# Baseline (baseline.zip) > Professional foundry typefaces for websites — faces you cannot get on Google Fonts — > with trial licensing built in. Agents may freely apply trial fonts during development; > a human must accept the trial agreement once per project, and fonts must be licensed > before the site ships publicly. ## Integrate Baseline into a website project (4 steps) 1. Inject the floating bar into DEV builds only: (Next.js: in the root layout behind process.env.NODE_ENV === 'development'.) The bar shows the trial agreement on first open — the HUMAN developer accepts it and receives a project key (bsln_...). Do not fabricate or auto-accept this. 2. Store the key in baseline.json at the repo root: { "projectKey": "bsln_...", "fonts": [] } 3. Apply a font (Google Fonts pattern; multiple families with | ): then e.g. h1 { font-family: 'Teodor', serif; } 4. Search the catalog: GET https://baseline.zip/api/fonts?q=QUERY&category=serif|sans-serif|display|script|mono GET https://baseline.zip/api/project/PROJECT_KEY → fonts in use + license status POST https://baseline.zip/api/checkout → { projectKey, familyId, licensee: "self" | "client" } ("client" returns a payUrl to give the client; license activates on payment.) ## Rules for agents - Trial fonts are for development/preview only. Tell the user which fonts are unlicensed before any production deploy (GET /api/project/KEY → unlicensedCount). - Never remove or bypass the licensing notices. - Every served font file is fingerprinted to its project registration. ## Catalog (18 families) - abc-synt — ABC Synt (display, Dinamo): An experimental display face with synthetic, machine-drawn energy. For brands that want to feel engineered and strange. - place — Place (display, Commercial Type): A confident poster display face built for scale. Commands attention at headline sizes. - season-mix — Season Mix (display, Displaay): A playful display family that mixes constructions for an eclectic, collaged feel. Best where personality matters most. - abc-diatype-mono — ABC Diatype Mono (mono, Dinamo): The monospaced counterpart to ABC Diatype. Technical without being sterile — great for code, data, and technical brands. - beltram-mono — Beltram Mono (mono, Domicile Foundry): A characterful monospace with warmth and personality — proof that fixed-width doesn’t have to feel mechanical. - abc-diatype — ABC Diatype (sans-serif, Dinamo): A workhorse neo-grotesque with Swiss precision and a slightly warm, contemporary voice. Excellent for interfaces, branding, and long text at small sizes. - abc-whyte — ABC Whyte (sans-serif, Dinamo): A grotesque with brutalist edges and idiosyncratic details. More opinionated than Diatype; great for punchy headlines and editorial identities. - haffer — Haffer (sans-serif, Displaay): A friendly grotesque-geometric hybrid with unexpected quirks in the details. Approachable without being childish. - macan-stencil — Macan Stencil (sans-serif, Tightype): A contemporary stencil sans with clean cuts and confident geometry. Distinctive in headlines and packaging. - neue-haas-grotesk-display-pro — Neue Haas Grotesk Display Pro (sans-serif, Monotype (Linotype)): The original Helvetica, restored. Christian Schwartz’s digitization returns the warmth and detail lost in decades of adaptation. The definitive neutral sans. - twk-lausanne — TWK Lausanne (sans-serif, TYPE.WELTKERN): A refined Swiss grotesk beloved by editorial and fashion brands. Understated, precise, and elegant at every size. - jimmy-script — Jimmy Script (script, Independent): A casual handwritten script with natural rhythm. Adds a human touch to accents, labels, and signatures. - antique-no-6 — Antique No 6 (serif, Commercial Type): A sturdy serif in the 19th-century antique tradition — dark, grounded, and full of conviction in headlines and text alike. - caslon-ionic — Caslon Ionic (serif, Commercial Type): A Caslon in the Ionic newspaper tradition: slab-adjacent serifs, high legibility, and Victorian-era character built for modern use. - morion — Morion (serif, The Designers Foundry): An angular display serif with blade-like details. Dramatic at large sizes; brings tension and edge to headlines. - orleans — Orleans (serif, Commercial Type): An elegant editorial serif with refined contrast and a literary voice. At home in magazines, books, and cultural identities. - signifier — Signifier (serif, Klim Type Foundry): A brutalist response to 17th-century Fell types: historical forms rendered with digitally sharp edges. Striking in display, surprisingly readable in text. - teodor — Teodor (serif, Displaay): A sharp contemporary serif with wedge-like terminals. Cool, fashionable, and precise — a favorite for modern editorial design.
