Oooh Can you elaborate a bit how the gazette is publishing them? Like what format did you have to parse. And how many documents were there in total? I tried doing the same for German laws 1-2 years ago but LLMs weren't smart enough yet. And the costs would've been at least a couple of thousand €.

Ed: Nevermind, I missed the "BOE (Spain's official gazette) consolidated legislation API" part. Sending jealous greetings from Germany. We just have a bunch of PDFs in Germany. And the private entity that has been publishing them for decades even claims copyright on them!
