Purpose and usage

What this endpoint does

List published newsroom entries through a stable public contract with bounded pagination plus optional category and featured-content filters.

When to use it

Call this to populate a public newsroom or feed, discover entries by category, or select one canonical publication identifier for detail and verification.

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 news publications.
Makes public newsroom content available through a stable machine contract with bounded filters, canonical identifiers, and a separate verification path.

ISOLATION + AUTHORITY

Publication content, editorial classification, featured placement, canonical identifier, integrity evidence, source provenance, and external claims remain distinct. A published or verified article is public information; it grants no identity, policy, investment, wallet, payment, settlement, publisher, matching, or trading authority.

BEFORE YOU CALL

No bearer credential is required; apply bounded filters and canonical public identifiers where the contract provides them.
Use the live OpenAPI schema as the authority for the exact request shape and response model.
Use bounded public filters or a canonical publication identifier, and decide whether the consuming workflow also requires the separate integrity and provenance projection.

WHAT TO DO NEXT

Select a canonical publication identifier from the bounded result and open its detail contract.
Use the separate verification operation when integrity or provenance assurance is required; do not infer verification from listing presence.

AGENT GUIDANCE

Use news publications 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 publication availability, editorial metadata, publication time, later revision, content integrity, provenance verification, and the truth or current applicability of external claims.
Use response links and canonical identifiers instead of constructing internal service URLs or scraping the website.

INTEGRATION DECISION

CALLER ACTION: Accept the returned representation or receipt, then select a canonical publication identifier from the bounded result and open its detail contract.
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 application, credential or callback record; compare scope, key identifier, secret-display state, version, and revocation or rotation receipt.

INTEGRATION DECISIONinvalid_credentials

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 application, credential or callback record; compare scope, key identifier, secret-display state, version, and revocation or rotation receipt.
ESCALATE WHEN: Escalate when a secret-bearing result was lost, key or callback state is ambiguous, or least-privilege scope cannot be established.

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 application, credential or callback record; compare scope, key identifier, secret-display state, version, and revocation or rotation receipt.

OPERATIONAL NOTES

Security and lifecycle guarantees

news publications through the canonical Hybrid-Chain V2 interface. Authoritative owner: core-evidence-read-model.
The Rust gateway validates the public contract and routes only to the authoritative owner; clients never address internal services directly.
The tables and examples are derived from the current gateway source OpenAPI. Re-fetch the deployed OpenAPI before execution; deployment status is shown separately on this page.
Only parameters present in the OpenAPI operation are accepted; undocumented query keys fail closed with HTTP 422.

Reference version and availability details

This route is implemented in canonical gateway source and appears in the production OpenAPI snapshot observed 2026-10-02T23:27:55.510Z. Authentication, tenant, feature, venue, and market policy still apply.
