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. 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.

PubMatic publishes 1 API on the APIs.io network. Tagged areas include Advertising, AdTech, Programmatic Advertising, Supply Side Platform, and SSP.

PubMatic’s developer surface includes engineering blog, YouTube channel, documentation, authentication, changelog, and 46 more developer resources.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/pubmatic: open an issue to ask a question, or submit a pull request to add artifacts.
