Measured tools (15)

• get_transcript read-only

  Fetch the full transcript of a YouTube video URL or ID as plain text, timestamped segments, SRT or VTT, optionally in a chosen or translated language. Use when the user asks to summarize, quote, search, or analyze a YouTube video, since the model cannot watch video. Takes one video per call. Returns one result with title, channel, language, whether captions are auto-generated, whether it fell back to another language, text and segments; a video without captions or one YouTube blocks comes back as status "error" with a code and retryable flag.

  Parameters:

  • video (required) — string — YouTube video URL (watch, youtu.be, shorts, embed, live) or 11-character video ID
  • format — string — segments = timestamped JSON plus text (default), text = plain text only, srt/vtt = subtitle file
  • languages — array — Language codes in priority order, e.g. ["en", "pt-BR"]; a code also matches its regional variants. Defaults to ["en"]
  • translateTo — string — Translate the transcript into this language code when YouTube offers it
  • fallbackToAnyLanguage — boolean — When none of the languages exist, return the video's original-language transcript (languageFallback: true) instead of an error. Defaults to true

Use when the user asks who is hiring, what roles a company has open, or to find remote or engineering roles at a named company. Optional filters: keyword, titleKeywords, excludeTitleKeywords, location, remote, department, employmentTypes, postedSince, postedWithinDays, withSalary. Returns normalized jobs (title, department, locations with ISO country codes, remote, workplace type, compensation, description, apply URL, dates); a board that cannot be read comes back as a type "error" record.

  Parameters:

  • companies (required) — array — Careers page URLs, "ats:slug" tokens or company names and domains, e.g. ["greenhouse:airbnb", "https://jobs.lever.co/spotify", "https://nvidia.wd5.myworkdayjobs.com/NVIDIAExternalCareerSite", "stripe.com"]

  • keyword — string — Keep jobs whose title or description mentions every word of this text
  • location — string — Keep jobs whose location text or city contains this, or whose country matches this name or ISO code
  • maxItems — integer — Cap on jobs returned in total across all companies
  • department — string — Keep jobs in a department matching this text
  • withSalary — boolean — Keep only jobs that publish a salary figure when true
  • postedSince — string — ISO date; keep jobs posted or updated on or after it

  • postedWithinDays — integer — Keep jobs posted or updated in the last N days
  • maxJobsPerCompany — integer — Cap on jobs returned per company after filtering (default 1000)
  • includeDescription — boolean — Workday, SmartRecruiters and BambooHR need one extra request per job for the full text; false skips it for a faster list
  • excludeTitleKeywords — array — Drop jobs whose title contains any of these phrases, e.g. ["senior", "intern"]

• get_app_reviews read-only

  Fetch app metadata and recent user reviews for a Google Play or iOS App Store app by store URL, Apple numeric id or Google Play package name, filtered by country, language, date and sort order. Use when the user wants to know what customers complain about or praise. Returns one app row (title, developer, rating, rating count, version) followed by review rows (rating, text, date, app version, helpful votes, developer reply). Apple's public reviews feed is sometimes empty; the app then returns its metadata plus an error row with code "unavailable" instead of reviews. Reviewer identity is never included.

  Parameters:

  • apps (required) — array — App Store or Google Play URLs, Apple numeric ids (id310633997) or Play package names (com.spotify.music)
  • sort — string — Review order. Defaults to newest
  • countries — array — Two-letter country codes. Defaults to ["us"]
  • languages — array — Google Play language codes. Defaults to ["en"]
  • sinceDate — string — ISO date; only reviews on or after it
  • maxReviewsPerApp — integer — Reviews per app, country and language. Default 100, 0 returns app metadata only

• read_x_post read-only

  Read public X (Twitter) posts from x.com or twitter.com URLs or post ids, through X's documented oEmbed endpoint (publish.x.com/oembed), with no login and no key. Use when the user shares a link to a post and wants what it says, who wrote it, the day it went up and its language. Each post row has text, author (handle, name), createdAt (YYYY-MM-DD), lang, the links in the text and hasMedia. X cuts posts longer than 280 characters in the embed and ends them with an ellipsis. The embed carries no media files, quoted post, like or view counts, replies or thread, so this tool cannot return them. A post X will not embed (deleted, protected, age-restricted, suspended author) comes back as a type "error" row with code unavailable, never partial data. Reads only the posts asked for; no timelines, search or profiles.

  Parameters:

  • posts (required) — array — Post URLs or numeric ids, e.g. ["https://x.com/jack/status/20", "20"]
