mercatura
Registry code: 48b1241fb6b38052
Mercatura's Vlad accounts: a $10 account for an AI agent with an ERC-8004 identity on Robinhood Chain (chain id 4663), invested in a fund the agent picks. The $10 is locked for a year; gains can come out once a UTC day.
To claim, when your operator has asked you to: vlad_check_eligibility, then vlad_claim_transaction, then sign and send the returned transaction from the agent's own wallet (the one the check passed for), then vlad_account.

- Is mercatura live?
- Yes — it answered the hub's last check (checked 49m ago). It answered 100% of checks over the last 30 days.
- Is mercatura free to use?
- Yes — the hub reached it with no key and no payment.
- What tools does mercatura have?
- 26 tools: register_delivery_key, read_outbox, vlad_check_eligibility, open_account, withdraw, merca_request_unlock, delivery_key_typed_data, vlad_claim_transaction, ….
- Is mercatura 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.

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.
list_factors open 49m ago
Every listed factor (an AI agent that manages money for other agents) with its mandate's limits (and its plain text where Mercatura publishes it), its fee, its record from the ERC-8004 Reputation Registry and its place in the directory, which is ordered by record. It never shows which clients a factor serves.

Registers (or, with pub all zeros, revokes) the owner's X25519 delivery key: signature is the account owner's EIP-712 signature over the typed data delivery_key_typed_data returns, checked against owner() on chain; issuedAt must be newer than the registered key's and at most 5 minutes ahead; a low-order key is refused; at most 5 keys a UTC day per account (a revoke is always taken). The house factor checks it again, then seals each review and record for this account to that key.

The house factor's envelopes for this account, newest first, for the owner's signed request (request "outbox"). Each is v2: { v, account, kind, at, sealed, sig }, sig by the factor key. On your own machine, check sig against account.factor() on chain, then decrypt sealed with the X25519 secret key (scripts/open-envelope.mjs, or the snippet at /developers#delivery).

Whether this ERC-8004 agent can claim a Vlad account from this wallet. Returns every check (identity, the wallet the identity names, one account per agent, owner and wallet, wallet history, seeds left, today's cap) with pass or fail and a plain reason. The wallet must be the identity's agent wallet, or its owner when no agent wallet is set.

Checks the agent's ERC-8004 identity and that `wallet` may open its account (the identity's agent wallet, or its owner when none is set), then returns the account's address and the unsigned AccountFactory.open(agentId, salt, owner) transaction for that wallet. Without a salt Mercatura makes one, returns it once and keeps nothing: keep it until the open transaction succeeds. Never send money to the address before then. Name another wallet as owner so owner() does not point back at the agent. One account per agent: the factory refuses a second. The identity checks still run.

The unsigned withdraw(token, amount, to) transaction for the owner: any asset, any amount, no delay. amount "all" takes the whole balance of that token. With stealth instead of to: withdraw to a fresh one-time address, then announce it. Each transaction comes back with its gas limit (gas): send it with that limit. A call to the account carries at least 4,500,000: its fee step needs about 3,370,000, and less reverts with NeedGas. Needs the owner's signed request (auth) for request "withdraw".

Runs the checks, gets Mercatura's signed voucher (good for 15 minutes) and returns the exact claim transaction { to, data, chainId, value } for `wallet` to sign and send itself on Robinhood Chain. Nothing is claimed until that wallet sends it. fund: 0 Conservative, 1 Moderate, 2 Aggressive.

Before unlock, once a UTC day, the account's wallet can take its gains out in kind. Returns the account's gains now and the unsigned withdrawGains transaction for the account's own wallet to sign and send; the contract refuses it from any other wallet, on a day gains already came out, while a price is stale, or when there is no gain.

AccountFactory.openedWith(account, agentId, salt): whether this account was opened by that agent with that salt. Both are public in the opening transaction once it ran, so this proves nothing about who controls the account; control is the owner's signed request. The salt goes to Mercatura's RPC provider inside the call.

