The Problem

Silent API changes
are breaking production

Every time a major SDK ships — OpenAI v1.0, Pydantic v2, Stripe SCA, LangChain LCEL — engineering teams spend days hunting broken calls and rewriting legacy code by hand.

⏳
Days of downtime
wasted per breaking SDK release
🔥
30% of cloud outages
caused by silent API breaking changes
🤦
Dependabot fails you
only bumps version numbers — never fixes code
# Dependabot "fixes" your requirements.txt
- openai==0.28.0
+ openai==1.50.0

# But your code is still broken at runtime
response = openai.ChatCompletion.create(
model="gpt-4", messages=[...]
)

# AttributeError: module 'openai' has no
# attribute 'ChatCompletion'
→ Production is DOWN 🔥
The Solution

ApiPatch autonomously fixes
what humans hate doing

1
🔍 Detects Breaking Changes
Scans any Python/JS/TS codebase for deprecated API calls across any third-party library — no hardcoded rules needed.
2
🌐 DocHunter™ Live Grounding
Fetches official PyPI/npm/GitHub docs & changelogs in <0.1s to eliminate LLM hallucinations.
3
🤖 LLM Refactoring Engine
Gemini 2.5 Flash Lite rewrites broken code with AST self-healing feedback loop — syntax-safe, logic-preserving.
4
✅ Opens Ready-to-Merge PRs
Auto-forks, commits atomically via GitHub API, and opens real Pull Requests engineers can review in seconds.
# ApiPatch fixes everything automatically

The Founder

Built by a solo technical founder

🧑‍💻

Morad Moqbel

Founder & CEO · ApiPatch · Ibb, Yemen
Solo Technical Founder Python · Node.js · AI/LLMs Applying: YC Fall 2026
✓Built full MVP — PyPI + CLI + Docker + CI/CD — in days, not months
✓Deep expertise in AI agents, GitHub API, AST manipulation, multi-LLM orchestration
✓Ships fast — 87 passing tests, full documentation, production-ready architecture
✓Identified this pain from YC Fall 2026 Requests for Startups (Harsha Gaddipati)
🏆 Why solo works here

ApiPatch is a pure engineering product with a clear distribution moat: proactive PRs on open-source repos. The founder can execute the entire strategy alone with API credits. A co-founder search is underway for GTM and enterprise sales.
