How Stocklake is built — the data pipeline, the tools, and what the numbers actually say.
Install the n8n-nodes-stocklake community node on self-hosted n8n — typed operations, a credential test button, and three ready-to-paste example workflows.
Every stock and every signal used to carry a handful of separate 0-10 numbers set by different AI calls. We replaced all of it with two comparable 0-100 numbers: AI Score and Signal Score. Here's what changed and why.
Every Stocklake signal used to carry three AI-set numbers that meant something different depending on which screener wrote them. Here's how signal_score replaced them with one comparable 0–100 score — and where it shows up across the public API today.
Three Stocklake screeners suppress entire categories of ideas before AI ever scores them — not on a hunch, but because the evidence said so. One of those gates has since been replaced entirely.
Picking an MCP server for stock market data? The real dividing line isn't price or coverage — it's whether the server hands you raw numbers or a verdict your agent can act on.
A real example: an Apple executive sold $885K in stock while institutions bought 331 million net shares the same quarter. Here's why an insider trading API needs to reconcile both, not just list one.
No account, no key, no card. Just an IP address and a daily counter. Here's exactly what Stocklake's guest tier returns, and the point at which it's actually worth signing up.
You're on the free tier and it's working fine — so what's actually behind the wall? A walkthrough of the 10 Pro-only tools, the hidden Pro fields already inside your free tools, and what the pro_required error actually shows you.
get_signals merges technical exhaustion, news, and sentiment sources into one deduped, scored, sourced feed an agent can actually act on — no babysitting eleven separate screener feeds yourself.
Ten years ago it was a spreadsheet tracking one portfolio. Then a pandemic rebuild, an almost-shipped app that never saw the light of day, and a pivot to AI that became Stocklake.
Why every Stocklake tool starts with market and sector context before touching a single stock — and the production incident that shaped why most tools default to recent data, not everything.
