Web Search & Data API
Registry code: e9557ced3661751c
Web search and web data for AI agents. Run a web or news search and get ranked title/URL/snippet results (serp); search and read the top hits as markdown in one call (serp_read); run many queries at once (serp_batch) or fuse several engines (serp_multi); turn any URL into clean markdown (scrape). Measure demand with Google Trends — interest over time (trend), rising and top related queries (related_queries) and topics (related_topics), and interest by region (interest_by_region). Look up structured facts: geocoding (geocode), WHOIS/registration (domain_info), DNS records (dns_propagation),…

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

Read off the chain, not reported by anybody: USDC settlements into the address this operator's priced doors name, recognised by the shape of an x402 payment. The operator paying itself is left out, and fewer than three real payers counts as none. This address also stands behind 1 other origin: the figure is the gateway's, not this listing's alone. How it is counted.

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.

Academic and scientific paper search API. Search research papers and scholarly literature across arXiv, PubMed, OpenAlex, Crossref, and Semantic Scholar in one call, deduplicated into a ranked result set: title, authors, year, venue, abstract, citation count, DOI, and direct PDF link. Query by keyword or restrict to one source; filter by year range; sort by relevance, recency, or citations. Keyless. [$0.02/call].

Author and researcher profile search. An author name returns matching researchers with current affiliation, publication count, total citations, h-index and i10-index, and their most-cited papers — for author lookup, disambiguation, and citation-metrics. Keyless via OpenAlex. [$0.02/call]. Params — name: author name to search; maxItems: 1-25 candidate authors; top_works: top papers per author (0-25) Example params: {'name': 'Yoshua Bengio', 'maxItems': 3}
{ "type": "object", "title": "_toolArguments", "properties": { "params": { "anyOf": [ { "type": "object", "additionalProperties": true }, { "type": "null" } ], "title": "Params", "default": null } } }arguments 19 linesrelated_papers reads 0.03 USDC paid never probed
Literature review and related-paper discovery. Given a seed paper (arXiv id, DOI, or OpenAlex id) or a topic query, returns semantically similar and recommended scholarly papers to expand a reading list or systematic review, via Semantic Scholar recommendations with an OpenAlex related-works fallback. Keyless. [$0.03/call]. Params — id: paper arXiv id, DOI, or OpenAlex id; doi: alias for id (DOI form); q: query (alternative to id — relevance search); maxItems: 1-50 Example params: {'doi': '10.48550/arXiv.1706.03762', 'maxItems': 10}
{ "type": "object", "title": "_toolArguments", "properties": { "params": { "anyOf": [ { "type": "object", "additionalProperties": true }, { "type": "null" } ], "title": "Params", "default": null } } }arguments 19 linescve reads 0.01 USDC paid never probed
CVE vulnerability lookup. Returns security vulnerability records by CVE id or keyword from the NIST National Vulnerability Database and GitHub Security Advisories, each with CVSS score, severity, CWE weakness class, affected products, and references, filterable by severity and source. For vulnerability triage and dependency risk checks. Keyless. [$0.01/call].

Web search results (SERP). Keyless web search returning ranked title, URL, and snippet for a query — with locale/region targeting, freshness filters (past day, week, month, year), pagination, a news mode that adds publish date and source, and selectable backend engine (auto rotation, or pin Brave, Yahoo, or Yandex). [$0.05/call]. Params — q: search query; num_results: max results, cap 25; region: locale, e.g. us-en, uk-en, de-de; timelimit: restrict to past day/week/month/year (d|w|m|y); safesearch: string (on|moderate|off); page: result page (pagination); mode: web results or recent news (news adds date+source per item). the news index is narrow, so a long or highly specific news query that matches nothing falls through to web rather than returning empty; those items carry requestedMode=news and servedBy=web (web|news); engine: search backend: auto (recommended - rotates engines and falls back on blocks) or pin one of yahoo, yandex (web mode); news mode supports bing. when set, each result carries an 'engine' field; if the pinned engine returns nothing, auto serves instead and results also carry 'requestedEngine' Example params: {'q': 'best python web scraping library', 'num_results': 10}
{ "type": "object", "title": "_toolArguments", "properties": { "params": { "anyOf": [ { "type": "object", "additionalProperties": true }, { "type": "null" } ], "title": "Params", "default": null } } }arguments 19 linesserp_batch reads 0.1 USDC paid never probed
Bulk web search: up to 5 search queries in a single call, each returning ranked title, URL, and snippet, with the same locale, freshness, and news filters as the single-query web search. One paid call instead of five for research fan-out. [$0.10/call]. Params — queries: up to 5 search queries separated by '|'; num_results: max results per query, cap 25; region: locale, e.g. us-en, uk-en, de-de; timelimit: restrict to past day/week/month/year (d|w|m|y); safesearch: string (on|moderate|off); mode: string (web|news); engine: search backend: auto (recommended) or yahoo/yandex (web); bing (news) Example params: {'queries': 'python asyncio tutorial|rust tokio tutorial'}

Multi-engine web search (metasearch). One search query fanned out across 2-3 search engines (Brave, Yahoo, Yandex) with results deduplicated by URL and merged by reciprocal-rank fusion: consensus ranking across engines instead of one engine's bias, with per-engine rank attribution on every result. [$0.05/call]. Params — q: search query; engines: comma list of 2-3 engines: yahoo, yandex (web mode). news mode has a single live engine (bing), so multi-engine is web-only; num_results: max results per engine, cap 25; region: locale, e.g. us-en, uk-en, de-de; timelimit: restrict to past day/week/month/year (d|w|m|y); safesearch: string (on|moderate|off); mode: string (web|news) Example params: {'q': 'best vector database 2026', 'engines': 'yahoo,yandex'}

Per-page fetch errors are reported honestly per URL. [$0.08/call]. Params — q: search query; fetch_top: how many top results to fetch and extract, cap 5; maxChars: max markdown chars per fetched page; num_results: ranked results to return, cap 25; region: locale, e.g. us-en, uk-en, de-de; timelimit: restrict to past day/week/month/year (d|w|m|y); safesearch: string (on|moderate|off); mode: string (web|news); engine: search backend: auto (recommended) or yahoo/yandex (web); bing (news) Example params: {'q': 'how does x402 payment protocol work', 'fetch_top': 3}

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.
[](https://brick.blue/agent/e9557ced3661751c)
The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.
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.
