# LAKA Funnel Grammar > A declarative marketing and funnel grammar built on the LAKA model: an eight-variable positioning grid with four change levels, a six-stage funnel grammar, a page-section grammar with copy rules, an email nurture grammar, a worked case study, and a machine-checkable outline schema with a public validator. Version 1.0.0, reviewed 2026-09-03. 8 positioning variables × 4 change levels (32 grid cells), 6 funnel stages, 11 section contracts, 21 copy rules, 6 email archetypes, 8 platform entities, 9 sources, 5 case-study documents. Boundaries: This site is a marketing methodology and reference, not a performance guarantee, an advertising service, legal or financial advice, or evidence of results for any business. The HouseSmart material is a worked case study demonstrating the method. The grammar constrains structure and honesty; it cannot substitute for a real offer that delivers what it promises. ## API Base URL: https://marketing.bowtiekreative.com OpenAPI: https://marketing.bowtiekreative.com/v1/openapi.json Index: https://marketing.bowtiekreative.com/v1 Read: - https://marketing.bowtiekreative.com/v1 — This index - https://marketing.bowtiekreative.com/v1/health — Liveness and corpus counts - https://marketing.bowtiekreative.com/v1/openapi.json — OpenAPI 3.1 description of this API - https://marketing.bowtiekreative.com/v1/manifest — Package manifest and inventory - https://marketing.bowtiekreative.com/v1/grid — The LAKA marketing grid — 8 variables × 4 change levels - https://marketing.bowtiekreative.com/v1/stages — The six funnel stages - https://marketing.bowtiekreative.com/v1/stages/{id} — One stage, e.g. homepage, with rules and required sections - https://marketing.bowtiekreative.com/v1/sections — The page-section grammar - https://marketing.bowtiekreative.com/v1/sections/{id} — One section type, e.g. hero, with its element contract - https://marketing.bowtiekreative.com/v1/rules — The copy rules — filter by category, severity or q - https://marketing.bowtiekreative.com/v1/rules/{id} — One copy rule, e.g. MG-CTA-001 - https://marketing.bowtiekreative.com/v1/emails — The email nurture grammar and archetypes - https://marketing.bowtiekreative.com/v1/platform — The execution-platform domain model - https://marketing.bowtiekreative.com/v1/example — The HouseSmart worked case study, structured - https://marketing.bowtiekreative.com/v1/example-outline — A valid outline of the case-study homepage - https://marketing.bowtiekreative.com/v1/schema — The JSON Schema for a funnel-page outline - https://marketing.bowtiekreative.com/v1/sources — The source register and boundaries - https://marketing.bowtiekreative.com/v1/docs — The case-study documents - https://marketing.bowtiekreative.com/v1/docs/{slug} — One document, as markdown Validate: - POST https://marketing.bowtiekreative.com/v1/validate — check a funnel-page outline JSON against the published schema and the stage/section grammar.

Write one grid cell per variable before any copy; the deepest change level claimed sets the funnel's education burden. Every page carries one promise, every CTA is verb-first, the problem precedes the mechanism, and urgency comes only from real irreversibility. The HouseSmart material is a worked case study demonstrating the method — no market results are claimed for it.
