Adyen: what its llms.txt contains
Measured on 2026-08-03: 600.4 KB, 4 sections, 2609 links. How that compares with the other 112 files we track, and what it implies.
Last updated:
The file
Adyen publishes an llms.txt at
https://adyen.com/llms.txt.
That URL redirects to https://www.adyen.com/llms.txt, which is where the file is actually
served. Worth knowing if you fetch it programmatically: a client that does not follow
redirects gets nothing.
The file declares itself as Adyen - Engineered for ambition in its H1, and the host is categorised here as fintech. It was last fetched and parsed on 2026-08-03.
Measured structure
| Measure | Adyen | Corpus median | Percentile |

| Size | 600.4 KB | 14.0 KB | 99th |
| H2 sections | 4 | 7 | 35th |
| Links | 2609 | 76 | 98th |
| Blockquote summary | Present | 90 of 113 have one | n/a |
Percentiles are against the 113 files in this directory, not against the web. That population is deliberately weighted toward documentation platforms and developer tools, which is where the convention started, so treat it as a peer group rather than a norm.
Observations
- 2609 links is closer to a sitemap than to a curated index. The convention exists so a model can skip crawling everything; a list this long hands the selection problem straight back to it.
- At 600.4 KB this is large enough that a client with a modest context budget may truncate it. Sites in that position usually split the map from the content and put the bulk in llms-full.txt.

How this was measured
Our checker fetches /llms.txt for every host in the directory, follows redirects, confirms
the response is Markdown rather than an HTML error page, and parses it with the same parser that powers
our validator. Sizes are of the served body, sections are H2 headings,
and links are Markdown links anywhere in the file. The run behind this page completed on 2026-08-03.
