Channel99

Channel99 is a B2B marketing performance and attribution platform founded by Demandbase creator Chris Golec. It uses AI and first-party account identification to unify cross-channel marketing results, verify B2B ad delivery, reveal the "dark funnel" and view-through traffic, and benchmark vendor and channel performance against the industry, then recommend budget and campaign changes that grow pipeline while reducing wasted spend. Marketing and RevOps teams export unified performance data into data warehouses (Snowflake), CDPs, and BI tools, and activate intent-based audiences. Developers reach the same data through the Pulsar Reporting API, a documented OAuth-issued M2M REST surface of visit, pageview, impression and intent facts with cursor pagination, and through a first-party read-only MCP server that connects Channel99 marketing intelligence to ChatGPT and Claude. Backed by Norwest Venture Partners, Jackson Square Ventures, Industry Ventures, Ridge Ventures, Geek Ventures, and Marin-Sonoma Impact Ventures.

Channel99 publishes 18 API contracts indexed on the APIs.io network, including Ad Accounts API, Ad Campaign Groups API, Ad Campaigns API, and 15 more. Tagged areas include Company, Marketing, Analytics, Attribution, and B2B.

The Channel99 catalog on APIs.io includes 1 Spectral governance ruleset.

Channel99’s developer surface includes authentication, documentation, API reference, support, getting-started guide, engineering blog, signup flow, and 24 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.

The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Agent readiness — checks not met, largest first (exact, from this profile):

Agentic Access Contract +10 pts — agentic_access artifact present (x-agentic-access), graded by author
Idempotency +9 pts — OpenAPI mutating operations declare an idempotency key — a header, a request-body property, or a named de-duplication token whose own description says so (verified); else common[].type matches /idempoten/i (documented)
A2A Agent Card +8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0
Registration Without a Human +6 pts — a `registration_endpoint` in the served RFC 8414 / OIDC discovery document
Delegated User Identity +6 pts — a served discovery document listing authorization_code in grant_types_supported (served), else an oauth2 authorizationCode flow or openIdConnect declared in an OpenAPI (documented)
Typed Event Surface +6 pts — AsyncAPI document, OR webhooks/callbacks objects in the as-published OpenAPI, OR common[].type includes Webhooks

7 more unmet checks in the Agent Readiness table above.

Kin Score — facets with the most composite points still available (weight × headroom):

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 the provider profile at artifacts.apis.io/channel99/apis.yml: open an issue on github.com/api-evangelist/channel99 to ask a question or point us at an artifact you publish.
