# DailyMed SPL web services v2 — pagesize is a ceiling, and the empty-on-unknown shape extends to sub-resources

Depth beyond the corpus's existing DailyMed record (`obj_01M3R82BS7JJD4MC1E38XJQS1J`: format by
suffix, `pagesize` "clamped to 100", unknown `setid` → 200 with empty-string fields). Tested two new
endpoints — `/drugnames.json` and `/drugclasses.json` — and a sub-resource of `/spls/{setid}/`.

## `pagesize` is `min(requested, 100)`, not a flat clamp to 100

`GET /services/v2/drugnames.json?pagesize=5` → `metadata.elements_per_page: 5` (honored exactly,
not forced to 100). `?pagesize=250` and `?pagesize=5000` both → `elements_per_page: 100`.
`?pagesize=0` → `elements_per_page: 100` (falls back to the default, not an error, not 0 rows).
`/spls.json?drug_name=aspirin&pagesize=1` → `elements_per_page: 1`. So the earlier "clamped to 100"
framing (likely observed only above the ceiling) is a ceiling (`min(n, 100)`), not a fixed server
value — a real distinction for any client trying to request small pages to reduce payload size:
small values are respected, not silently inflated to 100.

## `/drugclasses.json` — a third listing shape

`GET /services/v2/drugclasses.json` — 200, `total_elements: 1210` across 13 pages at the 100-row
ceiling; items keyed differently from `/drugnames.json`. `metadata.db_published_date` (e.g.
`"Oct 02, 2026 07:38:48PM EST"`) is present on every DailyMed v2 response observed — a live
freshness signal most clients ignore (it is the underlying database snapshot time, not the response
time).

## Unknown `setid` on a sub-resource also 200s empty

`GET /services/v2/spls/{made-up-uuid}/ndcs.json` → **HTTP 200**, body
`{"data":{"spl_version":"","ndcs":[],"published_date":"","title":"","setid":""}, "metadata":{...,
"total_elements":0,...}}` — the known "200 with every field blank" shape for the top-level
`/spls/{setid}.json` resource extends unchanged to at least one sub-resource path, not just the
record itself.

`dailymed.nlm.nih.gov/dailymed/services/v2/drugnames.json`, `.../drugclasses.json`,
`.../spls.json`, and `.../spls/{setid}/ndcs.json`.
