## Changelog

### 0.5.1 (unreleased)

- Ship `trendDetail` end-to-end: every `searchTerm` row now always carries `trendDetail` (object or `null`) derived from `interestOverTime` — `averageInterest`, `direction` (up/down/stable by ±5 growth), `peak`, `growthRate` (`null` on a zero-start series ending above 0), `volatility` and `trendScore` (0–100). It is added to the output example and "What you get" table in the README, added to the dataset schema view, and covered by tests (normal, sparse/partial, zero-start, missing). Points with `hasData` false are skipped, and a spend-cap cut that removes `interestOverTime` also nulls `trendDetail`.
- Add Trends + Shopping unified view: new optional inputs `includeShoppingProducts` (default off) and `shoppingMaxProducts` (default 10) put Google Shopping products (title, numeric price, original price, merchant, rating, review count) in the same `searchTerm` row as the trend data, with `shoppingSourceUrl` for every product. Shopping uses the Google SERP proxy and adds no per-product charge; failures are reported in `errors.shoppingProducts`.

### 0.5

- Add `geoResolution` (`COUNTRY`/`REGION`/`CITY`/`DMA`, default `REGION`) and `includeLowSearchVolumeGeos` (default `false`) for `interestByRegion`, enabling city/DMA-level regional slices.
- Support comma-separated regions in `geo` (and alias `regionFilter`) for multi-region slices in one run; also accept comma-separated values in `trendingNowGeos`. Results are tagged by geo.
- Listing and README now lead with `onlyNewTrending` new-trends alerts/monitoring for SEO/content workflows, including an hourly webhook/Make/n8n alert recipe.

### 0.4

- Listing and README no longer promise related topics: Google's data endpoint returns none (checked 3 Nov 2026). `relatedTopics` is off by default, stays selectable, and fills if Google resumes sending it.

### 0.2

- `onlyNewTrending`: trending-now rows only when the country has not shown that search in the last 7 days (state in a named key-value store), with a `trendingNowSummary` row per country.
- An empty input returns today's US trending searches instead of failing (agents send `{}`); every input field has a default.
- Title "Google Trends API: Trending Now & Interest Over Time" (experiment exp-001); README with real sample rows, pricing examples, alert recipe, FAQ and limits.
- Canary covers a non-US geo (IN).
- Add trend detail metrics (average interest, direction, peak, growth rate, volatility, composite trend score) for search term rows based on interest over time data.