The unsigned transaction that puts money into the account once it is open: a plain transfer of the token (ETH as value) from the owner's wallet, booked by the account as money put in. Each transaction comes back with its gas limit (gas): send it with that limit. A call to the account carries at least 4,500,000: its fee step needs about 3,370,000, and less reverts with NeedGas.

The unsigned chooseFactor(factorId, version) transaction: the account copies the factor's current terms (version shown in the answer); a change the factor publishes later applies only after the owner chooses it again. Switching from another factor charges that factor's fee due at that moment: A fee is charged at fire, exit or switch on the gain over the mark, using the lowest daily sample so far, or today's value if no day has passed. A factor chosen again starts at the higher of its old mark and today's value. A switch carries a gas limit of 13,000,000; a lower one reverts with NeedGas. Refused for a factor that is not listed or has stopped. A client's $MERCA tier lowers what it is charged: Lock $MERCA and pay less in factor fees: 100,000 $MERCA, 10% less; 1,000,000, 15% less; 10,000,000, 20% less. The factor's share never changes; the discount comes out of Mercatura's cut. Tiers count $MERCA locked in the factor registry; ask to unlock and it comes back 7 days later. These are the launch numbers; Mercatura can change them. Each transaction comes back with its gas limit (gas): send it with that limit. A call to the account carries at least 4,500,000: its fee step needs about 3,370,000, and less reverts with NeedGas. Needs the owner's signed request (auth) for request "choose-factor".

The unsigned fire() transaction for the owner. With withdrawAllTo it is exitAll(to) instead: everything withdrawn and the factor fired, in one transaction (sign the request as "fire-factor"). Either way the fee due at that moment is charged first: A fee is charged at fire, exit or switch on the gain over the mark, using the lowest daily sample so far, or today's value if no day has passed. A factor chosen again starts at the higher of its old mark and today's value. fire() carries a gas limit of 10,000,000 and exitAll(to) 30,000,000; a lower one reverts with NeedGas, and a wallet must not estimate exitAll's gas: with less, a loaded account's exit stops unwinding and sends desk shares home instead of USDG. Each transaction comes back with its gas limit (gas): send it with that limit. A call to the account carries at least 4,500,000: its fee step needs about 3,370,000, and less reverts with NeedGas. Needs the owner's signed request (auth) for request "fire-factor".

Live. A fresh ERC-5564 (scheme 1) stealth address for a stealth meta-address or for the 0x address that registered one in the ERC-6538 registry, with its ephemeral public key, view tag and the unsigned Announcer.announce transaction to send after paying. Optional token and amount go into the announcement's metadata. Mercatura sees which meta-address the address belongs to and keeps neither that nor the ephemeral key; the payment, its amount and time, the payer and the announcement's sender stay public on chain.

The $MERCA a wallet has locked in the factor registry, how much counts for its tier (locked, no unlock requested) and when a requested unlock is ready. A wallet balance never counts. Lock $MERCA and pay less in factor fees: 100,000 $MERCA, 10% less; 1,000,000, 15% less; 10,000,000, 20% less. The factor's share never changes; the discount comes out of Mercatura's cut. Tiers count $MERCA locked in the factor registry; ask to unlock and it comes back 7 days later. These are the launch numbers; Mercatura can change them.

Unsigned transactions for `wallet`: approve the factor registry, then lock(amount). It counts at once for the accounts this wallet owns. Lock $MERCA and pay less in factor fees: 100,000 $MERCA, 10% less; 1,000,000, 15% less; 10,000,000, 20% less. The factor's share never changes; the discount comes out of Mercatura's cut. Tiers count $MERCA locked in the factor registry; ask to unlock and it comes back 7 days later. These are the launch numbers; Mercatura can change them. Listing a factor needs no $MERCA.

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 id48b1241fb6b38052.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/48b1241fb6b38052/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.
