Knotch is a New York-based content intelligence company founded by Anda Gansca and Aron Tzimas. Its Knotch One platform measures and optimizes owned-content performance for enterprise marketing teams, and its newer product, Ace, is positioned as AI experience infrastructure for the conversational web: it ingests a brand's existing web properties, content hubs, video and feeds, atomizes them into modular content units tagged by topic, audience, funnel stage and intent, then composes adaptive page experiences for human visitors while emitting structured, citable content for AI agents and answer engines. Named enterprise customers include Google, Deloitte, Ally, Zillow, Cox Automotive, GEICO, Synchrony, Square, Dropbox, FOX and Chime. Knotch does publish a developer surface, on two hosts that are not linked from the marketing site: docs.knotch.it documents the browser-side Measurement Unit API, Event Pixel and Verification Pixel, and help.knotch.com documents the server-side Knotch Events API v1.1, which accepts batched conversion events over HTTPS with Bearer authentication and is backed by a live OpenAPI 3.1.0 definition served at https://events.knotch.it/openapi.json. Credentials are issued by Client Success rather than self-service, and no pricing, status page, changelog, SDK or public GitHub organization is published.
Knotch publishes 2 APIs on the APIs.io network: Events API and Health API. Tagged areas include Company, Content Intelligence, Content Marketing, Analytics, and Artificial Intelligence.
Knotch’s developer surface includes documentation, API reference, getting-started guide, support, authentication, sandbox, and 20 more developer resources.
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.
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/knotch: open an issue to ask a question, or submit a pull request to add artifacts.

note: 'Documentation, the OpenAPI and the client-side tag APIs are public and anonymous, but credentials are not self-service:
the Events API states "To obtain or rotate an API key, contact your Knotch Client Success Manager", the Event Pixel requires
a Measurement Account ID from Client Success, and the Verification Pixel requires a kvpid issued via blueprint@knotch.com.
No pricing page and no self-service signup are published.'

description: Server-side conversion event ingestion. Accepts batches of up to 100 events over HTTPS with Bearer authentication,
so conversions that happen off-site (CRM milestones such as ClosedWon, BecameSQL or Renewal, data-warehouse or marketing-automation
outcomes) can be measured and attributed alongside on-site conversions in Knotch One, where they surface as "API Conversions".
A simulate=true query parameter validates a payload without storing data. A Segment Webhook destination endpoint is also
supported and is the only path present in the published OpenAPI.

note: Contract discovery corrected a wrong prior finding. The 2026-07-19 pass recorded "no-public-api-surface"; a live OpenAPI
3.1.0 was found on the API host root at https://events.knotch.it/openapi.json, and two public documentation hosts (docs.knotch.it,
help.knotch.com) were harvested. Neither documentation host is linked from knotch.com, which is why the first pass missed
them.
