Sources and Verification Notes

Research date: 2026-09-30.

Official LabArchives help pages were read through the web tool. The shared API notebook was read with fresh parallel-cli extract requests and by navigating its public tree in Chrome, because basic extraction returned an empty shell and one container-page extraction redirected to login. Browser reading resolved that gap without authentication. PyPI and GitHub public metadata were checked for optional community clients. No authenticated API requests, remote writes, or product-integration transfers were performed.

Official API sources

ELN overview and regional API hosts

https://mynotebook.labarchives.com/share/LabArchives%20API/NS4yfDI3LzQvVHJlZU5vZGUvMTF8MTMuMg

• Page revision: 2025-11-03
• Describes the ELN API as REST-like.
• Lists API hosts for US/rest of world, Australia/New Zealand, UK, Europe outside the UK, and Canada.
• Requires HTTPS.
• States that many responses are XML and child-element order is not fixed.

Requirements and best practices

https://mynotebook.labarchives.com/share/LabArchives%20API/MTM2LjV8MjcvMTA1L1RyZWVOb2RlLzM2MzY3OTM2NjF8MzQ2LjU=

• Page revision: 2024-06-28
• Credentials are issued for a specific organization/vendor and purpose.
• Large batches must be serialized or staggered by at least one second.
• HTTP 4xx responses must not be automatically retried.
• Eligible retries must wait at least one second, back off, and stop at a bounded count/duration.
• expires should represent current epoch milliseconds, with server-clock adjustment, not a future expiry.

Call authentication

https://mynotebook.labarchives.com/share/LabArchives%20API/Ny44fDI3LzYvVHJlZU5vZGUvMTE1MzU5MTAyNXwxOS44

• Page revision: 2023-05-10
• Defines Base64(HMAC-SHA-512) over the concatenation of Access Key ID, method input, and expires, using the Access Password as the HMAC key.
• Documents akid, expires, and URI-encoded sig query parameters.
• The published dummy test vector is reproduced by scripts/entry_operations.py self-test.

API user login and UID

https://mynotebook.labarchives.com/share/LabArchives%20API/ODEuOXwyNy82My05My9UcmVlTm9kZS8yMjYyMTU0MTg3fDIwNy44OTk5OTk5OTk5OTk5OA==

• Page revision: 2023-03-03
• Documents the signed /api_user_login redirect, returned auth_code and email, and redemption through users::user_access_info.
• Defines the user-generated temporary password token alternative.
• States that UIDs are bound to the Access Key ID and persist until revoked.

ELN API class tree

https://mynotebook.labarchives.com/share/LabArchives%20API/MS4zfDI3LzEvVHJlZU5vZGUvODYxMDc1MjB8My4z

• Current tree includes entries, search tools, utilities, users, tree tools, notifications, notebooks, and site-license tools.
• Method pages, not names inferred from other clients, are the source of truth.

ELN entry response elements

https://mynotebook.labarchives.com/share/LabArchives%20API/NjguOXwyNy81My9UcmVlTm9kZS8xODUxMDkwNDk2fDE3NC45

• Documents common <entry> XML fields and optional entry/comment data.
• Distinguishes attachment metadata from retrieval of attachment bytes.

LA container file

https://mynotebook.labarchives.com/share/LabArchives%20API/Ni41fDI3LzUvVHJlZU5vZGUvNDQ3MDk3MTI0fDE2LjU=

• Original page revision shown as 2014-11-10; the public page also contained an example-file revision dated 2026-03-02 at research time.
• Defines an LA container as a ZIP with lamanifest.xml, an application file, preview file, and UTF-8 index file.
• This format is not the same thing as a notebook-backup response.

Inventory authentication

https://mynotebook.labarchives.com/share/LabArchives%20API/MTQ0LjN8MjcvMTExL1RyZWVOb2RlLzM5NjYzNjc4MjJ8MzY2LjI5OTk5OTk5OTk5OTk1

• Page revision: 2025-11-24
• Inventory uses the shared LabArchives authentication flow.
• Requires a new signature for each exact relative route.
• Lists X-LabArchives-UId, X-LabArchives-AKId, X-LabArchives-LabId, X-LabArchives-Signature, and X-LabArchives-Expires.
• Route parameters are included in the signature input; query parameters are excluded. The method-specific users/me exception omits the Lab ID header.

Inventory API v1 item creation

https://mynotebook.labarchives.com/share/LabArchives%20API/MTg4LjV8MjcvMTQ1L1RyZWVOb2RlLzEyOTcxODY5ODF8NDc4LjU=

• Page revision: 2026-04-02
• The public navigation labels the Inventory surface APIs (v1).
• Explicitly documents POST /public/v1/inventory and its JSON body fields.
• The navigation also exposes read/update item routes and sections for item types, orders, storage locations, and vendors.

