Quickstart

From zero to one evidence-backed answer in a few minutes, over MCP for agents or plain HTTP for everything else.

1 · Get an API key#

Create your account at arkolith.com/auth/signup (Google or email magic link). The $1 trial starts at signup: three days of Starter research access with 300 trial credits, then $29/mo unless you cancel before day 3. A key is minted for you, shown once, with a ready-to-paste MCP command.

Keep your key secret
A key carries your credits. Pass it as a header, never in a URL or committed file. Rotate it any time from your account.

2 · Connect the MCP server#

Add Arkolith to Claude Code (or any MCP client) with one command:

bash
claude mcp add --transport http arkolith https://arkolith.com/api/mcp \
  --header "Authorization: Bearer YOUR_API_KEY"

Restart the client and your agent can now discover every tool. tools/list is free. Ask “what changed in MREO's reported institutional ownership, did insiders corroborate it, and what SEC filings prove it?” and it can call capital_change_brief for you.

3 · Make your first call#

The same current capital-change question for MREO over MCP (JSON-RPC) and REST:

bash
curl -X POST https://arkolith.com/api/mcp \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "capital_change_brief",
    "arguments": {
      "ticker": "MREO"
    }
  }
}'

The raw MCP tools/call body, if you're wiring a client by hand:

json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "capital_change_brief",
    "arguments": {
      "ticker": "MREO"
    }
  }
}
