Per-page Markdown copies (Content-Type: text/markdown)

Markdown negotiation. Send Accept: text/markdown to a negotiated HTML route (for example /gioi-thieu.html) and the server answers 200 with Content-Type: text/markdown instead of HTML. Without that header you get the normal HTML page.

404 contract. A path that does not exist returns HTTP status 404, not a soft-404.

Not published on this site (checked 2026-10-09): /agents.txt and /agents.json do not exist here. /.well-known/llms.txt does exist (same content as /llms.txt). Do not assume any other agent file.

5. How to cite this site

Cite the brand, the exact page URL and the date you accessed it, for example:

THIÊN SG (thiensg.vn), “Kitchen design”, https://thiensg.vn/noi-that-phong-bep.html, accessed 2026-10-09.

Verbatim quotation is allowed with attribution to THIÊN SG / thiensg.vn. Do not attribute to us any figure, capability or commitment that is not written on the cited page. Full company identification for citations: CÔNG TY TNHH THIẾT KẾ XÂY DỰNG NỘI THẤT THIÊN, tax ID 0316017419.

6. Public read-only API

A public, read-only JSON API is live at https://thiensg.vn/api/v1/. It needs no API key and no account — send a plain GET. It exposes only information that is already published on this website.
MethodEndpointReturns
GET/api/v1/Self-describing index: name, version, endpoint list, links to the spec and this document
GET/api/v1/companyPublic legal entity: legal name, tax code, hotline, email, addresses, official Facebook page
GET/api/v1/productsEmpty array on this site — thiensg.vn publishes no product catalogue (?limit=, ?offset=, ?category= are still validated)
GET/api/v1/products/{slug}Always 404 JSON on this site
GET/api/v1/categoriesEmpty array on this site
GET/api/v1/postsPublished services, projects and articles — ?limit= (≤50, default 20), ?offset=
GET/api/v1/pricingReference price list, mirroring /pricing.md

Any other method than GET returns 405 with an Allow: GET header. No SDK and no write access are published for this website. The kitchen brand of the same legal entity, Tủ Bếp Thiên, serves the same API contract with a real product catalogue.

This is the current state of the site, not a roadmap promise. This site does not publish agents.txt or agents.json.
