Why this exists

The official X API starts at a monthly subscription and a developer-account approval. If an agent just needs to know what people are saying right now, that's a lot of setup for a handful of queries. This server charges per request instead — a hundred searches costs about sixty cents, and there is nothing to cancel.

Tools

x_search — $0.02

Full advanced-search syntax. Returns up to 20 newest matches with author handle, follower count, text, timestamp, permalink, likes, retweets, replies, and views. Need more than 20? A full answer ends with next.older — pass its cursor value back (same query) for the next 20 older matches, $0.02 a page. No slicing dates by hand.

x_digest — $0.05

Everything above plus an AI-written digest generated only from the returned tweets:

{
  "summary": "3-5 sentences on what's actually being said",
  "sentiment": "positive | negative | mixed | neutral",
  "sentiment_note": "why it leans that way",
  "key_themes": ["..."],
  "driving_accounts": ["@handle", "..."],
  "notable_post_urls": ["https://x.com/..."]
}

Use x_digest when you want the takeaway; x_search when you want the raw posts.

x_leads — $0.05

Same advanced-search syntax as x_search, but returns the PEOPLE behind the matching posts instead of the posts themselves — enriched with bio, website, emails found in the bio, follower count, location, a DM-open flag, and every matching post per person:

{
  "result_count": 20,
  "lead_count": 8,
  "leads": [{ "username": "someone", "followers": 5000, "emails": [], "matched_posts": [] }]
}

Inputs: query (required, same syntax as x_search), max (optional, "20" or "40" — default 20). Use for recruiting, cofounder search, B2B lead generation, influencer discovery, community sourcing.

x_pain_points — $0.05

Pass a product or brand name/handle, get clustered complaints, feature requests, and praise mined from live X posts, with verbatim quotes and URLs:

{
  "product": "Cursor",
  "analysis": { "summary": "...", "pain_points": [{ "theme": "...", "count": 4, "severity": "medium" }] }
}

Input: product (required — a name or an X handle). Use for product research, competitor research, churn signals, roadmap input.

x_user_timeline — $0.02

An account's own recent posts (originals, replies, retweets), newest first. Input: username (required). Use: x_user_timeline username="elonmusk" to track a competitor's or founder's own feed.

x_profile — $0.02

One account's bio, website, location, join date, follower/following counts, and verified status. Input: username (required). Use: x_profile username="cursor_ai" to qualify a lead before you reach out.

x_tweet — $0.01

One tweet by numeric ID: full text, author, timestamp, permalink, engagement. Input: id (required). Use: x_tweet id="1859012345678901234" to re-check a specific post you already found.

x_replies — $0.02

The reply thread under one tweet, newest first. Input: id (required, same as x_tweet). Use: x_replies id="1859012345678901234" to see how people reacted to a specific post.

x_find_accounts — $0.02

Search for ACCOUNTS matching a name, keyword, or topic — not posts. Input: query (required, same syntax as x_search). Use: x_find_accounts query="solar installer hawaii" to build a shortlist of accounts to follow up on.

x_account_verdict — $0.02

A short AI-written read on one account: what it's about, how active/engaged it is, and whether it's worth following up with. Input: username (required). Use: x_account_verdict username="someone" to triage a lead fast without reading the profile yourself.

x_watch — $0.05

Same search as x_search, but only returns posts newer than a cursor you supply. Inputs: query (required), since (optional — an ISO timestamp or the cursor.newest_id from your last x_watch call). Use: poll a brand/ticker/hashtag on a schedule without re-paying for posts you've already seen. A check that finds nothing new is not charged — you only pay when there is news.

x_ticker_pulse — $0.02

Facts about one US stock ticker's X/Twitter activity, built for trading agents: post volume vs the prior window, top posts by likes, most active accounts, and keyword topic flags (earnings, guidance, lawsuit, SEC investigation, recall, M&A, layoffs, upgrade/downgrade, short report, dividend, buyback, CEO). Inputs: ticker (required, 1-6 letters, with or without a leading $), window (optional, 24h default or 7d). Use: x_ticker_pulse ticker="TSLA" window="24h". FACTS ONLY — counts and keyword matches, never a sentiment verdict, price target, or buy/sell/hold signal.

x_list — $0.05

A watchlist of 2-50 handles' combined recent posts in ONE call, newest first, deduped, with a per-handle post count and a since-cursor for only-what's-new next time — instead of splitting a watchlist into several from:a OR from:b x_search calls (X caps how many OR terms one search can carry):

{
  "handle_count": 3, "result_count": 40, "truncated": true,
  "per_handle_counts": { "elonmusk": 20, "naval": 12, "balajis": 8 },
  "cursor": { "newest_id": "1967000000000000001" },
  "tweets": [{ "author": "elonmusk", "text": "...", "likes": 1234 }]
}

