  • X’s &amp;, &lt; & &gt; arrive as &, < & >
  • displayTextRange & entity indices count the decoded text

  • That covers likes, replies, reposts, quotes, bookmarks & views
  • X’s own repost counts were 0, apart from reposts & a smaller view count
  • Tweet search reads since:, until:, sinceDate & untilDate as UTC days
  • x.com uses your time zone, so its day edges can differ

  • Followers come newest first. x.com puts some promoted followers first
  • A reply read with sinceTime & scope=direct stops X’s newest-first view once it is past your window

  • Tweet search drops an unmatched quote, which X refuses, & returns rows
  • searchedQuery then shows the query X searched
  • A search X refuses returns 424 search_unavailable, never an empty page
  • User Tweets, user replies, quotes & List Tweets list keywords, place, placeCountry, pointRadius, boundingBox & advancedQuery
  • User Tweets, user replies & quotes also list listId, and Tweet search lists keywords
  • A user timeline with a search filter such as keywords filters every Tweet, not only older ones
  • max_results sets the page size wherever limit & count do
  • maxItems, max_items & per_page set it too
  • Tweet search queryType takes any case & the aliases type, search_type, product, category & section
  • Photos, Videos & Media search Latest with that media type. People & Lists answer 400 with the route to use

  • Those are cardName, source, excludeSource, geocode, near, within, safe & news
  • List Tweets & direct replies take the legacy after cursor alias on every page
  • Community search applies withinTime
  • Events prefer monitorId to monitor_id. A monitor filter without a usable ID lists no events
  • A cursor ignores parameters its route doesn’t read, so dropping one keeps it
  • A post X never published fails as x_post_not_sent. You pay nothing & can post again
  • Writes X never confirms end expired & charge nothing. Check your X account before you retry
  • X’s 500, 504 & 408 after the send keep a write pending_confirmation as x_write_ambiguous
  • Pending answers say retryable: false
  • Before the send, those give x_transient_error & are safe to retry, not x_write_failed
  • X refusals that state a reason return 422 x_rejected. They used to return 500 x_write_failed
  • X’s refusal of an image’s size returns 422 x_image_invalid
  • Avatar & banner uploads take images up to 15 MiB. Xquik fits them to X’s limits
  • Post images over 5 MiB shrink to fit. GIFs & videos go to X unchanged
  • An unreadable image returns 415 unsupported_media_type
  • An image Xquik can’t shrink enough returns 413 media_too_large
  • OpenAPI lists 413 & 415 on media writes, plus 3 media error codes
  • Post & user path params take URLs & handles. See path IDs
  • Post params take a post ID or an x.com or twitter.com post URL
  • User params take a user ID, a username with or without @, or a profile URL
  • Writes look up a username first. An unknown username returns 422 x_target_not_found
  • Other input returns 400 invalid_tweet_id or 400 invalid_user_id
  • GET /x/users/{id} returns invalid_user_id where it returned invalid_username
  • Writes X refuses outright return 422 x_rejected & charge nothing
  • POST /x/communities returns 422 x_account_feature_required when the account can’t create communities
  • Both used to look like unconfirmed writes
  • MCP execute takes paths with or without /api/v1, such as /x/users/nasa/follow
  • GET /x/users/{id}/tweets & GET /x/users/{id}/replies now list sinceTime, untilTime & mode
  • Both routes already applied them. sinceTime keeps its exact second & untilTime drops it
  • A time without an offset reads as UTC on every route that takes these bounds
  • An offset whose + arrived unencoded, such as 21:20:41 02:00, reads as +02:00
  • Community Tweets, List Tweets, thread & batch users now list every filter they applied
  • Quotes list includeReplies, and bookmark folders list cursor

