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. Its one reachable agent-facing API is the PubMatic MCP Server at https://mcp.pubmatic.com/mcp, whose specifications, integration guides and packaged Agent Skills PubMatic publishes openly at github.com/PubMatic/pubmatic-mcp-server even though the endpoint itself is account-gated; the customer API reference at help.pubmatic.com sits behind an Okta/Auth0 login, and no OpenAPI, AsyncAPI, GraphQL or A2A agent card is served on any PubMatic host.
