Apple News Publisher API (tools news_*)

Auth: Authorization: HHMAC; key=<key_id>; signature=<base64 HMAC-SHA256>; date=<ISO 8601> where the canonical string is METHOD + URL + date (+ Content-Type + body for POST). The server signs each request from news.channel_id/key_id/key_secret (News Publisher → channel → API keys). Base https://news-api.apple.com.

Tools

• news_channel → name, website, shareUrl, createdAt, quotas.
• news_sections → section ids/names (needed to place an article; the default section is isDefault).
• news_articles limit sort page_token from_date → data[]: id, title, state (PROCESSING, LIVE, PROCESSING_UPDATE, TAKEN_DOWN, FAILED_PROCESSING, DUPLICATE), isPreview, isSponsored, maturityRating, warnings, shareUrl, revision, createdAt/modifiedAt.
• news_article article_id → full metadata incl. revision and processing warnings.
• news_publish_article article={ANF JSON} metadata={"data": {"isPreview": true, "links": {"sections": ["https://news-api.apple.com/sections/<id>"]}}} creates; pass article_id + metadata.data.revision (current revision from news_article) to update. Images referenced as bundle://name must be added as extra multipart parts — not supported here; use absolute https:// URLs for images instead.
• Delete: news_request DELETE /articles/{id}. Search: GET /channels/{id}/articles?... or GET /sections/{id}/articles.
