## APIs

None published. There is no developer portal, API reference, OpenAPI/AsyncAPI specification, SDK, CLI, MCP server, webhook catalog, sandbox, or status page on any Antimatter Systems host as of 2026-07-19. No `/.well-known/` discovery documents are served, and `docs.` and `developer.` subdomains do not resolve. There are no first-party client libraries on npm or PyPI.

## Disambiguation

Antimatter Systems (antimatter.systems, playantimatter.com) is **not** Antimatter (antimatter.io, docs.antimatter.io), an unrelated GenAI data access-control vendor that does publish a REST API, OpenAPI specification, CLI and Python SDK. Search results for "Antimatter API" almost always refer to that other company, or to the unrelated *Antimatter Dimensions* game and *Antimatter API* Minecraft mod.
