TwitterAPI.io

TwitterAPI.io is a third-party API for public social data from X, built for developers and AI agents. It is independent of X Corp and needs no X developer account: a user signs in, copies an API key and starts calling. It lists 75 endpoints for searching posts and reading feeds, profiles and followers, plus write actions such as posting and liking, with WebSocket and webhook delivery for live data. An official MCP server gives Claude, Cursor and other MCP clients 12 read-only tools, as a hosted server at mcp.twitterapi.io or an npm package run with npx.

Prices are in US dollars and billed per result returned, with a minimum of $0.00015 per call and no monthly fee. Tweets cost $0.15 per 1,000, profiles from $0.01 per 1,000, followers and following from $0.01 per 1,000, and follower IDs from $0.0045 per 1,000. New accounts get up to $1 in free credits that expire after 31 days. Optional subscriptions add credit bonuses, and on the Business subscription every $1 buys 1.90 times the credits.

Agents that need general web search and extraction can also look at Tavily. Teams that need scraping across many sites can look at Thordata, and teams that want one key for many paid data endpoints can look at looot.
