If the object is sent, name, email and phone are required. Without the object, the generator invents the name and contacts. All fields are strings.

• Format — #rrggbb or a short #rgb, case-insensitive, surrounding spaces are trimmed. #1E6FD9 and #1e6fd9 — the same color, #16d reads as #1166dd.
• An empty string or no field — the palette is picked for the niche.
• Anything else — rgb(), color names, a code without # — error 400 invalid_request.
• The color isn't copied one-to-one: each site gets its own close shade, so one team's sites don't repeat each other.
• On Basic the field is accepted but not applied — warning brand_color_not_in_tier.

• A Latin-script domain: letters, digits and hyphens, at least one dot. Cyrillic domains — in punycode: xn--…
• The scheme is optional: http:// and https:// are accepted; site links will always use https.
• www is kept — you decide which host is canonical. A path is allowed for a site in a subfolder.
• A trailing slash, parameters ?… and an anchor #… are dropped.
• Not allowed: spaces, a port, an IP address, credentials in the address (user@) — error 400 invalid_request.
• Without a domain the site is built without sitemap.xml, canonical, og:url and hreflang: they need a full address.

• Codes — same as in language: two-letter lowercase ISO 639-1 codes from the supported list. Regional variants (en-GB, pt-BR) are not accepted.
• The main language sits at the site root and is marked as x-default. Additional languages go into subfolders /en/, /de/ in array order.
• Duplicates and the main language inside extraLanguages are skipped and don't count toward the limit.
• Tier limit — Premium 2, Elite 9 additional, Basic 0. Extra languages are dropped from the end of the array and the order price doesn't change — warning language_limit.
• An unsupported code in language or extraLanguages — error 400 invalid_request.
• If the niche can't be done in one of the languages (for example, VPN in Russian) — 422 niche_language_refused, and no order is created. Remove that language and try again.

• An ISO 3166-1 code, case-insensitive: mx and MX are the same country.
• Supported: US GB CA AU IE NZ DE AT CH ES MX CO CL FR BE RU KZ IT PT BR NL PL CZ RO SE DK NO.
• The country does not change the site's language — that is set by language. An English site for a German company is "language": "en", "country": "DE": prices in euros, phone +49, imprint in English.
• Missing, or a code not on the list, is an error 400 invalid_request with the field country, no credits are charged.

• html (default) — a static site: any hosting, Netlify, GitHub Pages.
• php — the same pages plus a request handler: forms send requests to companyInfo.email. Needs hosting with PHP 7.0 or newer where sending mail works (mail()).
• Without companyInfo.email the site gets demo contacts and there is no email for requests: forms accept none until you write an address at the top of the PHP file.
• The price does not depend on the format. Any other value is an error 400 invalid_request.
