Apsalar

Apsalar was a mobile marketing analytics and attribution company (founded 2010, headquartered in San Francisco, backed by Battery Ventures and 500 Startups/500 Global) that provided a mobile measurement platform (MMP) for app install attribution, campaign analytics, and marketing data unification. In 2017 Apsalar merged into Singular (singular.net); the Apsalar brand and its developer/API surface were retired as part of that acquisition. The apsalar.com apex domain no longer resolves to a live site and www.apsalar.com now redirects to Singular, so there is no active first-party API, OpenAPI, or developer portal to enrich. This profile is retained as an acquired-company lead pointing to its successor, Singular.

Apsalar is profiled on the APIs.io network. Tagged areas include Company, Analytics, Mobile, Attribution, and Marketing.

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/apsalar: open an issue to ask a question, or submit a pull request to add artifacts.
