# Metalenz > Metalenz is a fabless semiconductor optics company in Boston, Massachusetts that commercialises > meta-optics — flat metasurface lenses that replace stacks of curved refractive elements with a > single planar chip, patterned by nanostructures and mass produced in a standard semiconductor > foundry. Founded in 2016 by Rob Devlin and Federico Capasso out of the Capasso Lab at Harvard, > holding the exclusive worldwide licence to that lab's metasurface IP. **This file is not published by Metalenz.** metalenz.com/llms.txt returns 404. This is an API Evangelist-generated index of the company's public, machine-readable surface, built from artifacts in https://github.com/api-evangelist/metalenz on 2026-08-25. ## What Metalenz sells Optical components, IP licences and full-stack biometric solutions — to device makers and semiconductor foundries, not to developers. - **PolarEyes** — the polarization imaging platform the products sit on - **Polar ID** — single-camera polarization face authentication for smartphones, working under a fully powered-on OLED display; uses the Samsung ISOCELL Vizion 931 sensor and the Qualcomm Snapdragon imaging stack - **Polar 3D** — on-device relightable selfies and avatars from a single image - **Orion** / **Gemini** — dot-pattern projectors for structured-light 3D sensing Manufacturing and licensing partners named publicly: STMicroelectronics, UMC. Investors named publicly: Neotribe Ventures, Intel Capital, TDK Ventures, 3M, Applied Ventures, M Ventures, Braemar Energy Ventures, Foothill Ventures. ## There is no developer program - No developer portal. `developer.metalenz.com` does not resolve. - No API host. `api.metalenz.com` does not resolve. - No status page. `status.metalenz.com` does not resolve. - No SDK for any product, in any language, in any registry. - No OpenAPI, AsyncAPI, GraphQL schema, `.proto` or WSDL published anywhere. - No `/.well-known/` documents at all — eight paths probed, all 404, control probe confirms the host is not a catch-all. - No MCP server, no A2A agent card, no webhooks, no events. - Product documentation exists at **https://docs.metalenz.com/** but it is gated: the `/documentation/` path redirects into Microsoft Entra ID and is reachable only by customers, licensees and foundry partners. ## What IS machine-readable The marketing site runs WordPress 6.8.2 with its REST API open, so the company's own content is available as JSON, anonymously and read-only. Base URL: `https://metalenz.com/wp-json` - [Press Releases API](https://metalenz.com/wp-json/wp/v2/posts): 26 published items back to the February 2021 launch out of stealth. The WordPress `post` type is labelled "Press Releases" here. - [Pages API](https://metalenz.com/wp-json/wp/v2/pages): 29 pages — product, technology, market, company and legal. Pages nest; PolarEyes is the parent of Polar ID and Polar 3D. - [Media API](https://metalenz.com/wp-json/wp/v2/media): 418 attachments — product imagery, metasurface diagrams, event photography, brand and sub-brand logos. - [Taxonomy API](https://metalenz.com/wp-json/wp/v2/tags): 1 category, 2 tags. Thin and unmaintained. - [Search API](https://metalenz.com/wp-json/wp/v2/search): cross-content search. Substring `LIKE` match, not ranked full text — searching "SEMI" returns 26 hits because they contain "semiconductor". - [Discovery API](https://metalenz.com/wp-json/): the route index — 212 routes across 13 namespaces — plus content types, taxonomies and statuses. - [oEmbed API](https://metalenz.com/wp-json/oembed/1.0/embed): oEmbed 1.0 rich cards for any metalenz.com URL, JSON or XML. ## How to consume it - Anonymous. No key, no token, no account. `Allow: GET`. - `per_page` is 1..100; out of bounds returns `400 rest_invalid_param` with the exact bound. - Page by the RFC 8288 `Link: rel="next"` header. `X-WP-Total` / `X-WP-TotalPages` give counts. - Send `_fields=` to trim responses; a full page record is ~22KB. - Add `_embed` to inline author, featured media and terms in one round trip. - Errors are the WordPress envelope `{code, message, data:{status}}` as `application/json` — **not** RFC 9457 problem+json. - **401 means stop, not authenticate.** There is no public credential path; the only method the server declares is WordPress application passwords, issued from the site admin. - `POST /batch/v1` is blocked at the Fastly/Pantheon edge with a plain-text `403 Request has been blocked.` — handle a non-JSON 4xx body. - No rate-limit headers of any family, no `Retry-After`, no 429 observed. Self-throttle. - Responses are `cache-control: public, max-age=604800` behind Fastly. Treat as an archive, not a feed. - **`/wp/v2/users` returns real people.** It answers anonymously. It is documented structurally in this profile and deliberately excluded from every skill and tool here. Do not enumerate it. ## Open source github.com/Metalenz holds three public repositories — none of them an API client. Two are first-party Julia packages from the metasurface inverse-design team (`FlexibleFunctors.jl`, registered in the Julia General registry at 0.1.6, last tagged 2021-07-19; `InfiltrateRRule.jl`, unregistered) and one is a fork. Ownership is confirmed by corporate-domain authorship in their `Project.toml` files. ## Profile artifacts - OpenAPI (7 documents, 23 operations): `openapi/` - Authentication: `authentication/metalenz-authentication.yml` - Errors: `errors/metalenz-problem-types.yml` - Conventions and reversibility: `conventions/metalenz-conventions.yml` - Data model: `data-model/metalenz-data-model.yml` - Conformance: `conformance/metalenz-conformance.yml` - Lifecycle: `lifecycle/metalenz-lifecycle.yml` - Rate limits: `rate-limits/metalenz-rate-limits.yml` - Plans and pricing: `plans/metalenz-plans-pricing.yml` - Packages: `packages/metalenz-packages.yml` - Well-known probe: `well-known/metalenz-well-known.yml` - Candidate MCP tools and crosswalk: `mcp/` - Agent skills: `skills/` - Examples: `examples/metalenz-examples.yml` ## Company links - Website: https://metalenz.com/ - About: https://metalenz.com/about-us/ - Products: https://metalenz.com/all-products/ - Technology: https://metalenz.com/our-technology/ - What are meta-optics: https://metalenz.com/what-are-meta-optics/ - Press releases: https://metalenz.com/press-releases/ - Media coverage: https://metalenz.com/media-coverage/ - Events: https://metalenz.com/events/ - Careers: https://metalenz.com/careers/ - Contact: https://metalenz.com/contact-us/ — sales@metalenz.com - Terms and Conditions of Sale: https://metalenz.com/terms-and-conditions-of-sale/ - RSS: https://metalenz.com/feed/ - GitHub: https://github.com/Metalenz - LinkedIn: https://www.linkedin.com/company/metalenz/ There is no pricing page, no plans page and no signup anywhere on metalenz.com.
