Shield

Stop shipping hallucinations. One function call.

---

Built for developers shipping AI to production. Wrap any LLM output in shield() and get back a trust score, corrections, and verification receipts. Works with OpenAI, Anthropic, LLaMA, Mistral, Gemini -- any model, any framework.

from veroq import shield

result = shield("NVIDIA reported $22B in Q4 revenue, beating estimates by 12%.")

print(result.trust_score)     # 0.73
print(result.is_trusted)      # False
print(result.corrections)     # [{"claim": "...", "correction": "..."}]
print(result.verified_text)   # text with corrections inline

import { shield } from "@veroq/sdk";

const result = await shield("NVIDIA reported $22B in Q4 revenue, beating estimates by 12%.");

console.log(result.trustScore);    // 0.73
console.log(result.isTrusted);     // false
console.log(result.corrections);   // [{claim, correction, confidence}]

What Shield Does

1. Extracts verifiable claims from any LLM text
2. Verifies each claim against real-time evidence (web, financial data, public records)
3. Returns a trust score (0-1), corrections for anything wrong, and permanent verification receipts

Every verification produces a receipt -- a permanent, shareable proof that a claim was checked.

Install

pip install veroq          # Python
npm install @veroq/sdk     # TypeScript / Node.js

Examples

Wrap any LLM call

from veroq import shield
import openai

response = openai.chat.completions.create(
    model="gpt-5.4",
    messages=[{"role": "user", "content": "What was NVIDIA's Q4 2024 revenue?"}],
)

verified = shield(response.choices[0].message.content)

if not verified.is_trusted:
    print(f"Found {verified.claims_contradicted} incorrect claims")
    for c in verified.corrections:
        print(f"  Wrong: {c['claim']}")
        print(f"  Fixed: {c['correction']}")

Block untrusted responses

from veroq import shield

# Raises VeroqError if any claim is contradicted
result = shield(llm_output, block_if_untrusted=True)

Zero-config middleware

from veroq.middleware import openai_shield

# Every OpenAI response is automatically verified
client = openai_shield(openai.OpenAI())
response = client.chat.completions.create(model="gpt-5.4", messages=[...])
# response now has .veroq_shield attached

High-volume caching

from veroq import CachedShield

cached = CachedShield(max_cache=1000, ttl_seconds=3600)
result = cached("NVIDIA reported $22B in Q4 revenue")   # API call
result = cached("NVIDIA reported $22B in Q4 revenue")   # instant, 0 credits
print(cached.stats())  # {'hits': 1, 'misses': 1, 'hit_rate': 0.5, 'size': 1}

CI/CD -- verify AI outputs before deploy

# .github/workflows/shield.yml
- uses: veroq/shield-action@v1
  with:
    api-key: ${{ secrets.VEROQ_API_KEY }}
    prompts: tests/prompts.json
    threshold: 0.7

TypeScript

import { shield, CachedShield } from "@veroq/sdk";

// Basic
const result = await shield("NVIDIA's Q4 revenue exceeded $22B");

// With options
const result = await shield(llmOutput, {
  source: "gpt-5.4",
  agentId: "my-bot",
  blockIfUntrusted: true,
});

// Cached for high volume
const cached = new CachedShield({ maxCache: 1000 });
const r1 = await cached.shield("NVIDIA reported $22B");  // API call
const r2 = await cached.shield("NVIDIA reported $22B");  // instant

How It Works

Your LLM output
      |
      v
  [ Extract claims ]     "NVIDIA Q4 revenue was $22B"
      |                   "Estimates were $20.4B"
      v
  [ Verify each claim ]  web search + financial data + public records
      |
      v
  [ Return ShieldResult ]
      |
      +-- trust_score: 0.73
      +-- corrections: [{claim, correction}]
      +-- receipt_ids: ["vr_abc123"]  (permanent, shareable proof)

Shield uses VeroQ's verification engine under the hood: real-time web search, financial data providers, and cross-reference analysis. No fine-tuned models or vibes -- just evidence.

Part of VeroQ

Shield is the fastest way to start with VeroQ -- the verified intelligence platform for AI agents. When you're ready for more:

• Verified Swarm -- 5-agent pipeline that auto-verifies every step
• Agent Memory -- persistent per-agent knowledge that gets smarter over time
• Agent Runtime -- vertical kits for finance, legal, research, compliance
• 62 MCP Tools -- full Model Context Protocol integration
• Verification Receipts -- permanent, shareable proof of every verification

Built with Shield

Production reference implementations that use Shield-style verification end-to-end:

• TradingAgents-Pro -- 18-agent multi-agent trading framework with per-claim fact-checking, bias detection, and forward predictions with invalidation criteria. Apache-2.0 fork of TradingAgents.
