ChatterAPI

ChatterAPI skill and MCP setup

Live Reddit and X (Twitter) data for Claude, Cursor, Codex and any other MCP client, plus a Claude skill that teaches the agent to use it without burning through credits.

ChatterAPI gives you one API key for both platforms. Search posts, comments and tweets, read full threads, look up users and subreddits, find leads and track brand mentions. You can call it over REST (https://api.chatterapi.com/v1) or connect the hosted MCP server (https://api.chatterapi.com/mcp) and let your agent pick the tools.

This repo has three things:

• SKILL.md: a Claude skill for four jobs (find leads, listen for mentions, research communities, look up people) with budget rules, so the agent asks before an expensive run.
• examples/mcp/: copy-paste MCP configs for Claude Code, Claude Desktop, Cursor, Windsurf and Codex.
• examples/rest/: the same search in curl, Python and JavaScript.

Install

1. Get a key. Sign up at chatterapi.com/signup with Google. You get 100 free credits without a card. Keep the key in an environment variable:

export CHATTERAPI_KEY="ca_live_..."

2. Connect the MCP server. For Claude Code:

claude mcp add --transport http chatterapi https://api.chatterapi.com/mcp \  --header "Authorization: Bearer $CHATTERAPI_KEY"

Other clients are in examples/mcp/. The MCP server page has the full setup for each client and how to check it worked.

3. Add the skill.

npx skills add Amplifyx-Labs/chatterapi-skill

Or copy SKILL.md into ~/.claude/skills/chatterapi/.

Then ask your agent something like "find people on Reddit and X asking for a CRM recommendation this week" or "what does r/SaaS allow for self-promotion?"

Use it over REST

curl -s "https://api.chatterapi.com/v1/reddit/search?q=crm&limit=10" \  -H "Authorization: Bearer $CHATTERAPI_KEY"

Every response has this shape, with a cursor for the next page (pass it back as cursor) and the credits the call cost:

{  "data": [{ "id": "1wdihhj", "title": "What CRM should a small business use?", "...": "..." }],  "page": { "nextCursor": "AX-vad045wfn…", "hasMore": true },  "credits": { "charged": 2, "remaining": 98 },  "requestId": "req_..."}

Python and JavaScript versions are in examples/rest/.

If you use Reddit and X data for growth rather than building on it, these may save you time:

• XAutoDM: cold DM outreach on X, for when you've found the right people and want to reach them.
• Grow With Reddit: free subreddit-aware tools for writing posts that fit a community's rules.
• Subreddit Marketing: a done-for-you Reddit marketing agency, if you'd rather hand the work off.
• BacklinkBot: backlinks and AI-search visibility for SaaS founders.
