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#
Sign in at arkolith.com/connect (Google or email magic link) and a key is minted for you. No card needed: your wallet starts with a one-time grant of 500 evaluation credits, enough to verify the data before you pay. The connect page shows your key once and gives you a ready-to-paste MCP command.
2 · Connect the MCP server#
Add Arkolith to Claude Code (or any MCP client) with one command:
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:
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:
{
"jsonrpc": "2.0",
"id": 1,
"method": "tools/call",
"params": {
"name": "capital_change_brief",
"arguments": {
"ticker": "MREO"
}
}
}Where to go next#
- · Understand the capital-change workflow: outcomes, coverage, evidence, and caveats.
- · Browse the tool reference: every dataset, with runnable examples.
- · Cross-source signals: where insiders, funds, and Congress agree (the moat join).
- · Credits & pricing: what each call costs and how the evaluation grant works.
- · Authentication: keys, rate limits, and error handling.
