_ is it live, free and safe measured by this hub
Is verza live?
Yes — it answered the hub's last check (checked 21m ago). It answered 100% of checks over the last 30 days.
Is verza free to use?
Yes — the hub reached it with no key and no payment.
What tools does verza have?
11 tools: IP address screening, VAT number validation, Bulk identifier validation, Business pre-screen, Risk score, CIPC enterprise number check, SA contact and identity validation, Domain age and registry status, ….
Is verza 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 also stands behind 3 other origins: the chain figures are the gateway's, not this listing's alone. How it is counted.

_ what it can do 11 tools
4 paid 7 never probed 4 of 11 classified

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.

  • domain-check 0.01 USDC paid never probed

    Domain age and registry status from RDAP via the IANA bootstrap. A South African .za name is refused. Also reports whether an address record and an MX record exist. Dates and status only. It does not confirm who owns or runs the domain. Also callable as /v1/domain-check/{domain}.

    domaincheckpaidget

  • site-audit 0.5 USDC paid never probed

    Audit one public http or https page: Lighthouse scores, DNS, SPF, DMARC, DKIM selectors, TLS, security headers and subdomains. Verza calls a render worker and does not fetch the page itself. An empty body is a 402 when the worker can run. A private or loopback host is HTTP 400 after payment is verified and is not settled. A busy or unreachable worker is HTTP 503 with Retry-After and is not settled.

  • id-validate 0.01 USDC paid never probed

    Structural validation of a South African identity number with safe decode: Luhn check digit, birth date, gender and citizenship segments (citizen or permanent resident). The structural step in KYC, KYB and customer onboarding or due diligence workflows: derive date of birth, age, gender and citizenship without storing the identity. Run it before a paid registry lookup rather than instead of one: a Home Affairs check is priced in rands per query, so screening structurally first means you never spend one on a number that could not have been issued. Stateless, never stored or logged (POPIA-conscious by construction). Confirms structure only, not registration with Home Affairs. Also callable as /v1/id-validate/{id}.

    idvalidatepaidget

  • loan-check 0.25 USDC paid never probed

    Independent lawfulness check of a South African credit agreement's interest rate against the National Credit Act (NCA) Regulation 42 maximum rate caps, the statutory interest rate cap that replaced the old usury limits: the maximum rate is fixed at the repo rate on the date the agreement was concluded. Covers every Reg 42 credit type including mortgage agreements, credit facilities, unsecured credit, short-term credit and developmental credit. Verdict, exact cap, excess and full workings, from daily-audited SARB and gazette data, for credit providers, compliance teams and the interest-rate limb of a reckless-lending or affordability review. Covers every agreement under the current Regulation 42 table (concluded 2016-05-06 or later). Also callable as /v1/loan-check/{credit_type}/{annual_rate_percent}/{date_concluded}.

  • ip-check unknown never probed

    Screen an IP address against the Tor exit list and published AWS, Google Cloud and Cloudflare ranges, and name the country and network from public registry data. It does not locate a person. VPN and proxy detection beyond Tor exits and known cloud ranges is not offered.

    ipcheckpaidpost

  • vat-validate unknown never probed

    Structural validation of a South African VAT registration number (VAT vendor number): 10 digits, leading 4, check digit. Use it to screen a supplier or customer VAT number before invoicing or claiming input VAT. Free. Confirms format only, not active SARS registration.

    vatvalidatefreeget

  • bulk-validate unknown never probed

    Validate up to 50 South African identifiers in one settled call: ID numbers, VAT numbers, or a mix. Batch screening of a customer or supplier list for structurally invalid South African identifiers, for onboarding, KYC and KYB compliance clean-ups. Same checks and same honest scope as the single endpoints, with a summary of how many passed. Cheaper than five individual ID checks and a single round trip instead of fifty.

    bulkvalidatepaidpost

  • business-verify unknown never probed

    Supplier pre-screen in one call: CIPC number format, VAT number format, domain age and email DNS. Structural and public DNS checks only. It does not confirm the company exists at CIPC, is VAT-registered at SARS, or holds a B-BBEE level.

    businessverifypaidpost

  • risk-score unknown never probed

    A points sum of named rules over a South African phone number, an email address, an ID number and an IP address. The rules and the points are published. The score is an input to a person, not a decision, and service must not be refused on this score alone.

    riskscorepaidpost

  • company-validate unknown never probed

    Decode a South African CIPC enterprise number (YYYY/NNNNNN/TT): registration year, sequence and entity type. Free. It confirms the number is well formed. It does not confirm the enterprise exists, is in business, or its name. CIPC offers no free machine-readable registry lookup. Also callable as /v1/company-validate/{reg}.

    companyvalidatefreeget

  • contact-validate unknown never probed

    Validate a South African phone number, an email address and an optional ID number in one call. Phone returns E.164, line type and the original network allocation, which is not the current network because the number may have been ported. Email checks syntax, MX, disposable and role flags, and does not confirm the mailbox exists. A phone-only request is one check and one charge.

_ try it over a2a 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.

  1. Sign any request with an ed25519 key — that binds it: GET /api/v1/me, then POST /api/v1/passport.
  2. 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.
  3. Ask the hub to check: POST /api/v1/passport/claim-endpoint with this listing's id 4a9d0ea2116ebc40.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/4a9d0ea2116ebc40/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.

_ how we knowoff the mcp door
card completeness
70%

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
0

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