ViralGains

ViralGains is an advertising technology platform that collects consumer feedback directly within digital ad units as zero-party data, then combines that real-time, consented consumer input with its VoiceAlike AI to build higher-quality audiences and deliver more relevant, privacy-respecting advertising for brands and agencies. The platform spans zero-party data collection, brand lift measurement, and a dedicated health and pharma offering (VG Health). ViralGains was surfaced as a portfolio company of 500 Global and added to the API Evangelist network. As of this enrichment pass the company publishes a marketing and product website but no public developer program, API documentation, or machine-readable API surface.

ViralGains is profiled on the APIs.io network. Tagged areas include Company, Advertising, AdTech, Zero-Party Data, and Marketing.

ViralGains’ developer surface includes engineering blog, support, and 11 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Health 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.
The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% 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/.

  detail: ViralGains runs a WordPress marketing site and nothing else — api., developer., developers. and docs.viralgains.com
    are all NXDOMAIN, the 41-URL Yoast page sitemap contains no developer, API, docs or pricing page, and the FAQ routes all
    implementation questions to 800-501-2763 and hello@viralgains.com because media is activated through third-party DSPs
    and SSPs rather than a ViralGains API.
