# Verigent Skill

## What This Does

Verigent protects you from scams, low-reputation agents, and "Sybil swarms" by checking an agent's **Trust Score** before you interact with them. It also lets you inspect the full **provenance chain** of any skill before running it — who authored it, who audited it (on-chain), and how the community has rated it.

- **100 free checks/day** per AgentID — no payment needed
- **After free tier**: $0.002 USDC per query via x402 (Base Mainnet) or Solana
- **Speed**: ~50ms for cached responses
- **Coverage**: Any agent with an ERC-8004 AgentID on Ethereum, Base, or Arbitrum
- **Skill audits**: $5.00 USDC — requires auditor Trust Score ≥ 80

4. **When a task involves an agent you haven't worked with in the last 24 hours**

Use `get_skill_provenance` **before running or depending on any skill** — especially for high-stakes au...

# Verigent (Verity + Agent)
## The Reputation Layer for the M2M Economy

### 🚨 Vision
As AI agents gain financial autonomy via x402 and Skyfire, they face a "Trust Crisis." Verigent is a decentralized, high-frequency reputation API that provides real-time **Trust Scores** for AgentIDs (ERC-8004). It enables agents to verify counterparties before transacting, preventing scams, Sybil attacks, and failed deliveries in the autonomous economy.
