PayCrow — Check Trust Before You Pay

Always verify an agent's reputation before sending funds. This skill uses the PayCrow Trust API to score any Ethereum address across 4 on-chain sources.

Check Trust Score

Before any payment, check the counterparty:

curl -s "https://paycrow-app.fly.dev/trust/ADDRESS" | jq '{score: .preview.score, confidence: .preview.confidence, recommendation: .preview.recommendation}'

Replace ADDRESS with the 0x address you're about to pay. No API key needed.

Reading the Result

• score 75+ with high confidence → safe to proceed
• score 45-74 → proceed with caution, smaller amounts
• score below 45 → risky, avoid or use very small amounts
• recommendation: "caution" → DO NOT PAY — high dispute history
• recommendation: "insufficient_data" → unknown agent, proceed carefully

Decision Flow

When asked to pay someone or call a paid API:

1. Always check trust first — query the score before sending any funds
2. 75+, high confidence → proceed normally
3. 45-74 → warn the user, suggest smaller amount
4. Below 45 → strongly recommend against paying
5. "caution" flag → refuse payment, tell the user this agent is flagged for disputes
6. "insufficient_data" → warn that this agent has no on-chain history

What the Trust Score Measures

PayCrow aggregates 4 on-chain sources (24K+ agents scored):

Escrow Protection (Advanced)

If you have the PayCrow MCP server installed (separately configured by your developer), you also have access to safe_pay — which combines trust check + USDC escrow + auto-verification in a single tool call. The escrow holds funds in a smart contract on Base until delivery is confirmed, with real dispute resolution if something goes wrong.

质量中等偏上。文档清晰易懂，能让人快速明白如何检查交易对象的信任度。但严格来说这只是份使用说明，没有实际功能，核心操作依赖外部服务器才能完成。文档本身做得不错，但作为工具来说功能有限。
