Lily AI

Lily AI, Inc. is a retail product-intelligence company whose platform, Lily Max, enriches e-commerce product catalogs so that products are legible to advertising platforms, search engines, onsite search, and AI shopping agents. Agents identify gaps in a retailer's product data, generate consumer-centric attributes and copy, run controlled tests against a holdout, and deploy the winning enrichments across Google Merchant Center feeds, Meta Commerce Manager catalogs, AI discovery and agentic commerce surfaces, and onsite PDP, search, and faceting. Lily AI sells to enterprise retailers, brands, and agencies and positions itself as a layer over the existing commerce stack rather than a replacement for a PIM or feed manager. The company raised a $25M Series B with participation from Canaan Partners, Conductive Ventures, Sorenson Ventures, and NEA. Lily AI operates no developer program: there is no developer portal, no published API reference, no SDK, no GitHub organization, and no self-service credential path, and the platform is sold and onboarded through enterprise sales. It does, however, publicly serve the OpenAPI 3.0.0 contract for the LilyApp middleware that backs its customer application at app.lily.ai — 63 paths and 100 operations behind an Azure AD B2C bearer JWT, with a public Swagger UI. That contract is captured here as the company's only machine-readable API surface.

Lily AI publishes 1 API on the APIs.io network: LilyApp Middleware API. Tagged areas include Company, Retail, E-Commerce, Artificial Intelligence, and Product Data.

Lily AI’s developer surface includes authentication, engineering blog, pricing, signup flow, support, and 17 more developer resources.

  description: The middleware API behind Lily AI's customer application at app.lily.ai. Publicly served with a Swagger UI
    at /api and an OpenAPI 3.0.0 contract at /api-json (63 paths, 100 operations, 41 schemas), covering retailer/subsidiary
    configuration, product search over Lily's consumer-centric attribute tags and synonyms, product analytics and search-term
    trends, AI product-copy generation and batch review, outbound partner integration configuration, and a set of pass-through
    proxies to Lily's internal product-intelligence, connector, config, TCE and enrichment-platform services. Calls require
    a bearer JWT issued by Lily AI's Azure AD B2C tenant; Lily AI publishes no developer documentation and offers no self-service
    way to obtain one.

  note: 'Contract discovery (STEP 0b) beat the previous "no public API surface" finding. The app.lily.ai production bundle
    names https://lilyapp-api-prd.pub.lilyai.net as its API base; that host serves a public Swagger UI at /api and an OpenAPI
    3.0.0 contract at /api-json, harvested verbatim. Ownership confirmed per STEP 0c: info.title "LilyApp API - Nest Based
    Application", description "Lily App Middleware", servers[] empty (no contradicting host), lilyai.net registered to the
    same AWS-hosted estate, docker image lilyaidocker/lilyapp-api, and the contract''s resources (subsidiary/brand config,
    Lily product-attribute tags, product-copy generation, partner feed integration) are Lily AI''s own product.'
