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.
Limited machine-readable signal and partial portal coverage — documentation a human can read, but little a machine or agent can consume without scraping.
API Evangelist profiles Impossible Metals the way a machine reads it — 14 machine-readable artifacts across 10 APIs, pulled from the provider's own public surface and indexed so a developer, an analyst, or an AI agent can evaluate it against every other provider on the network.
Every provider in the network is reduced to the same set of machine-readable artifacts — OpenAPI contracts, event specifications, GraphQL schemas, runnable collections, pricing and rate-limit signals, security posture, OAuth scopes, and the agent surfaces (MCP servers and skills) that let software drive the API on its own. We profile them because the interface is the part of a company you can actually inspect: it is a truer signal of what a provider does than any marketing page. From those artifacts we compute the Kin Score — Impossible Metals scores 31.9/100 (thin), with a separate agent-readiness read of 44/100 (agent ready). The full breakdown is below, followed by every artifact we hold — each card links through to its machine-readable definition on apis.io.
Kin Score
This is the API Evangelist rating — a single, repeatable read computed from the artifacts on this page. Green fill is points earned; the red track is points possible, so every bar shows earned-versus-possible at a glance.

How we profile Impossible Metals
Each block below is one kind of artifact we hold for Impossible Metals. For each we say what it is and why it earns a place in the profile, then list every one we've indexed — capped at two rows, scroll within the panel for the rest.
APIs 10
Each API is captured as its own OpenAPI definition — every operation, parameter, and response. This is the single most useful machine-readable description of what an API does, and it's what lets us score, lint, mock, and generate against it without asking the provider for anything.

Pricing Plans 1
Pricing is part of the interface. Machine-readable plans tell you what a tier costs and includes before you commit — one of the things the Kin Score reads for access clarity — renamed from commercial clarity in rubric 0.12, because a free statutory interface has access terms and no commercial ones.
Published pricing tiers and plan structures.
Rate Limits 1
Rate limits are the difference between a demo that works and a production integration that doesn't fall over. Publishing them is an operational-transparency signal — and a hard requirement for any agent that plans its own throughput.
Documented rate limits and quota policies.

Authentication, domain security, vulnerability disclosure, and trust-center signals — the evidence that a provider takes security seriously enough to document it. We profile it because you can't govern what you can't see.

This is an independent, third-party profile of Impossible Metals, published by API Evangelist. We do not operate, host, resell, or support these APIs, and we are not affiliated with or endorsed by the company unless stated above. Everything here is built from publicly available information — the company's own site, developer portal, documentation, public repositories, and the specifications it publishes for public use. Nothing is obtained by breaching a system, defeating an access control, or using credentials.
The Kin Score and Agent Readiness rating are independently calculated assessments of a company's public API artifacts, scored against a published rubric. They are not certifications, endorsements, security assessments, or audits.
Corrections, re-scores, and removal are free — no partnership or purchase required, and you do not need to justify the request. A removed company is recorded as unrated, never scored zero for having asked. Acknowledgement within one business day; removal within two.
