Stocklake Pro Tier: What 10 Extra Tools Unlock

If you're registered to the free tier, you're probably not thinking about upgrading. The 8 free tools cover price, fundamentals, technical indicators, history, headlines, a screener, market movers, and an earnings calendar — a complete toolkit for "what's the price, what's the trend, what's coming up." Most simple agent builds never hit the 200-calls-a-day ceiling, let alone need anything else. So this isn't a fear-of-missing-out pitch. It's a straight answer to a question free users actually ask: what does Pro do that free doesn't, in terms an agent would notice?

The part that's easy to miss: two tools you already call

get_stock and get_stocks aren't different tools on Pro — same call, same params. But the response carries two extra blocks that only populate for Pro callers: a rating (a 0–10 composite score plus direction, blended from six indicator groups — RSI, MACD, Bollinger Bands, the SMA trend stack, Williams %R, and the Ultimate Oscillator — with transparent per-group weighting, not a black box) and a signals object (the full precomputed indicator stack individually labeled — those six plus VIX Fix, Williams A/D, DeMark TD Sequential, and Elliott Wave — instead of raw numbers you'd have to interpret yourself).

Concretely: on free, you get RSI 22.4 and have to know that's oversold. On Pro, the same call returns a rating of 9.0 with signals showing RSI, Williams %R, Bollinger position, and the Ultimate Oscillator all independently flagging oversold at once — the agreement between four indicators is exactly what pushed the score that high, and you don't have to write the logic that checks for it.

The 10 tools that don't exist on free at all

These aren't gated fields on a shared tool — calling them on a free key returns an error, not a partial response. Grouped by what they actually add:

One-call research. get_stock_research folds a stock's price, fundamentals, recent news, insider activity, and an AI-written summary (verdict, confidence, key points, risks) into a single response. The free-tier path to the same picture is 4–5 separate calls stitched together yourself; this is the version where the stitching already happened.

The live signal feed. get_signals is the curated cross-source queue described in Calling It Signals — active, scored, sourced setups, not a raw dump you'd have to filter.

Ownership and conviction context. get_insider_activity — insider buy/sell counts plus institutional ownership, with the insider and institutional sides each scored and reconciled into one overall signal, not just a transaction list. The companion post walks through a real case where the two sides disagree.

Market and sector regime. get_market_assessment (macro regime + market outlook merged — risk appetite, key risks, preferred/avoided sectors) and get_sector_intelligence (per-sector signal, rotation read, cycle stage). Free's get_market_pulse gives you VIX and breadth; these two answer "so what does that mean for where money's rotating."

History with depth. get_indicator_history — up to 730 days of daily indicator snapshots. Free's get_stock_history gives you OHLCV bars; this gives you the indicator's own trajectory over time, not just today's reading. It's also the one Pro tool with a real payload knob worth knowing about: it defaults to a slim 6-field snapshot (price, RSI, MACD histogram, Bollinger %B, SMA20/SMA200) and only returns the specialized fields — Williams %R, Ultimate Oscillator, VIX Fix, Williams A/D, DeMark, analyst rating and target — when you pass full: true.

Macro calendar, at the economy level. get_economic_calendar — recently released and upcoming interest rate decisions, CPI, GDP, and non-farm payrolls prints, with actual-vs-previous values, a key_events_only filter for just the market-moving releases, and a major_only filter to skip the smaller economies. No AI, no synthesis — the same "what's coming up" precomputation as the free earnings calendar, just scoped to the whole economy instead of one company.

Curated news, not a headline list. get_news_feed — market-wide news pre-scored for relevance, versus free get_stock_news's plain headlines with no AI fields.

Forward-looking earnings read. get_earnings_intelligence — an AI verdict and risk callouts per stock in the earnings window, not just the date and estimate.

Your own list, tracked server-side. get_watchlist — account-scoped, resolves from your key automatically, no client-side state to maintain.

What actually happens when a free key hits a Pro tool

Not a bare 403. The error itself is built to be useful even if you don't upgrade on the spot:

{
  "error": "pro_required",
  "message": "This tool needs Pro tier...",
  "preview": {
    "symbol": "NUVL", "direction": "LONG",
    "signal_score_band": "Very Strong"
  },
  "upgrade": "https://stocklake.dev/pricing?ref=mcp"
}

The preview is real (truncated) data — one live example, not a mocked screenshot. The raw 0-100 signal_score itself stays Pro-only; the band is the free-safe version, same boundary every other locked preview in the API draws. If you're an agent relaying this to whoever's using you, you can say "there's a Very Strong live signal on NUVL, but reading the full feed — the actual score, source, and rationale — needs Pro" instead of just failing silently or making something up.

Where this actually changes a decision

A realistic chain: free's get_screener narrows a sector down to a shortlist — that part costs nothing extra. Then, for the 2–3 names that made the cut, Pro's get_stock rating tells you which ones have technical agreement worth a closer look (a 9.0 vs a 6.0 is a real filter, not noise), and get_stock_research gives you the one-call deep dive on whichever passed that bar. You're not paying for Pro on every call — you're paying for it on the handful of names that made it past a free filter first. That's the actual shape of how it gets used, not "everything now costs more."

If the 8 free tools already answer what you need, there's no reason to change anything. If you've found yourself making 4 calls to answer one question, or wishing a rating number existed instead of raw indicator values you have to interpret — that's the actual signal (no pun intended) that Pro would save you real work, not just add a checkbox.
