# Nápověda FAPI

> Czech customer guides for selling, invoicing, payments and integrations with FAPI.

AI agents: prefer the published Markdown/MDX sources over crawling HTML. They contain the article text and metadata without navigation, tracking scripts or page layout.
If you already have an article URL, send Accept: text/markdown to that URL to receive its published MDX directly in one response. The homepage returns this guide for the same Accept header. No catalogue download is needed for a known article.
Otherwise search the compact title index, then fetch only the relevant MDX files. Avoid crawling every HTML page or downloading images and videos for text research. Use gzip transport, for example curl --compressed, to reduce transferred bytes.
MDX includes YAML frontmatter and may contain Video and Callout components. Cite the public article URL from its metadata and resolve relative links against that public URL.
The index and MDX files belong to the same published release as the HTML. Cache responses and revalidate with ETag or Last-Modified on later visits.

For bulk or repeated research, download the public content repository once and search locally. Use a sparse checkout to avoid downloading image and video assets:

```sh
git clone --depth 1 --filter=blob:none --sparse https://github.com/fapi-cz/help-content.git fapi-help-content
git -C fapi-help-content sparse-checkout set content
git -C fapi-help-content fetch --depth 1 origin 7509cf795304b1f6e03e9aa211e89677e2742fba
git -C fapi-help-content checkout --detach 7509cf795304b1f6e03e9aa211e89677e2742fba
```
