Murmur Technologies INC
Murmur Technologies INC (Murmur) is a Chicago, Illinois out-of-home advertising technology company operating a mobile digital billboard platform. It mounts smart LCD screens on car-tops and pedestrian backpacks to display geo-targeted ads on city streets, using sensors, computer vision, and location data to segment audiences by demographics, location, and behavior, measure ad performance in real time, and retarget viewers across other channels such as Facebook and Google. The company was surfaced as a portfolio company of 500 Global and added to the API Evangelist network as a lead for enrichment. As of this enrichment pass its public web hosts (murmurcars.com / murmurads.com) do not resolve to a live web server and the operation appears dormant; it exposes no public API, developer portal, SDKs, or documentation.
Index entry only — little beyond a description and a link, and nothing machine-readable enough for an agent to act on without a human reading the site first.
API Evangelist profiles Murmur Technologies INC the way a machine reads it — 1 machine-readable artifact, 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 — Murmur Technologies INC scores 6.8/100 (minimal), with a separate agent-readiness read of 0/100 (human only). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
