How to evaluate this
The honest benchmark for a trend pipeline is not how many items it can emit — it is how much of the emitted record you can verify. Measure three things: the share of trends whose source URL resolves, the share with a retained body, and the share whose provenance fields are populated.
- GET /v1/trends/{trend_id} returns the citation list for a trend, including canonical URL, publisher, author, word count, and fetch method.
- GET /v1/content/{trend_id} returns the retained bodies, with content_retained telling you plainly whether anything survived sanitisation.
- GET /v1/benefits reports aggregate counts of trends, retained documents, publishers, source URLs, and distinct fetch methods.
