Tools: trust_gate trust_score_query trust_onchain_quick escrow_create escrow_release escrow_dispute escrow_status rate_service safe_pay x402_protected_call
trust_gate | Should you pay this agent? Check before sending money. Returns a go/no-go decision with recommended escrow protection parameters.
Unlike other trust services, PayCrow ties trust directly to escrow protection:
- High trust → shorter timelock, proceed with confidence
- Low trust → longer timelock, smaller amounts recommended
- Caution → don't proceed, or use maximum protection
This is the tool to params: address*, intended_amount_usdc |
trust_score_query | Full trust score breakdown for an agent address. Aggregates 4 on-chain sources: PayCrow escrow history, ERC-8004 agent identity, Moltbook social karma, and Base chain activity. Returns 0-100 score with per-source details. For a quick go/no-go decision, use trust_gate instead. params: address* |
trust_onchain_quick | Quick on-chain reputation check using only the PayCrow Reputation contract. Free, no API keys needed. Use trust_score_query for the full composite score. params: address* |
escrow_create | Create a USDC escrow with built-in dispute resolution. Funds are locked on-chain until delivery is confirmed (release) or a problem is flagged (dispute). If disputed, an arbiter reviews and rules — the only escrow service with real dispute resolution on Base. params: seller*, amount_usdc*, timelock_minutes, service_url* |
escrow_release | Confirm delivery and release escrowed USDC to the seller. Only call this when you've verified the service/product was delivered correctly. params: escrow_id* |
escrow_dispute | Flag a problem with delivery — PayCrow's key differentiator. Locks escrowed funds and triggers arbiter review. Unlike other escrow services that say 'no disputes, no chargebacks', PayCrow has real on-chain dispute resolution. Use when service was not delivered or quality was unacceptable. params: escrow_id*, reason* |
escrow_status | Check the current state of an escrow (funded, released, disputed, expired, etc.) params: escrow_id* |
rate_service | Rate a completed escrow. After escrow_release, rate the seller's service quality (1-5 stars).
This builds the reputation data that makes PayCrow's trust scores meaningful over time.
Both sides can rate: buyer rates seller's service quality, seller rates buyer's conduct.
Ratings are on-chain and permanent — they feed directly into trust scoring. params: escrow_id*, stars* |
safe_pay | The smart way to pay an agent. Checks their trust score first, then auto-configures escrow protection based on risk.
Flow: Check trust → Set protection level → Create escrow → Call API → Verify → Auto-release or auto-dispute.
Protection levels (automatic):
- High trust agent → 15min timelock, proceed normally
- Moderate trust → 60min timelock, payment capped at $25
- Low trust → 4hr timelock, pa params: url*, seller_address*, amount_usdc*, method, headers, body |
x402_protected_call | Make an HTTP API call with manual escrow protection. Full control over verification and timelock parameters.
For most payments, use safe_pay instead — it auto-configures protection based on seller trust.
Use x402_protected_call when you need:
- Custom JSON Schema verification (not just "valid JSON + 2xx")
- Hash-lock verification (exact response match)
- Specific timelock durations
- To override params: url*, method, headers, body, seller_address*, amount_usdc*, timelock_minutes, verification_strategy, verification_data* |
