How this service works
Chat, embeddings, OCR, speech-to-text, image editing, image understanding (captioning/Q&A), text-to-speech, translation, writing tools, classification tools, developer tools, local utilities, format/checksum validators, encoding & crypto utilities, date/time calculators, geo/coordinate math, math & finance calculators, novelty tools, and business/social writing generators — 179 endpoints in all, across multiple specialized self-hosted models. Pay per call with crypto — no signup — or get an API key.
Output
Returns a lint result indicating whether the commit message is valid, along with any detected style violations, missing components, or convention errors (e.g. missing type prefix, subject too long, incorrect formatting per Conventional Commits spec).
Example use cases
Pre-push commit message check
“Before I push, can you check this commit message and tell me if it follows conventional commit style: 'fix: resolved null pointer exception in user service'?”
CI pipeline commit validation
“Lint this commit message for me and flag any issues: 'WIP added some stuff to the login page and fixed a bug'”
Team commit convention enforcement
“Does this commit message meet conventional commit standards? 'refactor(api)!: restructure endpoint routing for v2 compatibility'”
