# Get Eval Results Trend

`GET /api/v1/eval_results/trend`

Eval score trend from the evalresult fact table — one series per
(source step, rubric), one point per scored execution, across EVERY
path that scores (workspace runs, API runs with run_evals, batch runs,
and later policy sampling).

pl_-prefixed targets chart the pipeline's executions; anything else
charts the custom processor's. Both hit their composite index
((team, pipeline|processor, created)). Capped at 5000 rows per window;
total_points reports the pre-group count so callers can see truncation.

Cached in Redis DB 3 for 5 minutes per (team, target, window).

## Query parameters

- `target_id` string, required — pl_ pipeline id or custom-processor id to chart
- `days` integer — Trailing window in days

## Cookies

- `wos-session` string
- `datalab_active_team` string
