what callers paid
Access was read off the card rather than seen on the wire: inferred: the handshake, the tool list and a call without arguments went through with no key and no payment asked; no tool was run
Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.
trust_score_query reads unknown 19h ago
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.

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

Check the current state of an escrow (funded, released, disputed, expired, etc.)
{ "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 }arguments 14 linestrust_gate reads unknown never probed
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 call BEFORE escrow_create or safe_pay.

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.

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 safe_pay's trust-based amount limits

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.
{ "type": "object", "$schema": "http://json-schema.org/draft-07/schema#", "required": [ "seller", "amount_usdc", "service_url" ], "properties": { "seller": { "type": "string", "description": "Ethereum address of the seller/service provider" }, "amount_usdc": { "type": "number", "maximum": 100, "minimum": 0.1, "description": "Amount in USDC (e.g., 5.00 for $5)" }, "service_url": { "type": "string", "description": "URL or identifier of the service being purchased (used for tracking)" }, "timelock_minutes": { "type": "number", "default": 30, "maximum": 43200, "minimum": 5, "description": "Minutes until escrow expires and auto-refunds (default: 30)" } }, "additionalProperties": false }arguments 33 linesescrow_dispute changes data unknown never probed
Flag a problem with delivery — PayCrow's key differentiator. Locks escrowed funds and triggers arbiter review. Unlike other escrow services that say 'no disputes, no chargebacks', PayCrow has real on-chain dispute resolution. Use when service was not delivered or quality was unacceptable.
{ "type": "object", "$schema": "http://json-schema.org/draft-07/schema#", "required": [ "escrow_id", "reason" ], "properties": { "reason": { "type": "string", "description": "Brief description of the problem for the arbiter" }, "escrow_id": { "type": "string", "description": "The escrow ID to dispute" } }, "additionalProperties": false }arguments 19 linesrate_service changes data unknown never probed
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.
{ "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 }arguments 21 linessafe_pay moves money unknown never probed
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, payment capped at $5 - Unknown/caution → BLOCKED — will not send funds This is the recommended tool for paying any agent. If you need manual control, use x402_protected_call instead.

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.
Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.
- Sign any request with an ed25519 key — that binds it:
GET /api/v1/me, thenPOST /api/v1/passport. - Prove it is yours. Easiest: put
brick-blue-key=<your key>in your MCP server's instructions — or a DNS TXT record / a file on the domain. - Ask the hub to check:
POST /api/v1/passport/claim-endpointwith this listing's idb4d85361301e48d5.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/b4d85361301e48d5/claim.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.
An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.
MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.
Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
