Syncly

Syncly is an AI-native social and customer intelligence platform (backed by Y Combinator, SoftBank, 500 Global, and Rebel) that unifies customer feedback and social conversations into a single source of truth. It aggregates feedback from tickets, chat, email, surveys, reviews, and social, then uses AI to auto-tag, cluster, and sentiment-score every message into the themes that matter. Its social intelligence surface listens across TikTok, Reels, and Shorts with speech-to-text and vision AI for competitive analysis, creator discovery, and campaign measurement, while "Hey Syncly" lets teams query their data in plain language. Syncly exposes its data to AI assistants through a hosted remote MCP connector (Claude, ChatGPT, Cursor, and more) rather than a public REST API.

Syncly publishes 2 APIs on the APIs.io network: Health API and .well Known API. Tagged areas include Company, Social Intelligence, Social Listening, Customer Feedback, and Voice of Customer.

Syncly’s developer surface includes documentation, getting-started guide, engineering blog, pricing, signup flow, authentication, and 23 more developer resources.

Create-or-Update Ergonomics does not apply to this provider. The published contracts declare no write operations, and a read-only API cannot create-or-update. The facet is excluded from this provider's denominator entirely — not scored zero. A reference or data API is not deficient for being unable to upsert.

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