Akashi Code Reality CheckService

Akashi Code Reality Check: tells an AI coding agent whether the packages, versions and symbols it is about to use actually exist, across npm, PyPI, crates.io, Go, Maven, RubyGems, Packagist and NuGet. POST /v1/check with {"language","code"} (Python, TypeScript, JavaScript, Go, Rust) returns a diagnostic per import and call: nonexistent package, likely typo-squat, placeholder, suspiciously new, deprecated or nonexistent symbol. POST /v1/package(s), /v1/versions and /v1/symbol(s) answer single questions (exists, latest, yanked, deprecated, the real alternatives). Every response is a JSON object, errors included ({"error":{"code","message","retryable"}} with 4xx). Upstream outages give partial results listed in unavailable, never a 5xx.
