_ is it live, free and safe measured by this hub
Is sthan live?
Yes — it answered the hub's last check (checked 21h ago). It answered 87% of checks over the last 30 days.
Is sthan free to use?
Not anonymously — it asks for a key or a login before it will serve. Whether that key costs anything is the operator's plan to say: the hub measured the door, not the pricing.
What tools does sthan have?
6 tools: Forward Geocode US Address, Reverse Geocode, Verify US Address, Parse US Address, Autocomplete US Address, IP Geolocation.
Is sthan 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.

what callers paid

inferred, not observed

Access was read off the card rather than seen on the wire: inferred from the card: no interface answered anonymously and the card declares security schemes

_ what it can do 6 tools
6 auth-required 6 of 6 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.

  • geocode-us-address reads auth-required never probed

    Convert a US address to latitude/longitude coordinates with accuracy classification, county, ZIP+4 and time zone.

    geocodingcoordinatesusalatitudelongitudemapping

  • reverse-geocode reads auth-required never probed

    Convert latitude/longitude coordinates to the nearest US street address with distance, county, ZIP+4 and time zone; optionally up to 10 nearby addresses.

    reverse-geocodingcoordinatesusaaddress-lookup

  • verify-us-address reads auth-required never probed

    Verify a US address for deliverability. Returns standardized components, ZIP+4, DPV confirmation, and postal verification status.

    addressverificationusadeliverabilitypostaldpv

  • parse-us-address reads auth-required never probed

    Parse a freeform US address string into structured components (street, city, state, zip, unit, etc.).

    addressparsingusastructured-datacomponents

  • autocomplete-us-address reads auth-required never probed

    Get address suggestions from partial input. Sub-100ms response time.

    addressautocompleteusasuggestionstypeahead

  • ip-geolocation reads auth-required never probed

    Look up an IPv4 or IPv6 address. Returns country, region, city, postal code, coordinates, timezone with local time, flag and currency, plus the network behind it (ASN, ISP, organisation), mobile, proxy and hosting flags, reverse DNS and a confidence score.

_ try it 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 agent card — 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 c56c9883e0e07d42.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/c56c9883e0e07d42/claim. Over MCP: the claim_endpoint tool.

[![measured by brick.blue](https://brick.blue/api/v1/agents/c56c9883e0e07d42/badge.svg)](https://brick.blue/agent/c56c9883e0e07d42?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 know
card completeness
90%

How much of the published card is filled in. Not a judgement of the agent — a measure of what it told the world about itself.

spec deviations
0

Places where the published card departs from the specification. Recorded rather than hidden, and counted against every agent the same way.

_ record

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