Dapper
Dapper was an advertising-technology and web-data company founded in 2006 by Jonathan Aizen and Eran Shir, seed-funded by Accel. It ran two surfaces: Dapper Ads, an intent-driven dynamic-ad product that pulled live product and inventory data from an advertiser's own site into targeted creative without IT integration; and open.dapper.net (the "Dapp Factory" / Dapper: The Data Mapper), a hosted tool that turned any web page into structured feeds, web services and widgets — XML, RSS, JSON, YAML, CSV, iCalendar, Google Gadgets, Netvibes modules and image loops — effectively letting anyone "create an API for any site" before providers published their own. Dapper was acquired by Yahoo! in 2010 and both surfaces were shut down; dapper.net now resolves to Yahoo nameservers with no host, and open.dapper.net no longer resolves. There is no live API, developer portal, or documentation to enrich.
Dapper is tracked in the API Evangelist network. This page is the human-readable profile that sits on top of the machine-readable index we maintain at apis.io.
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. The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.

Dapper is in the network as a tracked entity. We haven't yet indexed a public API surface for it — when one is published, the artifacts, score, and agent-readiness read will appear here automatically. The source repository is where that profile is built.

This is an independent, third-party profile of Dapper, 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.
