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 â the only escrow service with real dispute resolution on Base.

escrow_dispute
Flag a problem with delivery â 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.

escrow_release
Confirm delivery and release escrowed USDC to the seller. Only call this when you've verified the service/product was delivered correctly.

escrow_status
Check the current state of an escrow (funded, released, disputed, expired, etc.)
入力スキーマ
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['escrow_id'], 'properties': {'escrow_id': {'type': 'string', 'description': 'The escrow ID to check'}}, 'additionalProperties': False}
rate_service
Rate a completed escrow. After escrow_release, rate the seller's service quality (1-5 stars).
This builds the reputation data that makes PayCrow's trust scores meaningful over time.
Both sides can rate: buyer rates seller's service quality, seller rates buyer's conduct.
Ratings are on-chain and permanent â they feed directly into trust scoring.
入力スキーマ
{'type': 'object', '$schema': 'http://json-schema.org/draft-07/schema#', 'required': ['escrow_id', 'stars'], 'properties': {'stars': {'type': 'integer', 'maximum': 5, 'minimum': 1, 'description': 'Rating 1-5 stars (1=terrible, 5=excellent)'}, 'escrow_id': {'type': 'string', 'description': 'The escrow ID to rate (must be in Released state)'}}, 'additionalProperties': False}
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 â Set protection level â Create escrow â Call API â Verify â Auto-release or auto-dispute.
Protection levels (automatic):
- High trust agent â 15min timelock, proceed normally
- Moderate trust â 60min timelock, payment capped at $25
- Low trust â 4hr timelock, payment capped at $5
- Unknown/caution â BLOCKED â will not send funds
This is the recommended tool for paying any agent. If you need manual control, use x402_protected_call instead.

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 â shorter timelock, proceed with confidence
- Low trust â longer timelock, smaller amounts recommended
- Caution â don't proceed, or use maximum protection
This is the tool to call BEFORE escrow_create or safe_pay.

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.

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.

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 â 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 safe_pay's trust-based amount limits
