# Impossible Metals > Impossible Metals is a deep-ocean robotics and critical-minerals company (founded 2020, San Jose CA, > robotics lab in Canada, Y Combinator W22, certified B Corp). It builds the Eureka autonomous underwater > vehicle, which hovers above the seabed and uses computer vision and robotic arms to pick polymetallic > nodules one at a time, leaving visible fauna and the sediment layer in place. Eureka III is slated for a > 2026 test in the BGR contract area of the Clarion-Clipperton Zone. GENERATED, NOT PUBLISHED. Impossible Metals does not serve an llms.txt — https://impossiblemetals.com/llms.txt returned HTTP 404 on 2026-08-23. This file was generated by API Evangelist from the company's own public surface and from the artifacts in this repository. It is an independent third-party profile. ## What is and is not here Impossible Metals is a mining and robotics company, not a software vendor. It has NO developer program, NO product API, NO SDKs, NO CLI, NO developer portal, NO API pricing, NO status page and NO api./developer./docs. subdomain — each of those was probed on 2026-08-23 and each is genuinely absent. What it DOES serve, by default and without advertising it, is the WordPress REST content API behind impossiblemetals.com, plus two OpenAPI documents its events plugin publishes on that same host. All of it is anonymously readable, read-only, and free. That is the surface described below. ## Base URL https://impossiblemetals.com/wp-json No key, no token, no signup. Send an identifying User-Agent: Cloudflare answers 403 to some requests without one. ## Content surfaces (counts verified live 2026-08-23) - [FAQ knowledge base](https://impossiblemetals.com/wp-json/wp/v2/avada_faq): 141 entries across 11 categories. The company's own structured position on nodule collection, environmental impact, regulation, competitors, techno-economics and myth-busting. This is the highest-value resource on the surface. - [FAQ categories](https://impossiblemetals.com/wp-json/wp/v2/faq_category): 11 terms. - [Posts](https://impossiblemetals.com/wp-json/wp/v2/posts): 247 blog posts, press releases and congressional testimony. - [Pages](https://impossiblemetals.com/wp-json/wp/v2/pages): 93 technology, sustainability, markets and policy pages. - [Media](https://impossiblemetals.com/wp-json/wp/v2/media): 727 attachments — Eureka photography, seabed imagery, diagrams, report PDFs. - [Categories](https://impossiblemetals.com/wp-json/wp/v2/categories): 16 terms. [Tags](https://impossiblemetals.com/wp-json/wp/v2/tags): 2 terms. - [Authors](https://impossiblemetals.com/wp-json/wp/v2/users): 8. - [Search](https://impossiblemetals.com/wp-json/wp/v2/search): 586 searchable objects across every type. - [Route index](https://impossiblemetals.com/wp-json/): 269 routes across 23 namespaces, with full argument schemas. - [oEmbed](https://impossiblemetals.com/wp-json/oembed/1.0/embed): oEmbed 1.0 provider, JSON or XML. ## Events - [Events, venues, organizers](https://impossiblemetals.com/wp-json/tribe/events/v1/events): live and anonymous. 40 venues and 22 organizers at capture; the forward-looking events window returned 0 upcoming events. - [Published OpenAPI 3.0.0](https://impossiblemetals.com/wp-json/tribe/events/v1/doc) for that surface. - [Published OpenAPI 3.0.4](https://impossiblemetals.com/wp-json/tec/v1/docs) for the successor /tec/v1/ surface. CAUTION: the contract is published but every /tec/v1/ route answers HTTP 400 missing_experimental_endpoint_acknowledgement to an anonymous call, and the required header name is documented nowhere on the site. Use /tribe/events/v1/ instead. ## How to call it - Pagination: ?page= and ?per_page= (max 100). Read X-WP-Total and X-WP-TotalPages, plus an RFC 8288 Link header. The /tribe/events/v1/ surface is different — it paginates in the JSON body (total, total_pages, next_rest_url). - Trim payloads with ?_fields=id,title,link and resolve linked records with ?_embed. - Filter with ?search=, ?categories=, ?tags=, ?slug=, ?after=/?before=, ?orderby=/?order=. - Errors are the WordPress envelope {"code","message","data":{"status"}} served as application/json. It is NOT RFC 9457 problem+json. Key on `code`, never on `message`. - No rate limits are published and NO rate-limit headers are returned — not X-RateLimit-*, not RateLimit-*, not Retry-After. You cannot see your headroom. Honour cache-control and back off on any 403 or 5xx. ## Where the company's real data lives (not in an API) Impossible Metals publishes environmental and test data from the Eureka programme as files on Google Drive, linked from https://impossiblemetals.com/sustainability/public-data/ — the Eureka II April 2024 deep-ocean test data and the Eureka III DHI collector-plume modelling report. There is no data catalog endpoint, no DCAT or CKAN surface, and no machine-readable access to any of it. ## Human pages - [Home](https://impossiblemetals.com/) · [About](https://impossiblemetals.com/about/) · [Technology](https://impossiblemetals.com/technology/robotic-collection-system/) - [FAQ](https://impossiblemetals.com/frequently-asked-questions/) · [Sustainability](https://impossiblemetals.com/sustainability/) · [Public data](https://impossiblemetals.com/sustainability/public-data/) - [Blog](https://impossiblemetals.com/news/blog/) · [Press releases](https://impossiblemetals.com/news/press-releases/) · [RSS](https://impossiblemetals.com/feed/) - [Partners](https://impossiblemetals.com/about/partners/) · [Board & advisors](https://impossiblemetals.com/about/board-advisors/) · [Careers](https://impossiblemetals.com/join-us/) - [Contact](https://impossiblemetals.com/contact/) · [Privacy](https://impossiblemetals.com/policies-reports/privacy-statement/) ## Agent surfaces None. No MCP server (probed /mcp, /.well-known/mcp.json, mcp.impossiblemetals.com — all absent), no A2A agent card (/.well-known/agent-card.json and /.well-known/agent.json both 404 on both hosts), no /.well-known/ documents of any kind, and no published llms.txt. A candidate MCP tool list derived from the REST surface is in mcp/impossible-metals-mcp.yml in this repository, clearly marked as a candidate that Impossible Metals does not publish. ## Corrections This is an independent profile.
