Source: https://agentreadyhtml.com/vendors/zuplo/ Site: Agent Ready HTML Last reviewed: 2026-11-05 # Zuplo: vendor profile In short Zuplo's Developer Portal, built on Zudoku, is prerendered and writes a .md copy per page. It answers Accept: text/markdown with Vary: Accept, and llms.txt stays off until a setting turns it on. A portal page returned 4,256 bytes of markdown on 2026-11-05. The Free plan covers 100K requests a month. ## At a glance **standards.txt** zuplo ```text llms-txt = partial markdown-negotiation = supports markdown-twin = supports initial-html = supports real-404 = no statement vary-accept = supports ``` 4 supports, 1 partial or announced, 1 no statement. **Zuplo** Docs platform API gateway vendor whose Developer Portal, built on the Zudoku framework, is statically prerendered by default, writes a .md copy per page, answers Accept: text/markdown with Vary: Accept, and can emit llms.txt and llms-full.txt when switched on.
