Personally, I don’t like the Fujisaki-style curves. They look flashy, but they are not particularly clear to read, I think, and htey have loads of meaningless information. What matters is where the accent is placed, and what is the relative height of each mora.
In the (academic) literature, accents are not normally marked that way. I’ve often seen them marked in ways more like these:
As you can see, the one on the right is simpler, and has the only bit of information that is essential: the location of the fall, or its absence (I’ve seen this styled in web pages with spans and borders).
As for the source of that data, I think scraping OJAD, or getting the data manually, would be the easiest. I don’t know of any other reliable intonation dictionaries online. I have a paper one, but it doesn’t have compounds, and the API is horrid…
