List unread account signals

AUTHENTICATIONBearer token · profile:readAUTHORITATIVE OWNERnotificationsCONTRACT AUTHORITYGenerated Rust OpenAPISTATUSSource ready · production listed

PURPOSE + BUSINESS CONTEXT

List only unread operational signals for the authenticated profile and workspace, with the same bounded cursor and no-authority guarantees as the complete inbox.

WHEN THIS CALL IS USEFUL

Use for badges, attention queues, and agents that process only unacknowledged account signals without downloading read or archived history.

OUTCOME · Discover

What changes

Read-only projection; it grants no mutation, settlement, traffic, or authority change.

WHY IT MATTERS

  • Gives people and agents a contract-backed way to discover unread account signals.
  • Provides a bounded attention queue with stable references and unread state while preserving the owning domain as the authority for any consequential action.

ISOLATION + AUTHORITY

Profile, workspace, notification, delivery channel, read or archive status, referenced resource, and owning-domain lifecycle remain distinct. Reading, marking, or archiving a signal changes only inbox presentation state and never authorizes, executes, reverses, or resolves the referenced business action.

BEFORE YOU CALL

  • Authenticate at the documented boundary: bearer+scope.
  • Use the live OpenAPI schema as the authority for the exact request shape and response model.
  • Resolve the authenticated profile and workspace plus the canonical resource reference and owning domain for any signal that may require action.

WHAT TO DO NEXT

  • Use the signal's canonical resource reference to open and re-read the authoritative domain record before offering a response.
  • Advance the cursor or refresh the unread aggregate without treating inbox presence or absence as resolution of the underlying event.

AGENT GUIDANCE

  • Use unread account signals only for the purpose and lifecycle stage described by this operation; do not treat it as authority for an adjacent action.
  • Use the live OpenAPI schema as the authority for the exact request shape and response model.
  • Distinguish signal delivery, unread state, acknowledgement, archival, referenced-resource state, and resolution in the authoritative domain workflow.
  • Use response links and canonical identifiers instead of constructing internal service URLs or scraping the website.
MACHINE CONTRACT

The exact deployed parameters, schemas, responses, security requirements, and Hybrid-Chain agent metadata are authoritative at this operation's production OpenAPI JSON Pointer. The readable tables below add integration guidance; the deployed OpenAPI controls if guidance and the machine contract ever differ.

INTEGRATION DECISION
CALLER ACTION
Accept the returned representation or receipt, then use the signal's canonical resource reference to open and re-read the authoritative domain record before offering a response.
RETRY SAFETY
For another page, send the returned opaque cursor unchanged with the same filters. Restart without a cursor when a new snapshot is required.
STATE RECONCILIATION
Use returned identifiers and versions as the comparison point for later reads. Refresh the specific profile or account projection and compare tenant, profile, lifecycle, and version identifiers before retrying.
400The cursor or limit is invalid.Request must change · JSON RESPONSE+
{
  "code": "invalid_notification_query",
  "message": "The cursor or limit is invalid."
}
INTEGRATION DECISIONinvalid_notification_query
CALLER ACTION
Rebuild the request from the live OpenAPI operation and correct the rejected method, media type, header, parameter, or body field.
RETRY SAFETY
Do not retry the same invalid request. A corrected read may be sent as a new attempt.
STATE RECONCILIATION
Compare the submitted values with the documented constraints before another call. Refresh the specific profile or account projection and compare tenant, profile, lifecycle, and version identifiers before retrying.
ESCALATE WHEN
Escalate when a fresh session resolves to an unexpected tenant or profile, or when an account lifecycle receipt cannot be found after reconciliation.
401The bearer credential is missing or invalid.Authentication required · JSON RESPONSE+
{
  "code": "invalid_credentials",
  "message": "The bearer credential is missing or invalid."
}
INTEGRATION DECISIONinvalid_credentials
CALLER ACTION
Discard the rejected credential, complete the documented authentication or reassertion flow, and rebuild any request signature with fresh timestamps and nonces.
RETRY SAFETY
Retry only with a newly valid credential and fresh replay-protection values. Do not replay an expired signature.
STATE RECONCILIATION
Authentication failed before an authoritative read was returned for the authenticated profile, tenant brand, referral, funding, and account-lifecycle projections.
ESCALATE WHEN
Escalate when a fresh session resolves to an unexpected tenant or profile, or when an account lifecycle receipt cannot be found after reconciliation.
403The credential lacks profile:read or the owner boundary is unavailable.Authority or policy denied · JSON RESPONSE+
{
  "code": "insufficient_scope",
  "message": "The credential lacks profile:read or the owner boundary is unavailable."
}
INTEGRATION DECISIONinsufficient_scope
CALLER ACTION
Verify the exact scope, tenant or workspace membership, owner boundary, step-up purpose, feature policy, and resource eligibility. Never broaden authority automatically.
RETRY SAFETY
Do not retry until the missing authority or policy condition has been deliberately resolved with least privilege.
STATE RECONCILIATION
Confirm the caller and resource resolve to the same authority boundary for the authenticated profile, tenant brand, referral, funding, and account-lifecycle projections.
ESCALATE WHEN
Escalate when a fresh session resolves to an unexpected tenant or profile, or when an account lifecycle receipt cannot be found after reconciliation.
503The authoritative owner-scoped inbox is unavailable.Dependency unavailable or outcome uncertain · JSON RESPONSE+
{
  "code": "notifications_unavailable",
  "message": "The authoritative owner-scoped inbox is unavailable."
}
INTEGRATION DECISIONnotifications_unavailable
CALLER ACTION
Treat the failure as transient and preserve the last known good representation without presenting it as fresh.
RETRY SAFETY
Retry with bounded exponential backoff and jitter; stop after the integration's failure budget is exhausted.
STATE RECONCILIATION
Refresh the specific profile or account projection and compare tenant, profile, lifecycle, and version identifiers before retrying.
ESCALATE WHEN
Escalate when a fresh session resolves to an unexpected tenant or profile, or when an account lifecycle receipt cannot be found after reconciliation.

OPERATIONAL NOTES

Security and lifecycle guarantees

  • Use for attention badges and queues that do not need read or archived history. The route always applies UNREAD; use the complete inbox for any other lifecycle.
  • Processing the referenced workflow and acknowledging its signal are separate. Complete or reconcile the owning workflow before marking READ when that distinction matters.
  • The same owner, no-store, routing-metadata, and no-domain-authority guarantees as the complete inbox apply.

Legacy calls replaced by this operation

If you maintain an older integration, use this map to find the V2 replacement. Do not translate the old request field-for-field: rebuild it from the V2 parameters and schemas above because identity, authorization, replay protection, and response semantics may have changed.
