Buzzer
Buzzer was a mobile live-sports streaming startup founded in 2020 by Bo Han, formerly director of live content at Twitter. Its consumer app, launched in 2021, sold micropayment access — as low as $0.99 to $1 — to short in-game moments of live sporting events, targeting Gen Z fans who would not buy a full cable or league subscription. Buzzer secured streaming rights covering the NBA, WNBA, NHL, PGA Tour and ATP Tour, and raised roughly $44 million in total, including a $20 million Series A in June 2021 co-led by Sapphire Sport and Canaan Partners alongside a large group of athlete and team-owner investors. On 19 May 2023 the company shut down the direct-to-consumer app and pivoted to a business-to-business model branded "Powered by Buzzer", announced as API licensing, custom development and consulting for leagues, teams and networks streaming direct to fans. That offering never reached public availability: Buzzer ceased all operations on 30 June 2023, citing "recent fundraising developments and market dynamics". No public developer portal, API documentation, specification, SDK or package was ever published. The buzzer.com domain no longer hosts the company and now redirects to an Atom.com domain-for-sale listing. Retained in the network as a historical record of a defunct company; not an active API provider.
Buzzer 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.
Buzzer 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 Buzzer, 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.
