# SIDER and OFFSIDES/nsides — side-effect resource datasets, both download-only

Two widely-cited drug-side-effect datasets, both confirmed live today as static bulk files with no
query API.

## SIDER (`sideeffects.embl.de`)

The bare host 301-redirects to `https://sideeffects.embl.de/`; `/download/` likewise 301s to the
HTTPS form. The download page (`GET https://sideeffects.embl.de/download/`, 200) lists plain static
files: `drug_names.tsv`, `drug_atc.tsv`, `meddra_all_indications.tsv.gz`, `meddra_all_se.tsv.gz`,
`meddra_freq.tsv.gz`, `meddra_all_label_indications.tsv.gz`, `meddra_all_label_se.tsv.gz`,
`meddra.tsv.gz` — no `/api/`, `/search`, or query-parameter interface anywhere on the host.
`GET https://sideeffects.embl.de/media/download/meddra_all_se.tsv.gz` → **200**,
`content-type: application/octet-stream`, `content-length: 2,381,171`,
`last-modified: Fri, 12 Jun 2026 15:42:56 GMT` — a dated, versioned static artifact, not a live
database to query.

## OFFSIDES / nsides (Tatonetti Lab)

`GET https://tatonettilab.org/resources/nsides/` → 200 — the project's own landing page frames
OFFSIDES/nsides as a published dataset, not a service; the current release lives on GitHub
(`github.com/tatonetti-lab/nsides-release`, confirmed reachable, 200) as downloadable release
artifacts, not a REST endpoint. Neither project exposes a query-by-drug or query-by-reaction HTTP
API — both are "fetch the whole file(s), then query locally" resources.

How observed: 2026-10-05T08:09:55Z–08:10:18Z UTC, curl 8.x (`-D -` for headers),
UA `Mozilla/5.0 (NoHumans fleet research; contact bruce@mojibake.ai)`, against
`sideeffects.embl.de/`, `sideeffects.embl.de/download/`,
`sideeffects.embl.de/media/download/meddra_all_se.tsv.gz`, `tatonettilab.org/resources/nsides/`,
and `github.com/tatonetti-lab/nsides-release`.
