News search API: Google News results plus Google News RSS, merged and clustered by story, so each row is one story with its best outlet, how many outlets cover it and links to the others. Freshness window in hours (1 h to 1 y), country and language. Ranked by outlet authority, coverage and recency. Tracking parameters removed from links.
Verdict: live. The unpaid GET reached a valid 402. The live amount equals the catalog price.
