tools/list structure, inputSchema validity, and a functional smoke test — the components of the 0-100 score.
Tools the server advertised in the latest measurement — measured, not catalog-claimed.
serpWeb 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=n
paramsserp_batchBulk 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'}
paramsserp_multiMulti-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'}
paramsserp_readWeb search plus page reading in one call: answer with sources. Runs a web search, scrapes the top results, and returns the ranked search results together with each page's content as clean LLM-ready markdown, so an agent gets the SERP AND the underlying text without a second round of scrape calls. 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 para
paramsscrapeScrape any web page to clean markdown. A keyless web scraper that converts a single URL into LLM-ready markdown plus structured metadata (title, headings, links, word count), so an agent can read a page without running a browser. A per-call alternative to Firecrawl's scrape endpoint, with no API key and no account. Single page per call, not a site crawler. [$0.03/call]. Params — url: page URL to scrape; maxChars: markdown cap Example params: {'url': 'https://example.com'}
paramstrendGoogle Trends interest over time for a keyword. Returns Google Trends search interest as a dated series indexed 0-100: weekly points across the default past 12 months, daily points for 30- and 90-day windows, and windows from the past hour back to 2004, with optional country targeting. For keyword trend analysis, search demand seasonality, and SEO keyword research. [$0.05/call]. Params — keyword: the search term to chart; geo: ISO-3166 alpha-2 country code, e.g. US, GB, DE, JP (213 countries supported); omit for worldwide; timeframe: time window. Each response reports its own bucket size in `granularity`: past_30_days and past_90_days return a daily series, past_12_months and past_5_years weekly, windows under a day hourly (2004_present|past_12_months|past_30_days|past_4_hours|past_5_years
paramsrelated_queriesGoogle Trends related queries for a keyword. Returns the searches people run alongside a keyword in a given country: top queries scored 0-100 relative to each other, and rising queries with their percentage growth.

Each response reports its own bucket size in `granularity`: past_30_days and past_90_days return a daily series, past_12_months and past_5_years weekly, windows under a day hourly (2004_present|past_12_months|past_30_days|past_4_hours|past_5_years|past_7_days|past_90_days|past_day|past_hour) Example params: {
paramsinterest_by_regionGoogle Trends interest by region for a keyword. Returns the subregional breakdown of Google Trends search interest inside a country - by state, province, or region - each ranked 0-100 relative to the strongest region. For regional demand mapping, geo targeting, and finding where a keyword over-indexes before spending on it. [$0.03/call]. Params — keyword: the search term; geo: ISO-3166 alpha-2 country code, e.g. US, GB, DE, JP (213 countries supported); timeframe: time window. Each response reports its own bucket size in `granularity`: past_30_days and past_90_days return a daily series, past_12_months and past_5_years weekly, windows under a day hourly (2004_present|past_12_months|past_30_days|past_4_hours|past_5_years|past_7_days|past_90_days|past_day|past_hour) Example params: {'keyword
paramsrelated_topicsGoogle Trends related topics for a keyword.

paramsdomain_infoDomain WHOIS and DNS lookup. Registrar, creation and expiry dates, nameservers, and full DNS records (A, AAAA, MX, NS, TXT, CNAME) for a domain. [$0.02/call]. Params — domain: string Example params: {'domain': 'example.com'}
paramsdns_propagationDNS propagation checker. Compares a DNS record across public resolvers (Google, Cloudflare, Quad9, OpenDNS) to spot propagation lag or split-horizon answers. [$0.03/call]. Params — domain: string; record_type: string (A|AAAA|CNAME|MX|NS|TXT) Example params: {'domain': 'example.com', 'record_type': 'A'}
paramsEach block is one measurement round. Green: working response. Amber: responded but the server was returning errors (5xx). Red: no response at all.
Each cell is one probe run. Faded cells are incomplete probes — one leg did not answer, so the era is inconclusive.
The two probe legs separately: modern server/discover and legacy initialize.
Derived by comparing consecutive probes — changes in era, protocol version, build and reachability.