Method-level audit

Opened every endpoint named by this skill through ELN API Classes or Inventory > APIs (v1) in the official notebook:

• entries/entry_info: GET, uid/eid, optional data/comment flags; XML.
• entries/entry_attachment: GET, uid/eid, raw application file and Content-Disposition, not an LA container ZIP.
• notebooks/notebook_backup: GET, owner uid/nbid, optional json and no_attachments; .7z archive. Internal archive schema remains access-gated.
• users/user_access_info: GET, login_or_email and authorization-code/token password, signed query; returns UID and auto-login permission in XML.
• users/user_info_via_id: GET with UID; honor auto-login permission and the documented restricted purpose of authenticated=true.
• utilities/epoch_time: GET with akid, no sig/expires; epoch milliseconds.
• utilities/api_base_urls: signed GET; XML region URL/description list. Its older example uses browser hosts, inconsistent with the newer API overview.
• Inventory GET /public/v1/users/me: lab discovery, no Lab ID needed; https://mynotebook.labarchives.com/share/LabArchives%20API/MTQ4LjIwMDAwMDAwMDAwMDAyfDI3LzExNC9UcmVlTm9kZS8zODc0Mjc0OTI5fDM3Ni4y
• Inventory GET /public/v1/inventory: JSON array, pageSize at most 1000, pageNumber, optional filters; out-of-stock items excluded by default. Page-number origin/default and stable ordering are not specified.
• Inventory GET /public/v1/inventory/{itemId}: one item JSON object, no query; https://mynotebook.labarchives.com/share/LabArchives%20API/MTg0LjZ8MjcvMTQyLTIyMC9UcmVlTm9kZS8zMzkzMTkwNjY5fDQ2OC41OTk5OTk5OTk5OTk5Nw==
• Inventory GET /public/v1/inventory/{itemId}/attachments: ZIP bytes.
• Inventory POST create and update: name and typeId marked required, HTTP 200 item detail; examples include comments that must be removed for valid JSON.

Inventory > Overview explicitly publishes https://iapi.labarchives.com, request Content-Type: application/json, JSON/ZIP response media types, and v1 version/deprecation policy. It does not provide a regional variant table. Navigate there from the official notebook linked above; navigation does not update its address bar, so the method titles identify the pages read.

Community Python client status

Community projects are not official LabArchives sources and are not installed by this skill.

mcmero/labarchives-py

https://github.com/mcmero/labarchives-py

GitHub metadata checked 2026-09-30:

• personal/community repository, not LabArchives-owned,
• last commit: 2022-08-10 (1b5b745baaf9),
• no tags,
• no GitHub releases,
• no official LabArchives endorsement found.

Conclusion: remove the old unpinned Git clone installation and do not recommend this wrapper by default.

nimh-dsst/labapi

• PyPI: https://pypi.org/project/labapi/
• Source: https://github.com/nimh-dsst/labapi
• Documentation: https://nimh-dsst.github.io/labapi/

Verified status on 2026-09-30 using project-owned PyPI/GitHub metadata:

• NIMH DSST community project, not LabArchives-owned;
• stable release 1.2.0, published 2026-08-20 on PyPI and GitHub;
• Python requirement >=3.10;
• current PyPI license_expression and GitHub license both identify MIT;
• no official LabArchives endorsement was identified in the reviewed vendor docs.

Metadata sources:

• https://pypi.org/pypi/labapi/json
• https://api.github.com/repos/nimh-dsst/labapi/releases
• https://api.github.com/repos/nimh-dsst/labapi/license

This review checked release metadata, not client execution or transitive behavior. Adoption remains a separate institution-reviewed choice. Pin the selected release and inspect its credential-loading behavior; the bundled standard-library tools do not import or require this client.

Claims not established by public official sources

The research did not establish:

• an Inventory regional base-URL table beyond the published iapi.labarchives.com,
• the Inventory list endpoint's page-number origin/default or stable ordering,
• a numeric requests-per-minute or burst quota,
• a generic LabArchives OAuth 2.0 authorization/token endpoint,
• an official LabArchives Python SDK,
• a blanket backward-compatibility guarantee for the legacy ELN API,
• universal attachment extensions, file-size limits, or archive formats,
• that every advertised product integration exposes a programmable API.

Obtain missing product-specific details from institution/vendor-provided API documentation or LabArchives support. Do not fill gaps from model memory or a community wrapper.
