Create Brand Kit
Create a brand kit — from a URL (extraction) or from direct fields (manual).
Pass url to run server-side extraction of brand info from a website,
OR pass the manual token fields (colors / fonts / logo_file_ids
with a name) to build a kit from what you already hold — the same write
the web app’s manual onboarding performs, for brands without a website.
Those two are mutually exclusive, enforced by the request schema.
name is NOT exclusive with url: send both to extract the brand and
title the kit with the name you supply. The extracted company_name is
left as extracted — naming a kit is not asserting what the company is
called. At least one of url or name is required.
Honors idempotency_key through the shared pipeline (a keyed retry
replays the stored result instead of minting a duplicate kit). A stored
result whose kit was DELETED since does not replay: the stale record is
invalidated and the create re-executes fresh (loud
stale_replay_invalidated marker). Brand create is NOT metered on
either path — no billing runs here — so the response carries the
zero-credit deterministic usage receipt.

Headers
Calendar-dated API version pin. New integrations should pin 2026-05-01 to opt into the newest response shapes. For back-compat the server also accepts requests with no header and resolves them to the current default (today: 2026-04-12); that default advances on each sunset date. Any unsupported value returns 400 unsupported_version.

Body
Request body for POST /v1/brand-kits — two creation paths.
Extraction (url): server-side extraction of colors, fonts, and logos
from a live website. Manual (name + optional colors / fonts /
logo_file_ids): build the kit from directly-supplied fields — for brands
with no website, or when the caller already holds the ground truth.
url is mutually exclusive with the manual TOKEN fields (colors /
fonts / logo_file_ids), which would assert a second source of truth for
fields the site already answers. name is NOT exclusive with it: passing both
extracts the brand and titles the kit with the supplied name (ENG-5415). At
least one of url or name must be provided.
Company website URL or domain (e.g. 'stripe.com') to extract brand data from. Mutually exclusive with the manual TOKEN fields (colors / fonts / logo_file_ids). name may accompany it: it titles the kit. The extracted company_name is left as extracted — naming a kit is not asserting the company's name.
Display name for the kit. On the MANUAL path it is also stored as the kit's company_name. Required there, and OPTIONAL alongside url, where it titles the kit only — extraction keeps ownership of company_name (ENG-5415).
1 - 255Manual path only: initial palette as an array of {color, label?, mode?, gradient?} objects (color is a hex string, e.g. '#0F172A'; mode is 'light' / 'dark' / 'any'). Same shape as the PATCH colors field.
Manual path only: initial fonts as an array of {family, label?, weight?} objects. Same shape as the PATCH fonts field. Each font's supported flag is derived server-side from the platform + team font catalogs; a caller-supplied value is ignored.
Manual path only: file_ IDs (from POST /v1/uploads) to attach as logos. Files must be images (image/*). Equivalent to calling addBrandKitImage with role='logo' for each after create, but atomic with the create itself.
20Prefixed file_ wire ID (Crockford base32 body) — the canonical, recommended form. For back-compat, a bare UUID string is also accepted in both path parameters and JSON request bodies (older integrations that stored raw UUIDs keep working), as is the prefix over a UUID body (file_00000000-0000-4000-8000-000000000000). All three are permanent, supported inputs; only the canonical form is ever emitted.
^file_[0-9A-HJKMNP-TV-Za-hjkmnp-tv-z]{26}$A retried create with the same key replays the stored result (replayed: true) instead of creating a second brand kit. Same-key reuse with a different payload is a 409 idempotency_conflict.
