post/feed-gateway/v1/merge1 credit

Merge up to 10 feeds into ONE de-duplicated, date-sorted stream. Duplicates are detected on a canonical link key (tracking params stripped) falling back to guid/title. Each item carries its source_feed.

Working example
Parameters

Feed URLs to merge (max 10). Each URL is independently SSRF-guarded and fetched concurrently; one bad feed never fails the whole call.

Max items returned (1-200, default 100). Out-of-range values are clamped, never rejected. (1–200)

Sort direction (applies when sort_by is not feed_order).

Remove duplicate stories across feeds (default true).

Only items published at/after this date (ISO 8601, e.g. 2026-06-01 or 2026-06-01T12:00:00Z).

Only items published at/before this date (ISO 8601).

Include the raw item HTML body as content_html (capped 30 KB). Off by default: summary is always returned as clean plain text.
