Stop crawling my HTML – use the API

The API may be equivalent, but it is still conceptually secondary. If it went stale, readers would still see the site, and it makes sense for a scraper to follow what readers can see (or alternately to consume both, and mine both).

The author might be right to be annoyed with the scrapers for many other reasons, but I don't think this is one of them.

Plus, the feeds might not get you the same content. When I used RSS more heavily some of my favorite sites only posted summaries in their feeds, so I had to read the HTML pages anyway. How would an scraper know whether that's the case?

The real problem is the the explosion of scrapers that ignore robots.txt has put a lot of burden on all sites, regardless of APIs.

I guess that would only work if the scraped site was used in a prompting context, but not if it was used for training, no?

Also if I'm ingesting something from an API it means I write code specific to that API to ingest it (god forbid I have to get an API token, although in the authors case it doesn't sound like it), where as with HTML, it's often a matter of go to this selector, figure out what are the land mark headings, the body copy and what is noise. Which is easier to generalise, if I'm consuming content from many sources.

I can only imagine it's no easier for a crawler, they're probably crawling thousands of sites and this guys website is a pitstop. Maybe an LLVM can figure out how to generalise it, but surely a crawler has limited the role of the AI to reading output and deciding which links to explore next. IDK maybe it is trivial and costless, but the fact it's not already being done shows it probably requires time and resources to setup and it might be cheaper to continue to interpret the imperfect HTML.

The reason HTML is more interesting is because the Ai can interpret the markup and formatting, the layout, the visual representation and relations of the information

Presentation matters when conveying information to both humans and agents/ai

Plaintext and JSON are just not going to cut it.

Now if OP really wants to do something about it, give scrapers a markdown option, but then scrapers are going to optimize for the average, so if everyone is just doing HTML, and the HTML analysis is good enough, offered alternatives are likely to be passed on

The mosr remarkable case I ever saw was trying to parse Wikipedia markup from the data dumps that they quit publishing and struggling to get better than 98% accuracy and then writing a close to perfect HTML-based parser in minutes starting with the Flick parser.

Almost always an APi is not a gift but rather a take-away.

That said, when I wrote Blackbird, my first web crawler, in 1998, I was already obsessive about politeness and efficiency from a “low observability” perspective as much as being the right thing to do.

It seemed like this was a big elephant in the room - what's the point in spending ages putting API's carefully on your website if all the AI bots just ignore them anyway? There are times when you want your open data to be accessible to AI but they never really got into a discussion about good ways to actually do that.

You introduce a whole host of potential problems, assuming those are all solved, you then have a new 'standard' that you need to hope everyone adopts. Sure WP might have a plugin to make it easy, but most people wouldn't even know this plugin exists.

Now guess whether the AI is more likely trained on parsing and interacting with your custom schema or plain HTML.

These CEOs got rich by pushing a product built on using other people's content without permission, including a massive dump of pirated textbooks. Probably sci-hib content too.

It's laughably naive to think these companies will suddenly develop ethics and start being good netizens and adhere to an opt-in "robots.txt"-alike.

Morality is for the poor.

The API-first dream is nice in theory, BUT in practice most "public" APIs are behind paywalls or rate limits, and sometimes the API quietly omits the very data you're after. When that happens, you're flying blind if you refuse to look at the HTML...

Scraping isn't some moral failing... it's often the only way to see what real users see. ALSO, making your HTML semantic and accessible benefits humans and machines alike. It's weird to shame people for using the only reliable interface you provide.

I think the future is some kind of permission economy where trusted agents can fetch data without breaking TOS... Until that exists, complaining about scrapers while having no stable API seems like yelling at the weather.

Shipping serialized data and defining templates for rendering data to the page is a really clever solution, and adding support for JSON in addition to XML eases many of the common complaints.
