Lens Protocol

Lens Protocol is an onchain social graph and a developer platform for building social applications where users own their profile, content, and relationships. Originally launched on Polygon PoS, Lens has since evolved into Lens Chain — an L2 zkEVM rollup purpose-built for social — with the Lens v3 contracts redesigned around primitives like Accounts, Apps, Feeds, Groups, Graphs, and Actions. Developers integrate Lens through the Lens API (a GraphQL gateway over the indexed chain state), the Lens TypeScript SDK and React SDK, the underlying smart contracts, and an authentication layer that issues short-lived auth tokens after a SIWE-style signature. Lens powers social clients (Hey, Orb, Tape, Buttrfly), creator tools, and composable mini-apps that share the same onchain social graph.

Lens Protocol is listed with 6 APIs on the APIs.io network. Tagged areas include Lens Protocol, Onchain Social, Web3, Social Graph, and Polygon.

Lens Protocol’s developer surface includes documentation, engineering blog, and 14 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 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.

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