Autonomous Refactoring

From breaking changes
to merged PRs —
zero hallucinations.

Tools like Dependabot only bump version numbers in configuration files. ApiPatch understands actual code semantics, validates changes through AST syntax trees, and submits ready-to-merge Pull Requests.

DocHunter™ Grounding: Resolves live PyPI/npm documentation and changelogs before writing code.
AST Self-Healing: Detects and repairs LLM syntax or structural errors automatically.
Atomic GitHub Commits: Opens live PRs directly on target repositories via Git Database REST API.

AST Safety Guard: Parsed AST syntax tree, 100% logic and docstrings intact

Under The Hood

Engineered for real-world production codebases.

Zero guesswork. Grounded in live documentation, secured by AST compilers, and delivered via atomic Git commits.

DocHunter™ Live Grounding

Instantly pulls live official documentation, changelogs, and migration guides from PyPI, npm, and GitHub APIs in under 100ms to eliminate hallucinations.

AST Self-Healing Loop

Parses refactored Python and JavaScript/TypeScript through AST linters. If syntax or structural errors occur, ApiPatch automatically prompts the AI to self-heal.

Autonomous GitHub PR Pipeline

Run apipatch pr owner/repo to audit remote repositories, fork, create isolated branches, commit refactorings, and open live PRs automatically.

10x Parallel Async Auditing

Multi-threaded candidate file pre-filtering scans thousands of files concurrently using lightweight fast AST regex parsers before invoking the LLM.

Multi-LLM Engine

Optimized for Google Gemini 2.5 Flash Lite, Anthropic Claude 3.7 Sonnet, and OpenAI GPT-4o with automatic fallback and key discovery.

GitHub App & Webhook Daemon

Run apipatch webhook on your CI/CD server or cloud container to receive push webhooks and maintain 100% up-to-date dependencies 24/7.
