# XCROP — X/Twitter Data Intelligence API

> Real-time X (Twitter) data API platform for developers. 39 endpoints covering user profiles, tweets, search, followers/following, trending topics, interaction checks (verify retweet/reply/quote/follow — for airdrop & giveaway campaigns), and a Write API (post, reply, like, retweet, follow). Credit-based pricing, up to 50% cheaper than alternatives, free Starter tier with full access to every endpoint. Authentication via API key as a Bearer token. Cursor-based pagination. Official SDKs for JavaScript/TypeScript, Python, and Go.

## Key facts
- Base URL: https://xcrop.io/api/v2
- Auth: HTTP header `Authorization: Bearer xc_live_...` (get a key from the dashboard)
- Endpoint groups: Users (profile, followers, followers-ids, following, search, batch), Tweets (lookup, search, batch, replies, quotes), Interaction Check (check-retweet, check-reply, check-quote, check-follow, check-qualified-account, check-qualified-name), Write API (create tweet, reply, quote, like, retweet, follow — requires a connected X account), Trending, Lists, Communities
- Pagination: cursor-based — pass `next_cursor` from a response's `meta` object to fetch the next page
- Credits per call by data type: tweet 15, profile 18, follower 1 per result, interaction check 50, write action 100 (minimum 10 credits/call)
- Rate limits (requests/minute): Starter 10, Basic 30, Pro 60, Pay-as-you-go 30. Up to 1,000 results per request on every plan — paginate with the cursor for more (the bulk followers-ids endpoint returns up to 5,000 IDs per call)
- Plans differ only by monthly credits, rate limit, and credit price — never by which endpoints you can call. Every plan (including free Starter) can call all 39 endpoints.
