- Connect through Edge or build the same interfaces into your own agent system.
For suppliers
- Choose access collection by collection: your own agents, named partners or organisations with a licence. Keep the rest private.
- Verify who an agent acts for, what it may do and which licence covers the request.
- Receive reports of what was released and used at your chosen destination, without passage text.
Edge, Hub and CM Attestation
Edge
Checks source access, licences, budget and incoming content before passing it to the agent. Keeps the record.
Hub
Connects agents to shared policy, supplier accounts and licences. Arranges reporting and payment, including duties that outlast a task.
CM Attestation
Names who stands behind the agent’s permission and obligations. Content owners verify it with Hub or another recognised issuer.
Extensions
Custom extensions
Build security checks and content tools for your organisation using the same public extension contract as specialist developers.
Build an extensionPrivate catalogue
Keep in-house extensions private to your organisation. Approve what your agents run, set required checks and manage settings through Hub.
Extension marketplace
Choose free or paid extensions from Common Measure and specialist developers. Review their permissions and approve them before they reach your agents.
From request to report
“Compare our internal guidance with licensed external commentary. Give me a short summary with sources.”
Registered

The instance receives authority for one task, bound to a responsible operator before any content moves.

- The licence https://theguardian.com/license.xml permits AI input under payment type subscription, and this edge holds no settlement rail, so the payment term is unmet.

- Nothing. No status, no bytes, no hash.
Reads
Edge · Supplier
The supplier checks the attestation with Hub and releases content directly to the Edge. Hub never sees it. Retrieval and later use are recorded separately.

When it goes wrong
Access outside the licence
The request is refused before content is fetched, with the reason recorded.
Internal content
The organisation’s own permissions apply. Internal content never enters publisher reporting.
Reporting destination unavailable
The report stays undelivered, held for recovery. Any grace period requires the publisher’s agreement.
Task fails or is cancelled
The agent stops. The durable service keeps its outstanding reporting duties.
A read the Edge did not carry
Recorded after the fact as observed. Never merged with a mediated crossing. The record says what it did not see.
