Sourcelane

Twitter (X) stats API

Get the numbers behind any X account, not just the follower count. Pass usernames and get engagement rate, average and median likes, average views, tweets per week, reply and retweet share, top hashtags and top tweets — plus follower quality and similar accounts to benchmark against.

From $0.10 per result · no API key · failed calls refunded

Works with

What you get

  • Engagement rate and views-to-followers ratio
  • Average likes, retweets, replies, quotes and views
  • Tweets per week and content mix
  • Top tweets and hashtags
  • Followers, following, total tweets and account age
  • Fake-follower audit and similar accounts

Just ask your AI

“Compare the engagement rate of @stripe, @vercel and @supabase over their last 100 tweets.”

“Find 20 accounts similar to @levelsio and rank them by engagement rate.”

Connectors behind it

Your AI picks the right one for the question. Each is priced per result and refunded if it fails.

Use the Twitter stats API from Claude, ChatGPT or Cursor

Pick your tool and connect in under a minute. Then just ask — for example: “Compare the engagement rate of @stripe, @vercel and @supabase over their last 100 tweets.”

Connect Claude

Web, desktop and mobile. One click, then confirm.

  1. 1Click Add to Claude — claude.ai opens with Sourcelane filled in
  2. 2Click Continue to confirm — it then works in Claude desktop and mobile too
Manual setup (config files, REST, Python) +

Claude Code

Adds the Sourcelane MCP server with your key as a header.

terminal
claude mcp add --transport http sourcelane https://api.usesourcelane.com/mcp \
  --header "Authorization: Bearer sl_live_your_agent_key"

Claude Desktop (config file)

Alternative to the connector URL: add to claude_desktop_config.json, then restart Claude.

claude_desktop_config.json
{
  "mcpServers": {
    "sourcelane": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-remote",
        "https://api.usesourcelane.com/mcp",
        "--header",
        "Authorization:${AUTH_HEADER}"
      ],
      "env": {
        "AUTH_HEADER": "Bearer sl_live_your_agent_key"
      }
    }
  }
}

Cursor & Windsurf

Add to ~/.cursor/mcp.json (or Windsurf's mcp_config.json).

mcp.json
{
  "mcpServers": {
    "sourcelane": {
      "url": "https://api.usesourcelane.com/mcp",
      "headers": {
        "Authorization": "Bearer sl_live_your_agent_key"
      }
    }
  }
}

VS Code

Save as .vscode/mcp.json. VS Code prompts for your key once.

.vscode/mcp.json
{
  "servers": {
    "sourcelane": {
      "type": "http",
      "url": "https://api.usesourcelane.com/mcp",
      "headers": {
        "Authorization": "Bearer ${input:sourcelane-key}"
      }
    }
  },
  "inputs": [
    {
      "type": "promptString",
      "id": "sourcelane-key",
      "description": "Sourcelane agent key",
      "password": true
    }
  ]
}

ChatGPT Custom GPT (Actions)

Create a GPT → Actions → Import from URL, then Authentication: API Key, Bearer.

OpenAPI schema URL
https://usesourcelane.com/openapi.json

REST

One POST. Pass maxResults to cap cost.

curl
curl -X POST https://api.usesourcelane.com/v1/call \
  -H "Authorization: Bearer sl_live_your_agent_key" \
  -H "Content-Type: application/json" \
  -d '{"listing":"x-influencer-analytics-scraper","params":{"usernames":["mkbhd"]},"maxResults":10}'

Python, LangChain, CrewAI, OpenAI Agents SDK…

Wrap the REST call as a tool, or point an MCP client at the endpoint.

python
import requests

res = requests.post(
    "https://api.usesourcelane.com/v1/call",
    headers={"Authorization": "Bearer sl_live_your_agent_key"},
    json={
        "listing": "x-influencer-analytics-scraper",
        "params": {"usernames":["mkbhd"]},
        "maxResults": 10,
    },
    timeout=300,
)
body = res.json()
print(body["receipt"]["chargedMicros"], "micro-USD for", body["receipt"]["results"], "results")
print(body["data"])

Twitter stats API — FAQ

How many tweets are analysed?+

You choose — set how many recent tweets to analyse per account.

Do I need X API access?+

No. There's no X developer account or paid API tier on your side.

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.
