title: fatcat auth Releases API
version: 0.5.0
description: 'Fatcat is a scalable, versioned, API-oriented catalog of bibliographic
entities and file metadata.
<!-- STARTLONGDESCRIPTION -->
These API reference documents, along with client software libraries, are
generated automatically from an OpenAPI 2.0 ("Swagger") definition file.
## Introduction
A higher-level introduction to the API, as well as a description of the
fatcat data model, are available in ["The Fatcat Guide"](https://guide.fatcat.wiki/).
The guide also includes a [Cookbook](https://guide.fatcat.wiki/cookbook.html)
section demonstrating end-to-end tasks like creating entities as part of
editgroups, or safely merging duplicate entities.
### Expectations and Best Practices
A test/staging QA API instance of fatcat is available at
<https://api.qa.fatcat.wiki/v0>. The database backing this instance is
separate from the production interface, and is periodically rebuilt from
snapshots of the full production database, meaning that edits on the QA
server will *NOT* persist, and that semantics like the changelog index
monotonically increasing *MAY* be broken. Developers are expexcted to test
their scripts and tools against the QA instance before running against
production.
NOTE: as of Spring 2021, the QA server is temporarily unavailable.
Fatcat is made available as a gratis (no cost) and libre (freedom
preserving) service to the public, with limited funding and resources. We
welcome new and unforeseen uses and contributions, but may need to impose
restrictions (like rate-limits) to keep the service functional for other
users, and in extreme cases reserve the option to block accounts and IP
ranges if necessary to keep the service operational.
The Internet Archive owns and operates it''s own server equipment and data
centers, and operations are optimized for low-cost, not high-availability.
Users and partners should expect some downtime on the fatcat API, on the
order of hours a month.
Periodic metadata exports are available for batch processing, and database
snapshots can be used to create locally-hosted mirrors of the service for
more intensive and reliable querying.
### Other Nitty Gritties
Cross-origin requests are allowed for the API service, to enable third
parties to build in-browser applications.
A metadata search service is available at <https://search.fatcat.wiki>.
The API is currently the raw elasticsearch API, with only GET (read)
requests allowed. This public service is experimental and may be removed or
limited in the future.
## Authentication
The API allows basic read-only "GET" HTTP requests with no authentication.
Proposing changes to the metadata, or other mutating requests ("PUT",
"POST", "DELETE") all require authentication, and some operations require
additional account permissions.
End-user account creation and login happens through the web interface. From
a logged-in editor profile page, you can generate a API token. Tokens are
"macaroons", similar to JWT tokens, and are used for all API
authentication. The web interface includes macaroons in browser cookies and
passes them through to the API to authenticate editor actions.
