@ardumont @vlorentz This one is quite simple but like pubdev we do not have access to coherent data to set a last_update. See https://hackage.haskell.org/packages/
To retrieve origins we can alternatively retrieve an index.tar.gz which list package names, related version and finally a cabal file with some metatata, but nothing date related and in this case the only benefit is to get some related versions.
Example for the package 4Blocks in index/4Blocks/0.1/4Blocks.cabal:
-- 4Blocks.cabal auto-generated by cabal init. For additional options, see
-- http://www.haskell.org/cabal/release/cabal-latest/doc/users-guide/authors.html#pkg-descr.
-- The name of the package.
Name: 4Blocks
Version: 0.1
Synopsis: A tetris-like game (works with GHC 6.8.3 and Gtk2hs 0.9.13)

There is an API that provides access to the lastUpload:
$ curl "https://hackage.haskell.org/packages/search" -H "Accept: application/json" -H "Content-Type: application/json" --data '{"page": 0, "sortColumn": "default", "sortDirection": "ascending", "searchQuery": "(deprecated:any)"}' -X POST | jq . | head -n 50 % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 100 23907 0 23806 100 101 40145 170 --:--:-- --:--:-- --:--:-- 40315 { "numberOfResults": 16711, "pageContents": [ { "description": "Haskell package for easy integration with the 2captcha API.", "downloads": 1, "lastUpload": "2021-09-09T05:13:30.343509948Z", "maintainers": [ { "display": "qwbarch", "uri": "/user/qwbarch" } ], "name": { "display": "2captcha", "uri": "/package/2captcha" }, "tags": [ { "display": "deprecated", "uri": "/packages/tag/deprecated" }, { "display": "library", "uri": "/packages/tag/library" }, { "display": "mit", "uri": "/packages/tag/mit" }, { "display": "network", "uri": "/packages/tag/network" } ], "votes": 1.5 }, { "description": "Examples of 3D graphics programming with OpenGL", "downloads": 8, "lastUpload": "2016-07-22T14:26:23.038905Z", "maintainers": [ { "display": "WolfgangJeltsch", "uri": "/user/WolfgangJeltsch" } ], "name": { "display": "3d-graphics-examples", "uri": "/package/3d-graphics-examples"
You can also use the same API for incremental listing by filtering on lastUpload in the search query.

I now understand why I do not experiment this endpoint in the first place. It is not documented as a POST (and it does not seems natural to use POST to get something that usually use GET with query params).
I've made an implementation this way but now I have to manage pagination. The endpoint returns only 50 entries and I did not find a way to bypass that (using pageSize has no effect).
Comment Actions
It is: https://hackage.haskell.org/api#search/browse%20backend
But since the Hackage's documentation is clearly spotty, I used Firefox's debugger to see what API the GUI used, that's how I found this endpoint.
Comment Actions
Change http api endpoint for search in order to retrieve a last_update
Switch from GET to POST to get results.
Lister is not a single page anymore, each page list 50 origins.
