## Changelog

### Unreleased

- Ignore unsupported hidden detail input so Trending Now runs never schedule redundant per-term work.

### 0.1.0 — 2026-07-29

First release. Two surfaces, billed as two separate events.

#### Keyword analysis

- Interest over time (weekly series), interest by region, and related + rising queries for any keyword.
- `averageInterest`, `peakInterest` and `peakDate` are derived from the returned series.
- Accepts a pasted `trends.google.com/trends/explore?q=…` URL as a keyword.
- Related topics are available when an authenticated session is supplied via the optional
  `googleTrendsSessionCookie` input; without it every other field is still returned and the
  record reports `relatedTopicsStatus: "AUTH_REQUIRED"`.

#### Trending Now

- Live trending terms per country with search volume, growth percentage, the related searches
  Google groups under each trend, start/end times and backing news article references.
- Windows of 4, 24, 48 or 168 hours; accepts a pasted `trends.google.com/trending?geo=…` URL.

#### Delivery

- Google rations these endpoints per keyword, so retries cycle across keywords in passes
  rather than hammering one term, and only the widgets still missing are re-requested.
- A previously fetched series is served from cache when the live fetch is rationed, labelled
  with `fromCache` and `cachedAt` so cached data is never presented as fresh.
- A keyword that returns no time series is still delivered — with `error: "NO_SERIES"` — and
  is never charged for.
