Impossible Metals

Impossible Metals is a deep-ocean robotics and critical-minerals company founded in 2020 by CEO Oliver Gunasekara, headquartered in San Jose, California with a robotics lab in Canada, and a member of Y Combinator's W22 cohort. It builds the Eureka autonomous underwater vehicle, a hovering AUV that uses computer vision and robotic arms to pick polymetallic nodules from the seabed one at a time — leaving visible fauna and the sediment layer in place — as an alternative to the dredge-and-riser designs used elsewhere in deep-sea mining. Eureka I and Eureka II have been sea-tested, Eureka III is slated for a 2026 test in the BGR contract area of the Clarion-Clipperton Zone, and the company has applied for a deep-sea mining lease in U.S. federal waters and for observer status with the International Seabed Authority. It is a certified B Corp and publishes environmental data, policy positions and testimony alongside its technical work. Impossible Metals is a robotics and mining company rather than a software vendor: it operates no developer program, publishes no product API, SDKs or developer portal, and hosts no api. or developer. subdomain. The only machine-readable interfaces it serves are the WordPress REST content API behind impossiblemetals.com and the two OpenAPI documents its events plugin publishes on that same host, which are captured here for discovery purposes and are anonymously readable and read-only.

Impossible Metals publishes 10 APIs on the APIs.io network, including Posts API, Pages API, FAQ API, and 7 more. Tagged areas include Company, Deep Sea Mining, Critical Minerals, Battery Metals, and Robotics.

Impossible Metals’ developer surface includes engineering blog, support, FAQ, YouTube channel, authentication, code examples, and 24 more developer resources.
