Lytics is a customer data platform (CDP) that provides two concurrent REST APIs for managing unified user profiles, behavioral audiences, content affinity scoring, campaign flows, and real-time personalization. The v2 API (886 paths / 1,331 operations) covers accounts, authorizations, connections, schema and identity configuration, data models, streams, jobs and ML models; the v1 API still owns data collection, personalization, entity lookup and content classification. Lytics ingests data from 100+ sources, builds predictive audiences, and activates them across advertising networks, email providers, data warehouses and on-site personalization. Lytics joined Contentstack in January 2025.
Lytics publishes 34 APIs on the APIs.io network, including Account API, Account Settings API, Auth API, and 31 more. Tagged areas include Customer Data Platform, CDP, Personalization, Segmentation, and User Profiles.
The Lytics catalog on APIs.io includes 1 event-driven AsyncAPI specification, 1 JSON-LD context, and 1 Spectral governance ruleset.
Lytics’ developer surface includes authentication, documentation, engineering blog, pricing, changelog, support, CLI, and 49 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/.
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/lytics: open an issue to ask a question, or submit a pull request to add artifacts.

for sub-divisions, etc..
The Account resource has the following attributes:
