SNAC Archives runs on your own machine — the client starts it, so there is no endpoint to ping. 441 installs a week from pypi. Last commit 6 Oct 2026.
Find which archive holds the papers: SNAC's index of archival collections, plus ArchiveGrid links.
Today is the operative word: we check SNAC Archives every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

This one needs environment variables set before it will start:
SNAC_API_URL (The SNAC REST API endpoint.), SNAC_CACHE_DIR (Directory for the on-disk response cache.), SNAC_TIMEOUT (HTTP timeout in seconds. Holdings lists get 120 s of their own.), SNAC_CONTACT (An email address or URL appended to the User-Agent, so SNAC can reach whoever runs the server.).
The author declared them in the registry entry; get the values from the project itself.
