Twitter (X) followers API
Export who follows an account — and who it follows — with each user's bio, location, verification status and follower count. Use it for lead lists, audience research or finding the influencers inside a competitor's audience.
From $0.001 per user · no API key · failed calls refunded
What you get
- Followers or following list of any public profile
- Bio, location and verification for each user
- Follower counts for each user
- Verified-only followers
Just ask your AI
“Export @stripe's verified followers and list the 20 with the biggest audiences.”
“Who among @a16z's followers is a founder based in London?”
Connectors behind it
Your AI picks the right one for the question. Each is priced per result and refunded if it fails.

Is there a follower limit?+
Set maxItems per call and page through larger accounts. You pay per user returned.
Do I need a X (Twitter) API key or developer account?+
No. Sourcelane runs the connectors for you. You top up a balance with a card, create an agent key, and your agent calls the connector — there is no X (Twitter) app review, OAuth setup or rate-limit juggling on your side.
Which AI tools can use it?+
Anything that speaks MCP (Claude Desktop, Claude Code, Cursor, VS Code, Windsurf) can connect to the Sourcelane MCP server with one config block. ChatGPT can use it through a Custom GPT Action, and any agent framework can call the REST endpoint directly.
Can I stop an agent from overspending?+
Yes. Every agent key has its own per-call cap, daily and monthly limits, an optional lifetime budget, an allowlist of connectors, and a kill switch.