Inputs: handles (required — comma or space separated, @ optional, 2-50 handles), since (optional — ISO timestamp or a tweet ID from cursor.newest_id), limit (optional, 1-100, default 40). Use: x_list handles="elonmusk,naval,balajis" to check a watchlist in one call.

x_followers — $0.02

One page (up to 20 shown) of an account's followers: handle, name, bio, follower/following counts, verified status, DM-open flag. Inputs: username (required), cursor (optional, from a prior call's next.older). Use: x_followers username="elonmusk" for audience research or lead sourcing.

x_following — $0.02

One page (up to 20 shown) of who an account follows — same shape as x_followers. Inputs: username (required), cursor (optional). Use: x_following username="elonmusk" to map an account's network.

x_mentions — $0.02

One page (up to 20 shown) of posts mentioning a handle: author, follower count, text, timestamp, permalink, engagement. Inputs: username (required), cursor (optional). Use: x_mentions username="cursor_ai" for brand monitoring or reputation tracking.

x_engagers — $0.05

Who quoted and who retweeted one post (up to 20 each): handle, name, bio, follower count, verified status:

{ "id": "1878000000000000000", "quote_count": 5, "retweeter_count": 40, "quotes": [], "retweeters": [] }

Input: id (required, same as x_tweet). Use: x_engagers id="1878000000000000000" to find amplifiers or source leads from a viral post's audience.

x_person — $0.15

Send a handle, get an enriched person card: name, role, company, what they work on, topics, seniority guess, and contact routes (emails found on their own site or bio, LinkedIn, GitHub, DM-open flag), plus facts (followers, account age, posts/week, website). An email is only reported if it was actually found, never guessed. Input: username (required). Use: x_person username="naval". Needs X402_MAX_PRICE of at least 0.15 (see Setup).

x_leads_deep — $0.20

The whole search → profile → contact chain in one call. Searches up to 4 pages, groups the posts by author, enriches the top 10-15 people with their own website (emails, LinkedIn, GitHub), and clusters them with a one-line why-they-match each:

{
  "pages_fetched": 4, "lead_count": 10, "enriched_count": 7,
  "clusters": [{ "theme": "Solidity engineers", "lead_usernames": ["someone"] }],
  "leads": [{ "username": "someone", "emails": [], "web": { "emails": [], "links": {}, "title": "..." }, "card": { "why_they_match": "..." } }]
}

Inputs: query (required, same syntax as x_search), max (optional, "1" to "15", default "10"). Nothing found = nothing charged. Needs X402_MAX_PRICE of at least 0.20 (see Setup). Cheaper first look: x_leads.

Query syntax (x_search, x_digest, x_leads, x_find_accounts, x_watch)

Both tools take one query string:

Quick start (copy-paste)

Four ready-made files in examples/:

• examples/claude-desktop.json — Claude Desktop config block

• examples/claude-code.md — claude mcp add one-liner + Cursor mcp.json

• examples/x402-fetch.mjs — plain Node script, no MCP, pays from a private-key wallet

• examples/credits-curl.sh — no wallet: prepaid credits bought by card + a Bearer key

Setup

You need a Coinbase CDP wallet funded with a little USDC on Base — that wallet pays per call. Create one at portal.cdp.coinbase.com (API key + wallet secret).

Claude Desktop — add to claude_desktop_config.json:

{
  "mcpServers": {
    "twitter-signal": {
      "command": "npx",
      "args": ["-y", "twitter-signal-mcp"],
      "env": {
        "CDP_API_KEY_ID": "your-key-id",
        "CDP_API_KEY_SECRET": "your-key-secret",
        "CDP_WALLET_SECRET": "your-wallet-secret",
        "X402_MAX_PRICE": "0.05"
      }
    }
  }
}

X402_MAX_PRICE is a hard per-call ceiling in USD. If the endpoint ever quotes more than this, the request is refused before anything is signed — no charge. The default 0.05 covers every tool except the two premium ones: x_person ($0.15) and x_leads_deep ($0.20). Set X402_MAX_PRICE to 0.25 to unlock them (the default stays 0.05 on purpose, so an agent can't spend more than you expect).

Cost & safety

• You are only ever charged for a successful response. Invalid queries are rejected before payment (HTTP 400, no settlement).

• Nothing found = nothing charged. An empty x_search / x_digest / x_leads / x_pain_points / x_watch comes back as no_results with charged: false — the payment is never settled.

• Same call within 10 minutes = free. Repeat the exact call from the same wallet and you get the saved answer (meta.charged: false) at no cost.

• If the upstream tweet source fails after payment, the API returns an explicit error and logs the call for refund rather than pretending it worked.

• Gas is covered by the facilitator — you spend USDC only.

• Identical queries within 60 seconds are served from cache.

How it works

MCP client → twitter-signal-mcp → 402 challenge → sign USDC authorization
           → facilitator settles on Base → data returned

Protocol: x402 v2 (CAIP-2 networks, PAYMENT-REQUIRED challenge header). A v1 client cannot talk to this API.
