When an external API changes, your tested PR is already waiting in GitHub.
Stop waking up to broken production webhooks and deprecated parameters. Self-Maintaining APIs diffs OpenAPI specs, scans your repository ASTs, tests the migration in disposable sandboxes, and opens clean pull requests.

The Zero-Regression Pipeline
How our code agents transform breaking OpenAPI diffs into merged pull requests.
1. OpenAPI Diff Ingestion
Continuous ingestion of OpenAPI 3.0/3.1 specifications, SDK releases, and developer changelogs across payment, AI, and cloud communication providers.
2. Disposable Container Sandboxes
Customer repositories are cloned into isolated, temporary sandbox containers. We run your existing test suite before and after the AST patch to guarantee zero regressions.
3. Verified PR Generation
A tested branch with clean conventional commit messages and rich explanation diffs is opened against your main branch ready for 1-click review.
