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.
