ontario-protocol
Registry code: 14ff1bfa426c3719
Ontario Protocol: x402 discovery and pre-payment verification for agent commerce. The default catalog supports buyers and endpoint providers: route, find, verify, decide, build a provider launch payload for free, or publish a service profile only when ontario_purchase_router returns paid_recommended. Free tools cost 0 USDC. Paid tools return x402 payment requirements (USDC on Base) when called without payment. The full catalog is at /mcp/full.

- Is ontario-protocol live?
- Yes — it answered the hub's last check (checked 51m ago). It answered 100% of checks over the last 30 days.
- Is ontario-protocol free to use?
- Yes — the hub reached it with no key and no payment.
- What tools does ontario-protocol have?
- 20 tools: ontario_find-api, ontario_base-balances, ontario_base-tx-check, ontario_base-gas, ontario_task_fit, x402_readiness_verify, bazaar_buyer_intent_gap, find_x402_tool, ….
- Is ontario-protocol safe to connect?
- The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Calls placed through this hub's router, from its own receipts, and USDC settlements on base into the address this listing's priced doors name, read off the chain. Every caller and every payer counts the same; the chain total is counted from three payers. The address stands behind 8 doors on this origin, so the chain figures are the operator's. How it is counted.

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.

Free deterministic routing of one public task to Ontario's free and paid tools. Returns the matching tool and a decision (free_only, run_free_preflight, or paid_recommended with the tool's price, network and budget check). Natural endpoint-verification tasks route to the free readiness verifier, with the optional 0.002 USDC settlement-backed receipt disclosed. Provider jobs such as publishing, registering, or making an x402 endpoint discoverable route to the self-serve 0.50 USDC publication product and its free validator. Paid reads it can recommend: ontario_find-api (a live-checked paid API for a task), ontario_base-balances (Base wallet balances), ontario_base-tx-check (whether a Base transaction settled) and ontario_base-gas (current Base gas prices). Existing paid profiles route to the 0.10 USDC evidence refresh and its free refresh validator. Empty calls return task examples instead of guessing a purchase. This tool never invokes another tool, signs a payload, or spends funds.

Free provider listing preflight for the 0.50 USDC Ontario launch passport.

Submits a public directory listing for an agent the caller owns. Payload validation is free; payment does not guarantee approval, traffic, ranking, or safety. [PAID: 0.10 USDC via x402 on Base. Two-step flow: a call without payment returns MCP PaymentRequired; the retry carries the signed PaymentPayload in params._meta['x402/payment']. The legacy _x402_payment base64 argument is also supported. Signing happens in the caller's wallet.]

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 id14ff1bfa426c3719.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/14ff1bfa426c3719/claim.
Over MCP: the claim_endpoint tool.

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.
