PubMatic
PubMatic is a Redwood City, California-headquartered independent technology company (NASDAQ: PUBM) operating a supply-side platform (SSP) that powers programmatic advertising for publishers, media buyers, commerce media, and AI agents across CTV, mobile app, online video, display, and audio. Its unified platform combines an SSP for monetization and demand access, the OpenWrap header-bidding wrapper (an open-source Prebid-based wrapper with web, iOS, Android, Flutter, and Unity SDKs), Connect for curation and audience activation, Activate for buyer-side supply-path optimization and direct-to-publisher deals, Convert for commerce/retail media, Identity Hub for identity orchestration, and AgenticOS for agent-driven campaign planning and execution. PubMatic processes trillions of bids per day across global infrastructure, and exposes its programmatic surface primarily via the OpenRTB protocol, prebid integrations, and embedded SDKs rather than a public REST developer portal — making this profile a directory of PubMatic's products, OpenWrap repos, sample apps, and supply-chain endpoints rather than a tier-1 OpenAPI-backed catalog.
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 PubMatic the way a machine reads it — 3 machine-readable artifacts, 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 — PubMatic scores 12.6/100 (minimal), with a separate agent-readiness read of 12/100 (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.
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.

How we profile PubMatic
Each block below is one kind of artifact we hold for PubMatic. 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.
MCP Servers 1
Model Context Protocol servers expose these APIs directly to AI agents. We profile them because agent-native access is the fastest-growing way this provider's capabilities actually get used.

MCP SERVERGraphQL 1
Where a provider ships GraphQL, the schema is the contract. We profile it alongside the REST surface so the whole interface is legible in one place.
GraphQL schemas published by this provider.

GRAPHQLSecurity Posture 1
Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.
