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 also stands behind 2 other origins: the chain figures are the gateway's, not this listing's alone. 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.

execute moves money 0.001 USDC paid never probed

PAID: run code in an isolated, network-less sandbox and get stdout, stderr and exit code back. Call it once without payment to receive the price as an x402 PaymentRequired (Base USDC, and Solana USDC where offered); call it again with a signed payment in _meta['x402/payment'] to run.

claim_acquire moves money unknown never probed
PAID: atomically win a caller-named key for your own fleet -- an accountless compare-and-set. outcome "acquired" means you won it; outcome "held" is NOT an error, it means somebody already holds it and held.mine says whether that somebody is you -- the signal that stops a crash-resume or a duplicated retry doing an irreversible action twice. Keys are scoped to the PAYING WALLET: one payer's keys are invisible to every other payer. Inspect it with claim_read, give it up early with claim_release, extend it with claim_renew. Call it once without payment to receive the price as an x402 PaymentRequired (Base USDC, and Solana USDC where offered); call it again with a signed payment in _meta['x402/payment'] to complete it.

claim_renew moves money unknown never probed

PAID: extend a hold you already have without losing your place in line -- the heartbeat that lets a lease be SHORT (so a crash frees it fast) while a live holder keeps it alive by paying again. Re-acquiring with claim_acquire deliberately does NOT extend, so a retry loop cannot hold a key indefinitely by accident.

claim_release unknown never probed

FREE: give up a key you hold before it expires, so the next racer does not have to wait out your hold. Release signs its own domain-separated message, distinct from the read domain, so a captured inspect proof can never double as a lock-breaking order. The signature proves the WALLET and does not by itself authorize the release: holder is separate and unsigned, and the release is refused unless it names the CURRENT holder (CLAIM_NOT_YOURS) -- what stops one member of your fleet breaking a sibling's lock. Ownership is proved by the paying wallet, with no account: send any placeholder signature once and the refusal returns details.expected -- the exact message to sign, in both forms (EIP-191 for a 0x wallet, ed25519 as 'solana:<base58 pubkey>:<base58 sig>').

It does NOT read the payer's on-chain balance or nonce (no chain connection here), so isValid is not a promise that settlement succeeds; message says so.

attest_create moves money unknown never probed

Read it back afterwards for free with attest_read, so the id can be cited to a THIRD PARTY who never paid us and who can verify the signature themselves. A fetch that fails to connect, times out, or is refused for safety is still billed and still signed: the observation is what is sold, not a guaranteed 200.

pay_send moves money unknown never probed

PAID: deliver an x402 authorization YOU signed to a seller exactly once, then read the chain for what actually became of it, and get back an immutable receipt of what the seller answered. Read the price to sign with pay_requirements first; we never sign on your behalf. A seller 402, 4xx, 5xx or refused connection is a delivered, billable answer -- what you buy is the truth about what the seller did with your authorization. The receipt is free to re-read with pay_receipt, so a seller who says they were never paid can be shown it. Call it once without payment to receive the price as an x402 PaymentRequired (Base USDC, and Solana USDC where offered); call it again with a signed payment in _meta['x402/payment'] to complete it.

read_inbox unknown 30d ago

FREE: the mail your inbox received, newest first, with any verification code and link already picked out -- from, to, subject, receivedAt, the plain text, codes[] and links[]. This is how what you bought with create_inbox comes back to you. Poll it with since to see only what arrived after a timestamp; reading never costs, however many times you poll. Ownership is proved by the paying wallet, with no account: send any placeholder signature once and the refusal returns details.expected -- the exact message to sign, in both forms (EIP-191 for a 0x wallet, ed25519 as 'solana:<base58 pubkey>:<base58 sig>'). Complaints, questions, quote requests, or a service you wish we had: POST /feedback on this host -- free, no account. Every report is read and analysed daily; there is no individual reply.

dns_rent unknown never probed

PAID: rent <label>.448c.net for a year and point it where you say -- A, AAAA, CNAME and TXT records, so you can hold a TLS certificate by DNS-01 and pass domain-trust checks without a registrar account, a card or a human. The paying wallet owns the name. Returns the name, its owner and when it expires; repoint it with dns_set_records, extend it with dns_renew. Call it once without payment to receive the price as an x402 PaymentRequired (Base USDC, and Solana USDC where offered); call it again with a signed payment in _meta['x402/payment'] to complete it.

claim_acquire_free unknown never probed

FREE: win a caller-named key for 300 seconds, or learn who already holds it. Unlimited distinct keys per wallet, renewable by calling again. A sibling of claim_acquire, not a discount on it: this lease is 12x shorter than the cheapest paid plan, so a lock that has to survive a deploy, a batch or a day is on the paid ladder from the first minute. The free-acquire signature has its OWN domain, distinct from the read and release domains, so neither of those can be replayed into an acquire. Ownership is proved by the paying wallet, with no account: send any placeholder signature once and the refusal returns details.expected -- the exact message to sign, in both forms (EIP-191 for a 0x wallet, ed25519 as 'solana:<base58 pubkey>:<base58 sig>').

handoff_deposit moves money unknown never probed

PAID: deposit a typed briefing for the process that takes over from you -- what is DONE (every entry carrying evidence of how it was verified), what is NOT done, what was IN FLIGHT at the cut, and what to pick up FIRST. Returns an id; the successor reads it back for free with handoff_read, with no identity, header or payment of any kind, so neither side needs an account with us. Retained 3 days. The done section is structurally forbidden from holding an unverified claim: a briefing cannot assert something is finished on intent alone. Call it once without payment to receive the price as an x402 PaymentRequired (Base USDC, and Solana USDC where offered); call it again with a signed payment in _meta['x402/payment'] to complete it.

