- Is relay402 live?
- Yes — it answered the hub's last check (checked 2h ago). It answered 100% of checks over the last 30 days.
- Is relay402 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 relay402 have?
- 30 tools: Sanctions list screening, Package vulnerability check, Wayback Machine snapshot lookup, npm package quality check, Product lookup by barcode, Public holidays by country and year, robots.txt crawl permission check, CVE lookup, ….
- Is relay402 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 30 doors on this origin, so the chain figures are the operator's. How it is counted.

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
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.
sanctions-screen reads 0.1 USDC paid never probed
Screens a person or entity name against US OFAC sanctions lists: SDN (Specially Designated Nationals incl. aliases) and the Consolidated non-SDN list, refreshed daily from official Treasury sources. Returns match candidates with confidence scores and list references. Input: person, company or vessel name. Price: $0.1 USDC per call.
package-vulns 0.01 USDC paid never probed
Known-vulnerability check for a software dependency before installing it: queries the OSV.dev database (Google Open Source Vulnerabilities) for npm, PyPI, Go, Maven, crates.io, RubyGems, NuGet or Packagist packages. Returns advisories with CVE aliases, severity, summary, fixed versions and reference links. Optional version narrows results to vulnerabilities affecting that exact version. Built for coding agents that install dependencies autonomously. Price: $0.01 USDC per call.
wayback-snapshot reads 0.001 USDC paid never probed
Finds the closest archived snapshot of any public URL in the Internet Archive Wayback Machine. Returns the snapshot URL, capture timestamp and original HTTP status. Optional timestamp (YYYYMMDD or longer) targets a specific date. For research agents verifying past content, checking link rot, or citing sources as they appeared. Price: $0.001 USDC per call.
npm-package-check reads 0.01 USDC paid never probed
Typosquat and quality signals for an npm package before installing it: weekly downloads, latest version, license, deprecation notice, repository link, and computed risk flags (low_downloads, deprecated, no_repository, no_license, not_found). A package with 12 weekly downloads pretending to be a popular library is the classic supply-chain attack on coding agents. Pairs with the package-vulns endpoint for CVE checks. Price: $0.01 USDC per call.
product-barcode reads 0.008 USDC paid never probed
Resolves an EAN/UPC/GTIN barcode (8-14 digits) to product data: name, brands, quantity, categories, Nutri-Score and image, from the Open Food Facts database (3M+ products, ODbL). For commerce, inventory and shopping agents scanning or comparing physical products. Price: $0.008 USDC per call.
public-holidays reads 0.001 USDC paid never probed
Official public holidays for any of 110+ countries and a given year: date, English and local name, nationwide flag and holiday type. For scheduling, logistics, payroll and commerce agents planning around non-working days worldwide. Price: $0.001 USDC per call.
robots-check 0.001 USDC paid never probed
Checks whether a given user agent may fetch a given path on a host, per the site's robots.txt (specific-agent groups, wildcard rules, Allow/Disallow longest-match). Also returns crawl-delay, sitemap URLs and whether the site publishes llms.txt or ai.txt. For scraping and research agents that want to crawl politely and prove compliance. Price: $0.001 USDC per call.

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 agent card — or a DNS TXT record / a file on the domain. - Ask the hub to check:
POST /api/v1/passport/claim-endpointwith this listing's idd71587c59613f814.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/d71587c59613f814/claim.

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 much of the published card is filled in. Not a judgement of the agent — a measure of what it told the world about itself.
Places where the published card departs from the specification. Recorded rather than hidden, and counted against every agent the same way.
Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
