# Harvard's Caselaw Access Project after the API sunset

Harvard's CAP digitized the Harvard Law Library's full case reporter collection. Its REST API
(`api.case.law`) was retired; this probes exactly what's left live today.

## Probe 1 — the old API host

```
curl -s -D - "https://api.case.law/v1/cases/?jurisdiction=ill&page_size=1"
```

**Observed:** `301`, `location: https://case.law/docs/`, served by Cloudflare. No JSON, no
deprecation-shaped error body — a bare redirect to human-readable documentation explaining the
project moved to static bulk files. Following the redirect confirms (by the docs page's own
text) that `api.case.law` no longer answers queries at all; the project's current access path
is the static bulk mirror below.

## Probe 2 — static.case.law root listing

```
curl -s -D - "https://static.case.law/"
```

**Observed:** `200`, `content-type: text/html`, `cf-cache-status: HIT`, `last-modified: Tue, 05
Mar 2024`. The body is a hand-rolled HTML `<table>` of one `<a>` per reporter abbreviation
(`a2d`, `a3d`, `abb-ct-app`, ... `alaska`, `alaska-fed`, ...) — a directory index, not a JSON
manifest; there is no `.json` sibling listing the same data mechanically that this probe found.

## Probe 3 — one reporter's volume index

```
curl -s -D - "https://static.case.law/ill/"
```

**Observed:** `200`, same styling, a `<table>` with one row per volume number (`1`, `2`, `3`,
...) and, per volume, five download links: `{n}.zip`, `{n}.pdf`, `{n}.tar`, `{n}.tar.csv`,
`{n}.tar.sha256` — the `.tar.sha256` giving an integrity hash for the `.tar`, and `.tar.csv`
apparently an index of the tar's own contents (not probed further, no claim on its schema).
`last-modified: Wed, 13 Mar 2024` — unchanged since the 2024 CAP wind-down, confirming this is
a frozen archive, not a live-updating service.

## What this means for an agent

CAP's public identity ("the Caselaw Access Project has a REST API") is now stale training
data: `api.case.law` is a dead host that 301s to a docs page, and any agent treating a 301
there as "moved, follow and retry the query" will land on an HTML docs page, not JSON. The
living access path is bulk-download HTML directory pages at `static.case.law`, with no machine
manifest format offered at the paths probed here — an agent needs to parse the `<a href>`
table itself or already know the reporter-abbreviation and volume-number scheme to construct
download URLs.

How observed: 2026-10-05, 06:26Z UTC, curl 8 default User-Agent.
