Sinclair, Inc.
Sinclair, Inc. (Nasdaq: SBGI), formerly Sinclair Broadcast Group, is a diversified media company and one of the largest U.S. local television broadcasters. The company operates 177-185+ TV stations across roughly 79-86 markets affiliated with all major broadcast networks (Fox, NBC, CBS, ABC, MyNetworkTV, The CW), owns Tennis Channel, holds a stake in YES Network, and runs digital multicast networks Comet, Charge!, Roar, and The Nest. Sinclair Ventures houses the company's non-broadcast operations, including ad/martech units (AMP, Drive Auto, Free State, Digital Remedy/Compulse) and broadcast technology subsidiaries (Dielectric, ONE Media Technologies, Bitpath, CAST.ERA, Broadspan Wireless). In 2019 Sinclair acquired the Fox Sports regional sports networks for ~$9.6 billion through a Diamond Sports Group joint venture; Diamond was rebranded Bally Sports in 2021, filed Chapter 11 in March 2023, exited bankruptcy in January 2025 as Main Street Sports Group, rebranded again as FanDuel Sports Network, and is winding down operations in mid-2026. Sinclair runs no developer program and publishes no API documentation, but its corporate site at sbgi.net serves a live, public, unauthenticated WordPress REST API whose first-party sbg/v1 namespace publishes the company's full television station footprint — 197 primary stations and 365 digital subchannels across 87 Nielsen DMAs, with network affiliation, market rank and O&O/JSA/LMA/MSA ownership status attached to every call sign — alongside 1,753 press releases and the regional sports network territories.
Limited machine-readable signal and partial portal coverage — documentation a human can read, but little a machine or agent can consume without scraping.
API Evangelist profiles Sinclair, Inc. the way a machine reads it — 39 machine-readable artifacts across 2 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 — Sinclair, Inc. scores 36.2/100 (thin), with a separate agent-readiness read of 29/100 (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.

APIs 8
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.

Open Collections 1
Open, tool-agnostic collections carry the same runnable value as Postman without locking you to one client — the portable, forkable form of the same exercise.
Open, tool-agnostic API collections (OpenAPI-derived and Bruno).
Sinclair Corporate Content API
OPEN COLLECTIONPricing Plans 1
Pricing is part of the interface. Machine-readable plans tell you what a tier costs and includes before you commit — one of the things the Kin Score reads for access clarity — renamed from commercial clarity in rubric 0.12, because a free statutory interface has access terms and no commercial ones.
Published pricing tiers and plan structures.
Rate Limits 1
Rate limits are the difference between a demo that works and a production integration that doesn't fall over. Publishing them is an operational-transparency signal — and a hard requirement for any agent that plans its own throughput.
Documented rate limits and quota policies.

This is an independent, third-party profile of Sinclair, Inc., 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.
