CallSlot

Find published work phones, emails, LinkedIn, and other first-party routes. Type a person, a company, or paste a list, then click Find. Think shows every search and page read. The table adds LinkedIn and other public links when a page or listing printed them. Empty cells mean not published. No personal cells and no data brokers.


Ready

Large company batches

Paste up to 500 companies above, then start a background batch. Each company is a separate paid use when billing is enabled. Results appear here as they finish; you can close the page and return later.

10,000 people/day capacity and price

Estimate company searches from the people each company lookup actually returns. A named-person search usually reads many more pages per person.

Assisted pages use TinyFish Fetch. The hybrid path reads public pages directly first, then uses TinyFish only where needed. Measured samples: 0, 4, and 40 assisted pages/company; results vary sharply by site. Firecrawl is an unconnected alternative using its published Growth monthly plan: $399 for 500,000 credits, then $5 per 2,500 extra credits.

Connect Claude Code

Same tools as Find: lookup_person and lookup_people. Use header x-api-key with the raw access key (no Bearer).

MCP URL https://www.callslot.space/mcp

Header name x-api-key · value YOUR_ACCESS_KEY

  1. Copy your access key from the Access key field above (or ask the CallSlot owner for one).
  2. Add the server in a terminal (any repo): 
    claude mcp add --transport http callslot https://www.callslot.space/mcp --header "x-api-key: YOUR_ACCESS_KEY"
  3. Open Claude Code (claude) in that project.
  4. Type /mcp in Claude Code. CallSlot should show as connected, with lookup_person and lookup_people.
  5. Ask it to look someone up, for example: look up the published CEO at OceanFirst Bank.

Project file .mcp.json (same header):

{
  "mcpServers": {
    "callslot": {
      "type": "http",
      "url": "https://www.callslot.space/mcp",
      "headers": { "x-api-key": "YOUR_ACCESS_KEY" }
    }
  }
}

Your timezone comes from this browser. Theirs comes from a published address, not the server clock.

Their time is 9am–5pm where they work. Your time is the same instant on this computer. Source is the page that published the address. recommended = strong evidence · consider = weak overlap hint · not available = do not dial

  1. No call-timing evidence is being used.

CallSlot does not buy data-broker dumps, infer presence, or autodial. Uncertain timezone, opt-out, or a missing business channel stops a live-call recommendation.
