correctover 1.0.0

The correct version of failover — protocol-level contract validation with automatic failover for LLM APIs

Correctover SDK

The correct version of failover.

Because failover switches. Correctover verifies.

What It Does

Correctover is an embedded reliability runtime for LLM APIs. It provides:

• Contract Validation — Verify responses match expected schema, not just HTTP 200
• Automatic Failover — Switch providers when contracts are violated
• Drift Detection — Catch silent model substitutions and schema drift
• 6-Dimension Verification — Structure, schema, latency, cost, identity, integrity

Quick Start

pip install correctover

from correctover import Correctover

# Drop-in replacement for openai.OpenAI
client = Correctover(api_key="sk-xxx")
response = client.chat.completions.create(
    model="gpt-4o",
    messages=[{"role": "user", "content": "Hello!"}],
)

Why Correctover, Not Just Failover?

	Failover	Correctover
Switches provider?	✅	✅
Validates the response?	❌	✅
Detects silent model swap?	❌	✅
Catches schema drift?	❌	✅
Prevents cost overruns?	❌	✅

Failover switches. Correctover verifies.
