The REST API, with 70 endpoints, is recommended for high-throughput pipelines and background workers, while the MCP server provides 12 read-only tools for AI agents and ad-hoc queries through Claude Desktop, Cursor, or Codex. Both channels share the same API key and credit pool, with a flat cost of $0.15 per 1,000 tweets and no additional overhead for the MCP server beyond a ~50ms tool-call latency.", "body_md": "Decision guide for choosing between [TwitterAPI.io](https://twitterapi.io) REST endpoints and the hosted MCP server at `https://mcp.twitterapi.io/mcp`\n\n.\n\n- You're building a pipeline / cron job / background worker\n- You want full control over query params + retries + caching\n- You're integrating with an existing data stack (Postgres, ClickHouse, S3)\n- Your throughput is moderate to high (>10K tweets/day continuous)\n- You're collecting historical datasets for research / analytics\n\n- Your end-user is a human asking ad-hoc questions in Claude Desktop / Cursor / Codex\n- You're building an AI agent that needs Twitter context on demand\n- You don't want to maintain an SDK upgrade path\n- Your usage is sparse (a few tool calls per session, not continuous)\n- You want the model to decide\n*when*and*what*to query\n\nYes — they share the same API key + credit pool. Pattern:\n\n- REST pipeline ingests historical data into your warehouse\n- MCP server lets analysts ask questions about the same data through Claude\n- Same TwitterAPI.io key, same billing line, two integration paths\n\nSame per-tweet cost ($0.15 per 1K) regardless of channel. The MCP server adds no overhead; you pay only for tweets actually returned to the model.\n\n- REST: round-trip ~100-300ms median\n- MCP server: same network latency + ~50ms tool-call overhead\n- WebSocket stream: <500ms tweet-to-handler\n\n- REST:\n`X-API-Key`\n\nheader on each request - MCP server:\n`TWITTERAPI_IO_API_KEY`\n\nenvironment variable on the client side; never enters the model context - WebSocket: same\n`X-API-Key`\n\non upgrade request\n\nMCP exposes 12 read-only tools:\n`search_tweets`\n\n, `get_user_info`\n\n, `get_user_timeline`\n\n, `get_user_followers`\n\n, `get_user_following`\n\n, `get_tweet_by_id`\n\n, `get_replies`\n\n, `get_quotes`\n\n, `get_retweeters`\n\n, `search_users`\n\n, `get_trending_topics`\n\n, `get_tweet_metrics`\n\n.\n\nREST exposes ~70 endpoints — more granular control.
