Use Twelve Data well with AI

Checks your Twelve Data account, plan and remaining credits, resolves the exact symbol and exchange, then picks the cheapest tool that answers your question. It is read-only and asks before any change to account state.

Use it when

You want the latest price or quote for a stock, forex pair, crypto pair or ETF
A Twelve Data call returned nothing or an error and you need to know why
You are about to pull a large history and want to check your credit budget first

Tools it uses

auth_status
get_api_usage
get_reference_data
get_price
get_quote
get_time_series
currency_conversion
get_market_movers
get_market_state
get_technical_indicator
get_earliest_timestamp

Example

What is the latest price of Vodafone on the London exchange, and how many API credits do I have left?

Your plan is active with 4,200 credits remaining for this window. VOD resolves to Vodafone Group on the London Stock Exchange, quoted in GBp. The latest price is 72.40 GBp as of the last trade; the exchange is currently closed, so this is the closing price, not a live quote.

Check analyst consensus and holdings for a stock with AI

Reads analyst estimate trends, ratings, price targets, insider trades, institutional holders and recent SEC filings for one stock, and says how much weight each signal deserves. It is read-only and does not give buy or sell advice.

Use it when

You want to know whether estimates for a stock are being revised up or down.
You are checking whether insiders have been buying or selling and whether it looks routine.
You want to see who the largest institutional holders are and whether they recently added or cut their positions.

Tools it uses

get_reference_data
get_earnings
get_analyst_data

Example

What are analysts saying about this stock, and have insiders been buying or selling recently?

Estimates for the next year are being revised up over the last three months. Of 14 ratings, 9 are buy, 4 hold and 1 sell, and 11 of them are recent. The mean price target is 212 against a price of 186, from 11 recent targets. Two insiders bought shares last quarter and the sales were small and routine. The reported holder data is one quarter behind, so treat it as a snapshot.

Review a listed company's fundamentals with Twelve Data

Builds a fundamentals picture of one listed company from its income statement, balance sheet, cash flow, dividends, splits and earnings, checking that periods and currencies line up before drawing conclusions. Read-only; it changes nothing.

Use it when

You want to know whether a company's profits turn into cash
You are comparing leverage and liquidity across two periods
You need to check whether dividends are covered by free cash flow

Tools it uses

get_company_info
get_reference_data
get_financials
get_statistics
get_dividends
get_splits
get_earnings
get_ipo_calendar

Example

Give me a fundamentals review of Microsoft over the last three fiscal years, focusing on cash generation and dividends.

Reporting in USD, fiscal year ending June. Operating cash flow ran above net income in all three years, and free cash flow covered the dividend each year. Debt to equity stayed low and the current ratio held above 1.5. Two periods had one-off items in net income, so I anchored the trend on operating income. The dividend was raised each year with no split in the window.

Fund and ETF due diligence

Evaluates an ETF, mutual fund or money market fund from its holdings, risk, performance and NAV behaviour, then benchmarks it against similar funds. Read-only; it presents evidence and does not give buy or sell advice.

Use it when

You are deciding between two broad index ETFs and want to see how their holdings and risk differ.
You want to know whether a fund's recent winning streak comes from real diversification or one sector bet.
You hold a money market fund and want to check its liquidity and stability before moving cash.

Tools it uses

get_etf_data
get_mutual_fund_data
auth_status
get_api_usage
currency_conversion
get_time_series
get_price
get_earliest_timestamp
get_dividends

Example

Compare the QQQ and VOO ETFs. Which one is more concentrated, and how did each behave in the last three years?

QQQ's top ten holdings make up roughly half of the fund, against a much smaller share for VOO, so QQQ is the more concentrated bet on large technology names. Over the last three years QQQ showed higher volatility and a deeper drawdown than VOO, with a higher return; I would weigh whether that extra return is worth the added risk and the overlap with any stocks you already own. Holdings and risk figures are as of the dates the data provider returned.

Technical indicator analysis with Twelve Data

Computes and reads momentum, volatility, volume and trend indicators over a Twelve Data price series, with parameters, lookback checks and caveats. It describes conditions and does not give trade instructions.

Use it when

You want to know if a stock looks overbought, oversold or trending
You want RSI, MACD, moving averages or Bollinger bands checked together
You want to know whether a volatility squeeze or breakout is developing

Tools it uses

get_time_series
get_technical_indicator

Example

Is AAPL trending, and is RSI showing anything unusual on daily bars?

AAPL daily, 260 bars. Trend is up: price is above the 50-day and 200-day SMAs and the 50-day has risen for 6 weeks. RSI(14) is 71, its highest in three months, but it has not diverged from price. ATR(14) is near its one-year median, so volatility is normal. Read: trend and momentum agree; caveat that RSI above 70 in a trend is common and not a sell signal.

Twelve Data skills FAQ

What is a Twelve Data agent skill?

A SKILL.md file: a short playbook an AI agent loads when your request matches it. Each Twelve Data skill describes one job, which Twelve Data tools to use in which order, what to check first and when to stop and ask you.

Do the Twelve Data skills change anything on their own?

5 of the 5 only read. The others tell the agent to show you the change and wait for a yes before it creates, edits or deletes anything in Twelve Data.

Which tools can use these skills?

Any agent that reads the open Agent Skills format: Claude Code, Cursor, Codex, VS Code with Copilot and RevampKey. In RevampKey they are attached when you connect Twelve Data; elsewhere you copy the folders into your project or skills directory.

Do I need the Twelve Data MCP server too?

Yes. The skills tell the agent how to do the work; the Twelve Data MCP server gives it the tools to do it. The Twelve Data MCP setup guide covers every client.
