Constructor.io
Constructor (Constructor.io) is an AI-powered ecommerce search and product discovery platform for online retailers. Its APIs cover autocomplete/autosuggest, keyword and natural-language search, image search, category browse, recommendations, quizzes, collections, offsite/email discovery, retail media (sponsored listings and display ads), an AI Shopping Agent and Product Insights Agent, plus a full catalog-management and configuration surface for items, variations, item groups, facets, searchabilities, synonyms, sort options, redirects and searchandising rules. Results are optimized against ecommerce KPIs (conversion, revenue per visit) using natural-language processing, behavioral re-ranking and per-user personalization, and are delivered through a REST API served from the ac.cnstrc.com family of hosts with first-party client libraries for JavaScript, Node.js, Python, Java, .NET, Ruby, Swift and Kotlin.
Real signal across most facets with visible, nameable gaps — the contract exists but is thin, or the portal is good while governance and commercial terms are absent.
API Evangelist profiles Constructor.io the way a machine reads it — 61 machine-readable artifacts across 34 APIs, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.
Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — Constructor.io scores 53.9/100 (developing), with a separate agent-readiness read of 28/100 (agent aware). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
Kin Score
This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance. Every facet and dimension name is a link: it opens that measurement's page on APIs.io, where the rating runs across the whole catalog — the exact checks that feed it, how every profiled provider distributes on it, and who is at the top of it.

How we profile Constructor.io
Each block below is one kind of artifact we hold for Constructor.io. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.
APIs 39
Each API is captured as its own OpenAPI definition — every operation, parameter, and response. This is the single most useful machine-readable description of what an API does, and it's what lets us score, lint, mock, and generate against it without asking the provider for anything.
Individual APIs this provider publishes, each with its own machine-readable definition.

This is an independent, third-party profile of Constructor.io, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.
The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.
Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