  • Replies to a post that is unavailable on X return 422 x_reply_target_unavailable
  • Some used to return 500 x_write_failed
  • Xquik sends nothing & charges nothing. Check the post on x.com or reply to another post
  • GET /draws, GET /drafts & GET /events return 400 invalid_input for an unknown cursor
  • Before, they returned the first page again
  • Send the last nextCursor you received, or omit the cursor to start over
  • An empty cursor still returns the first page
  • Replies, quotes, retweeters & thread of a post X does not have return 404 tweet_not_found
  • They used to return 200 with an empty page. GET /x/tweets/{id} already returned this 404
  • Only an empty first page checks the post. A post without engagement still returns 200
  • A 404 costs no credits
  • Each account now gets 500 reads a second, up from 300
  • Writes still allow 120 a minute & deletes 60 a minute
  • 429 x_rate_limited messages now name the wait from Retry-After, such as about 15 minutes
  • Without a known wait, the message says to try again later
  • Writes X refuses as possibly automated return 422 x_automation_refused
  • They used to return 429 x_rate_limited
  • Waiting does not change X’s answer. Send the next request now with a new Idempotency-Key
  • If X keeps refusing, check the account on x.com. Vary your text or pace
  • These refusals cost nothing
  • 429 x_rate_limited now covers only X’s rate limits. Wait for Retry-After when present
  • GET /x/tweets/{id}/replies with sort=latest or sort=oldest sets orderPartial: true when some rows come from X views without date order
  • Rows stay sorted by date & keep the same status. Replies may be missing between them
  • Nothing marked such answers before. Retry later for a gap-free order
  • When X’s Recent view ends early or comes back signed out, Xquik reads the rest from X search’s Latest results
  • GET /x/tweets/{id}/replies applies sort on automatic pages too
  • Those pages used to list the newest replies first, whatever the sort
  • Without sort, automatic pages still list the newest first. Standard pages ignore sort
  • POST /draws reads every direct reply & retweeter X shows
  • It used to read X’s first page of replies & at most 2,000 retweeters
  • Entries are direct replies to the post. Replies to other replies no longer enter
  • A draw on a busy post takes about 1 minute. Keep the request open for 100 seconds
  • GET /x/tweets/{id}/retweeters no longer ends the list early when X refuses a page
  • Xquik reads that page again
  • POST /draws returns 424 when X stops the reply or repost read early
  • It used to draw from the entries read so far
  • Retry after replies_incomplete or retweeters_incomplete
  • draw_too_large means the post has more entries than 1 draw reads. Contact support
  • Xquik saves & charges nothing for these draws
  • Bookmark folder reads on accounts without X Premium return 424 bookmark_folders_unavailable
  • This covers GET /x/bookmarks/folders & GET /x/bookmarks?folderId=...
  • They used to return an empty list. The message says to upgrade on X or read all bookmarks
  • These answers cost nothing
  • Search Tweets returns 424 search_unavailable at once for filter:vine, filter:consumer_video, filter:pro_video, filter:news & retweets_of:
  • X no longer searches these. news=true gets the same answer
  • The message says what to change, such as the term to remove
  • A query X refuses as a whole also gets 424 search_unavailable, such as one over 512 characters
  • These answers cost nothing
  • Follower, following, verified follower, retweeter & user search pages take enrichProfiles=true
  • Each row then carries the full profile, with fields such as accountBasedIn
  • The x-xquik-profile-enrichment header counts the rows that carry it
  • Extractions of these rows take enrichProfiles & add the profile at enrichmentData.profile
  • The price per row stays the same
  • Complete-mode replies return 200 after reading a whole sinceTime or untilTime window
  • Replies outside the window no longer turn that answer into 424 replies_incomplete
  • Complete-mode replies add diagnostic.sourcesEnded
  • true means every source ended. X hides the other replies
  • A 424 replies_incomplete with sourcesEnded: true returns the same rows on retry
  • Its message says X hides the other replies instead of asking for a retry
  • Complete-mode replies find replies from new & small accounts more reliably
  • diagnostic.strategiesAttempted[].stopReason adds partial_view for a view that showed only part of a thread
  • Such a view keeps sourcesEnded false until the read holds every reply the post counts
  • withinTime now filters user Tweets, replies, media, likes & mentions
  • It also filters Tweet replies & quotes
  • Posts outside the window no longer come back or cost credits
  • Use a whole number & s, m, h or d, such as 90m or 7d

  • Another body with the same key returns 409 idempotency_conflict
  • A draw that fails its save or final charge stores nothing & charges nothing
  • The dashboard sends 1 key per draw, so a resubmit returns the saved draw
  • Webhook retries have no attempt limit. They continue until your endpoint returns 2xx
  • 410 Gone retries like any other failure
  • A failing endpoint gets 1 waiting delivery at a time, at least every 15 minutes
  • When that delivery succeeds, Xquik starts sending pending deliveries
  • Resume Webhook & isActive: true start sending waiting deliveries at once
  • Without them, a rejected delivery can wait up to 7 days after a fix
  • Only a paused or deleted webhook marks deliveries exhausted
  • Resume within 30 days of an event to receive its held delivery
  • Return 2xx for deliveries you skip. A rejected one can delay new ones up to 15 minutes
