01 Capabilities

Built for pipelines, not just developers.

Bumpkit is designed to be called in CI, not just by humans reading docs.

1.1

Built for messy history

Conventional-commit parsers choke on real repos. Bumpkit reads wip, fix stuff, and three-word commit messages the way a teammate would. Low-signal noise is filtered and flagged, never silently dropped.

1.2

Confidence scoring

Every response includes a 0 to 1 confidence score. Agents can decide whether to auto-publish or hand off to a human review step.

1.3

Structured JSON output

Sections, entries, bump type, reasoning: all structured. Plus a pre-formatted string for humans. Machines and people both get what they need.

1.4

Partial responses

Low-confidence results return status: partial, not an error. Agents get usable data with clear warnings instead of crashing or silently succeeding.

1.5

Rate limit headers

Every response includes X-RateLimit headers so agents can track remaining quota and schedule retries without hitting walls.

1.6

Commit deep links

Pass a repository URL and Bumpkit auto-generates GitHub, GitLab, or Bitbucket commit links directly in the changelog output.

02 Interface

One endpoint. Everything you need.

POST /v1/analyze returns the version bump, full changelog, and confidence in a single call.
