#lens

Live data from Lens Protocol, the decentralized social graph where accounts, posts and follows are owned on-chain by users rather than by a platform — read from the public Lens v3 GraphQL API, no key, nothing stored. The account endpoint resolves a Lens username (or wallet address) to its on-chain profile: display name, bio, picture and address. The stats endpoint returns that account's social graph — follower and following counts plus its post, comment, repost, quote and collect totals. The posts endpoint returns an account's recent publications, each with its text, timestamp and full engagement (reactions, comments, reposts, quotes, bookmarks, collects). The feed endpoint returns the latest posts across the entire network. Look up any Lens handle, read their reach and pull their content as structured JSON. This is the decentralized-social cut — Web3-native social data distinct from the centralized-platform social APIs and from the crypto price and market APIs in the catalogue.

Thin-lens and mirror imaging optics as an API, computed locally and deterministically. The lens endpoint applies the thin-lens equation, 1/f = 1/do + 1/di, and solves for whichever of the focal length, object distance or image distance you leave out, then returns the magnification m = −di/do and the full description of the image — real or virtual, upright or inverted, enlarged, reduced or the same size — and whether the lens is converging (convex, f > 0) or diverging (concave, f < 0). The mirror endpoint does the same for a spherical mirror, taking the focal length or the radius of curvature (f = R/2), classifying it as concave or convex and describing the image. The power endpoint converts between focal length in metres and optical power in diopters, D = 1/f, and combines several thin lenses placed in contact by adding their powers, D_total = ΣD, returning the combined focal length. Distances use whatever consistent unit you supply. Everything is computed locally and deterministically, so it is instant and private. Ideal for physics and optics-education tools, lens and optical-system design, eyewear and vision apps, and photography learning. Pure local computation — no key, no third-party service, instant. Live, nothing stored. 3 endpoints. This is geometric-optics imaging; for Snell's-law refraction angles use a Snell API and for camera depth of field and field of view use a photography API.
