- Yes — it answered the hub's last check (checked 8h ago). It answered 99% of checks over the last 30 days.
- Is Neptyune Agent APIs free to use?
- Yes — the hub reached it with no key and no payment.
- What tools does Neptyune Agent APIs have?
- 17 tools: URL expansion, TLS certificate details, Feed parser, Summarise, Mail provider detection, Link extraction, Robots and sitemap, Prompt compression, ….
- Is Neptyune Agent APIs 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
Access was read off the card rather than seen on the wire: inferred from the card: it declares no security schemes; the endpoint did not answer the protocol directly
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.
compress reads 0.003 USDC paid never probed
Strips filler, hedging and restated context from text while preserving every fact and instruction. Agents pay per token, so compressing a long context typically costs far less than the tokens it saves. Returns the compressed text with before and after token estimates.
lead-score reads 0.006 USDC paid never probed
Scores a company domain as an outbound prospect: combines domain age, email authentication health, mail provider, detected stack and site signals into a 0-100 score with the reasoning. One call instead of five.
company-intel reads 0.02 USDC paid never probed
Structured company profile from a website URL: what they do, industry, likely tool stack, estimated team size and the internal requests their team plausibly receives. Built for lead research, qualification and personalised outbound.
domain-age reads 0.004 USDC paid never probed
Registration date, age in days, expiry and registrar from WHOIS. Useful for scoring whether a domain is newly registered (a common spam and fraud signal).
email-auth reads 0.003 USDC paid never probed
SPF, DKIM and DMARC for a domain, parsed, with a pass/fail verdict and the specific misconfigurations. Tells you whether mail from this domain will authenticate.
email-verify reads 0.004 USDC paid never probed
Validates an address: syntax, domain resolves, MX present, disposable-provider detection, role-account detection, free-provider detection, and a deliverability verdict. Market rate is about $0.008 per check.
page-meta reads 0.003 USDC paid never probed
Title, description, canonical URL, OpenGraph and Twitter card tags, favicon and any JSON-LD structured data from a URL.
tech-detect reads 0.004 USDC paid never probed
Detects the stack a site runs on: CMS, framework, analytics, ecommerce, hosting and CDN, from response headers and page markup.
dns-records reads 0.002 USDC paid never probed
All DNS records for a domain (A, AAAA, MX, TXT, NS, CNAME, SOA) in one call.
page-extract reads 0.006 USDC paid never probed
Clean readable text from any URL with scripts, styles and markup stripped. The primitive an agent needs before it can reason about a page. Market rate for scraping is roughly $0.83 to $1.66 per thousand pages.
url-expand reads unknown never probed
Follows a shortened or tracking URL through every redirect and returns the full chain plus the final destination. Lets an agent see where a link really goes before visiting it.
ssl-info reads unknown never probed
Certificate issuer, subject, validity window, days until expiry and alternative names for any host.
rss-parse reads unknown never probed
Parses an RSS or Atom feed into structured items with title, link, date and summary. Also finds the feed automatically if given a site URL.
summarize reads unknown never probed
Turns long text into a summary at the length you ask for. Send raw text or a URL and it fetches the page first.
mail-provider reads unknown never probed
Identifies who hosts a domain's email (Google Workspace, Microsoft 365, Zoho, Proton, self-hosted and others) from its MX records.
links-extract reads unknown never probed
Every link on a page, split into internal and external, deduplicated and resolved to absolute URLs. Also surfaces any email addresses and social profiles found.
robots-check reads unknown never probed
Fetches robots.txt, tells you whether a given path and user-agent may be crawled, and lists declared sitemaps. Lets an agent check crawl permission before scraping.
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 id34921e36547b6660.
Every step, filled in for this listing: https://brick.blue/api/v1/agents/34921e36547b6660/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 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.