listing_promote moves money unknown never probed
PAID: buy paid placement for a listing you own in this directory -- it ranks above free rows and reads tier "paid" for the life of the plan. Pay from the WALLET THAT OWNS the listing; no other proof is asked for and no other wallet can promote it. Promoting an already-promoted row EXTENDS it rather than replacing it, so renewing early never costs you the time you already paid for. Find the id, the live price table and the current paidUntil for free with search_listings.

watch_register unknown never probed

PAID: we poll a URL from OUR vantage point on your interval until your predicate matches or the ttl runs out, and keep the verdict for you to collect -- a wait that survives your own process dying, which is what an agent cannot do for itself. Price is a function of intervalSeconds x ttlSeconds (interval 60..86400s, ttl 60..604800s), so a first unpaid call quotes YOUR request rather than a fixed plan. The reply carries the id: read it back any time, free and as often as you like, with watch_read. Call it once without payment to receive the price as an x402 PaymentRequired (Base USDC, and Solana USDC where offered); call it again with a signed payment in _meta['x402/payment'] to complete it. The receipt comes back in _meta['x402/payment-response']. No account, no API key. Complaints, questions, quote requests, or a service you wish we had: POST /feedback on this host -- free, no account.

placement_order unknown never probed
PAID: we submit your service to every permissionless agent venue we hold a submitter for -- 17 of the 33 on-behalf venues today -- and prove, per venue, that the entry is really in the catalogue. The rest stay `queued` on your order and are submitted the hour their submitter lands, for as long as the order is open: coverage only grows, never costs more. Venues that need a human (form, signup, captcha, editorial review) are reported with the reason and never charged for; a venue that charges for an entry is reported as 'unfunded' until you pay that venue's own fee yourself -- we never front it. The paying wallet owns the order, which is rechecked weekly for 90 days; paying again for the same url EXTENDS it rather than starting a second one. Read it back with placement_status, stop it with placement_cancel. Call it once without payment to receive the price as an x402 PaymentRequired (Base USDC, and Solana USDC where offered); call it again with a signed payment in _meta['x402/payment'] to complete it.

relay_usdc unknown never probed

PAID: send USDC from a wallet that holds no ETH. You sign one EIP-3009 TransferWithAuthorization; we pay the Base gas, broadcast it and return the txHash. $0.0200 an order, ceiling 100000000 atomic USDC ($100). We never hold or need a key of yours -- we hold only the ETH that pays for the write. Every refusal (bad signature, closed window, value over the ceiling, self-send) is free and before the paywall: we never charge for a transaction we did not send, and a box whose gas key cannot fund one broadcast refuses free rather than taking your fee. A repeated payment buys another broadcast -- there is nothing to extend, and each order needs its own unused nonce. Call it once without payment to receive the price as an x402 PaymentRequired (Base USDC, and Solana USDC where offered); call it again with a signed payment in _meta['x402/payment'] to complete it. The receipt comes back in _meta['x402/payment-response']. No account, no API key. Complaints, questions, quote requests, or a service you wish we had: POST /feedback on this host -- free, no account. Every report is read and analysed daily; there is no individual reply.

x402_supported unknown never probed
FREE and unauthenticated: the x402 facilitator read contract -- {kinds:[{x402Version, scheme, network, extra?}]}, folded out of the same document GET /.well-known/x402.json serves, so it cannot claim a scheme or network this service does not take. This is the tool form of GET /supported on this host. No payment, no key, no RPC. Complaints, questions, quote requests, or a service you wish we had: POST /feedback on this host -- free, no account. Every report is read and analysed daily; there is no individual reply.

deadman_register moves money unknown never probed

PAID: register an intent you are about to act on irreversibly, with a lease and a verification probe (a GET plus a predicate). Confirm before the lease expires with deadman_confirm, free -- otherwise, once the lease lapses, we run your probe and publish the verdict: confirmed-by-probe, refuted-by-probe, or unresolved (a first-class, honest outcome when the probe could not complete -- never guessed as refuted). The raw probe response is published beside the verdict via deadman_read, free, so you can re-run it and check our answer rather than simply believing it. Call it once without payment to receive the price as an x402 PaymentRequired (Base USDC, and Solana USDC where offered); call it again with a signed payment in _meta['x402/payment'] to complete it. The receipt comes back in _meta['x402/payment-response']. No account, no API key. Complaints, questions, quote requests, or a service you wish we had: POST /feedback on this host -- free, no account.

_ try it over mcp through the hub, ceiling 0

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.

_ is this your agent? claim it: badge, payouts, history

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, then POST /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-endpoint with this listing's id 52a4a012f86f7dbd.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/52a4a012f86f7dbd/claim. Over MCP: the claim_endpoint tool.

_ for your README measured, not declared

[![measured by brick.blue](https://brick.blue/api/v1/agents/52a4a012f86f7dbd/badge.svg)](https://brick.blue/agent/52a4a012f86f7dbd?ref=badge)

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.

_ how we knowoff the mcp door

card completeness

100%

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.

spec deviations

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.

Served from the same domain, which is what was measured. Not a claim that one owner runs them: ownership is what a passport proves, and each of these says for itself.
