## Tools (15)

- `get_bars`: Resampled intraday bars at custom timeframes (3, 6, 9, 12, 15, 30, 60, 240 min) for one ticker. Every bar carries absolute open/high/low/close plus fractional change from the daily open, whatever the interval, and volume and transactions. $0.015 USDC per day.
- `get_brief`: Full research brief: price, fundamentals, insiders, splits for one ticker. $0.25 USDC.
- `get_company`: Company profile: name, CIK, industry, exchange, fiscal year. $0.005 USDC.
- `get_filings`: SEC filing index (10-K, 10-Q, 8-K, proxies) for a ticker. $0.01 USDC; add sections=[risk_factors, mdna] to extract full section text from the latest 10-K/10-Q for $0.05.
- `get_fundamentals`: Quarterly fundamentals from SEC EDGAR (revenue, EPS, margins, etc). $0.02 USDC.
- `get_insiders`: Insider transactions (Form 4) from SEC EDGAR. $0.02 USDC.
- `get_pricing`: Pricing and data coverage information. Free.
- `get_sample`: FREE, no payment: real intraday OHLCV bars for AAPL on 2024-01-02, identical in shape to a paid query. Call this first to verify data quality before spending. Takes no arguments — fixed ticker and date.
- `get_stats`: Platform statistics. Free.
- `list_tickers`: List all tickers that traded on a given date. $0.005 USDC.
- `query_batch`: Multiple tickers for one date. Every bar carries absolute open/high/low/close plus fractional change from that ticker's own daily open. $0.02/ticker, no limit.
- `query_daily`: Daily OHLCV bars plus VWAP, range_pct and true_range_pct for one ticker over a date range. range_pct = (high - low) / open is a ready-made volatility read; true_range_pct also captures the overnight gap. Day-level aggregates — the cheapest way to cover long histories. $0.001/year.
- `query_minute_bars`: Full trading day of intraday bars for one US stock (interval 3-240 min, default 3m). Every bar carries absolute open/high/low/close plus pct_open/pct_high/pct_low/pct_close (fractional change from that day's open), volume and transactions. $0.025 USDC.
- `query_range`: Multi-day intraday bars for one ticker (interval 3-240 min, default 3m). Every bar carries absolute open/high/low/close plus fractional change from that day's own open — percentages reset daily, not cumulative. $0.01/day, no day limit.
- `scan_market`: Scan all US stocks on a date for custom criteria (gaps, volume, change). Returns pct_change, range_pct, pct_gap, true_range_pct, volume and volume_ratio per match — criteria in percent (5 = 5%), outputs fractional (0.05 = 5%). $0.10 USDC.
