  description: "Xquik is an independent third-party service. Not affiliated with X Corp. \"Twitter\" and \"X\" are trademarks of X Corp. Look up tweets, users, and X trends. Search tweets, check follow relationships, download media, and monitor accounts. 33 paid-read endpoints accept prepaid credits without a subscription. 7 fixed-price lookups also accept direct MPP payments. Write and automation endpoints require an API key or OAuth 2.1 bearer token.\n\n## Xquik SDKs\n\nStainless generates each SDK from this OpenAPI schema.

  x-guidance: '## Common tasks


    **Find a tweet** - GET /x/tweets/{id} with a numeric tweet ID. Returns full tweet data: text, author, metrics (likes, retweets, replies, views), media URLs, and creation timestamp. Cost: $0.00015 per lookup.


    **Search tweets** - GET /x/tweets/search?q={query}&limit={n}. Supports X search operators, structured filters like fromUser, mediaType, minFaves, hashtags, and verifiedOnly, plus exact lookup for a pasted Tweet ID or X status URL. Plain from:user date windows are optimized for timeline completeness. Returns up to 200 tweets per page with cursor-based pagination. Cost: $0.00015 per tweet returned.


    **Find a user** - GET /x/users/{id} where {id} is a numeric user ID or @username. Returns profile data: name, bio, follower/following counts, verification status, join date. Cost: $0.00015 per lookup.


    **Check if A follows B** - GET /x/followers/check?source={a}&target={b} where source and target are usernames, @usernames, or X or Twitter profile URLs. Cost: $0.00075.


    **Get trending topics** - GET /trends?woeid={region}&count={n}. WOEID 1 = worldwide, 23424977 = US, 23424975 = UK, 23424969 = Turkey. Cost: $0.00045.


    **Download media** - POST /x/media/download with {"tweetIds": ["123", "456"]} body. Returns download URLs for images and videos. Cost: 1 credit per fresh tweet processed with media; cached repeat downloads are free.


    **Read an article** - GET /x/articles/{tweetId} for long-form X Articles. Returns full article HTML, cover image, and metadata. Cost: $0.00075.


    ## Pagination


    Default v1 responses keep their existing pagination fields for compatibility. Platform list endpoints return `hasMore` and `nextCursor`; X data endpoints return `has_next_page` and `next_cursor`. Send `xquik-api-contract: 2026-04-29` to receive the unified best-practice fields `has_more` and `next_cursor`. Pass the cursor back as `?cursor={cursor}`; legacy `?after={cursor}` still works. Dynamic-priced endpoints charge per item returned, not per request.


    ## Authentication


    Eligible paid read endpoints accept accountless prepaid credit wallets. Fixed-price lookups also accept direct MPP payments. Media downloads, write endpoints, and automation features require authentication. Send an Xquik API key through `x-api-key`, `Xquik-Api-Key`, or `Authorization: Bearer xq_...`. Send an OAuth 2.1 access token through `Authorization: Bearer`.


    ## Best-Practice Response Contract


    v1 keeps its original response contract by default so existing integrations do not break. Send `xquik-api-contract: 2026-04-29` to opt in to the best-practice contract: snake_case response fields, Unix timestamps in seconds, structured error objects, `has_more` and `next_cursor` pagination fields, `object` resource identifiers, and prefixed IDs where available. Dependency failures that returned 502 in default v1 return 424 in the opt-in contract. Future major API versions should make this contract the default.'
