Structured JSON Repair

Repair messy or invalid JSON (the kind LLMs and tools often emit) into clean, valid JSON, and optionally validate/coerce it against a JSON Schema. Pure deterministic compute — no network or model calls. What it fixes: trailing commas, single-quoted strings, unquoted keys, Python literals (None/True/False), NaN/Infinity, Markdown code-fence wrappers, and truncated/garbled tails. When to use: you received text that should be JSON but JSON.parse fails, or you have JSON that must conform to a spec

Tabular to JSON

Convert messy tabular text into clean, typed JSON rows. Auto-detects CSV, TSV, or a Markdown table and returns one JSON object per row plus an inferred column/type summary. Pure deterministic compute — no network or model calls. What it handles: delimiter sniffing (comma/semicolon/tab/pipe), quoted fields with embedded commas and newlines, BOM, ragged rows (padded/truncated), Markdown separator rows and escaped pipes, header auto-detection, and per-column type inference (integer/number/boolean/

US Treasury Yield Curve

Current and recent U.S. Treasury par yield curve rates, with the spreads traders actually watch already computed. Returns every published tenor (1 month through 30 years) for the latest business day, plus the 2s10s spread, the 3m10y spread, and an inversion flag. Source is the U.S. Treasury's official daily par yield curve (public domain, no attribution required). When to use: you need risk-free rates for discounting, a read on the curve's shape, or recession-signal context (curve inversion).

US CPI Inflation

Latest U.S. CPI inflation from the Bureau of Labor Statistics, with the rates already computed. BLS publishes index levels, not inflation rates. This tool does the arithmetic: headline and core (all items less food and energy) CPI, each with year-over-year and month-over-month percent change. Year-over-year uses not-seasonally-adjusted data and month-over-month uses seasonally adjusted, matching how these figures are conventionally reported. When to use: you need the current inflation rate, a

US Jobs Report

Latest U.S. labour-market data from the Bureau of Labor Statistics, with the headline changes computed. Returns the unemployment rate, labour force participation rate, total nonfarm payrolls, the month-over-month change in payrolls (the "jobs added" number that leads the Employment Situation report), average hourly earnings, and year-over-year wage growth. All series are seasonally adjusted. BLS publishes levels; the month-over-month and year-over-year changes are computed here. When to use:

US PCE Inflation (Fed's Preferred Gauge)

The Fed's preferred inflation gauge: Personal Consumption Expenditures (PCE) price index, headline and core. The Federal Reserve targets PCE inflation, not CPI, when setting policy. Returns the headline index and "PCE excluding food and energy" (the actual core measure the Fed watches), each with year-over-year and month-over-month percent change computed from BEA's published index levels. When to use: Fed-policy reasoning, comparing the Fed's actual inflation target against CPI, macro researc

US Real GDP Growth

Latest U.S. real GDP growth rate, from BEA's National Income and Product Accounts. Returns the annualized quarter-over-quarter growth rate for the most recent quarter (the headline "how is the economy growing" number), plus the prior two quarters for trend context. BEA publishes this table as a percent-change series already, so no growth-rate math is needed here. When to use: reading the pace of economic growth, recession-risk context (two consecutive negative quarters), or macro backdrop for

US Retail Sales

Latest U.S. retail sales, seasonally adjusted, excluding motor vehicles and parts — the "ex-autos" figure most commonly cited as a consumer-spending signal. Returns the seasonally-adjusted monthly sales total in millions of dollars, with month-over-month and year-over-year percent change computed from the Census Bureau's Advance Monthly Retail Trade Survey. When to use: gauging consumer spending strength, a component of GDP nowcasting, retail-sector demand signal. When NOT to use: you need ca

US Housing Starts & Permits

Latest U.S. new residential construction: housing starts and building permits, seasonally-adjusted annualized rate. Housing starts (ground broken) and permits (approved but not necessarily started, a leading indicator) are the two headline figures from the Census Bureau's New Residential Construction survey, reported at a seasonally-adjusted annualized rate in thousands of units. When to use: gauging housing-market momentum, a leading indicator for construction activity (permits lead starts),

US Energy Markets (Crude & Natural Gas)

Latest U.S. energy market data from the Energy Information Administration: WTI crude price, crude oil inventories, and natural gas storage. Combines three EIA series that usually require separate lookups: the WTI Cushing spot price, weekly U.S. crude oil ending stocks (with week-over-week percent change), and weekly natural gas underground storage (with week-over-week percent change). When to use: energy-sector context, inflation pass-through analysis (energy prices feed CPI/PCE), trading arou

US Economic Release Calendar

Upcoming U.S. economic data releases, with dates and times, from the official BLS news-release schedule. Answers "what macro data drops next, and when" without scraping a web page. Covers the BLS release set that moves markets: CPI, PPI, the Employment Situation (nonfarm payrolls and unemployment), JOLTS, Employment Cost Index, real earnings and productivity. When to use: planning around data risk, checking whether a print lands before a decision, or building a watchlist of upcoming events. W

SEC Insider Transactions (Form 4)

Insider buying and selling for a U.S. public company, parsed from SEC Form 4 filings. Form 4 is published as raw ownership XML, one document per filing, with the machine-readable file hidden behind an XSL-rendered URL. This resolves the ticker to a CIK, finds the most recent filings, fetches each XML document, and returns clean transactions: who traded, their role, the date, the SEC transaction code with its plain-English meaning, share count, price, computed dollar value, and shares held after

SEC Company Financials (XBRL)

Key financials for a U.S. public company, pulled from SEC XBRL company facts. Returns revenue, net income, diluted EPS, total assets, total liabilities, shareholders' equity and cash, each with the most recent ANNUAL and QUARTERLY figure, the period covered, and the form it came from. Handles two things that trip up naive XBRL queries: filers migrated from the "Revenues" tag to "RevenueFromContractWithCustomerExcludingAssessedTax" under ASC 606, so each concept tries several tags in order; and

SEC 13F Institutional Holdings

Institutional stock holdings for a fund manager, from its latest SEC Form 13F. 13F filings split the actual holdings into a separate "information table" XML document that the filing index does not point at directly; this locates it, parses every position, and rolls up lots reported separately (different share classes, put/call splits) into one row per issuer. When to use: seeing what a fund or institution holds and how much, tracking "smart money" positioning, portfolio research. When NOT to

SEC Filings Feed

Recent SEC filings for a company, newest first, with 8-K item codes translated to plain English. A general-purpose filings feed: any form type, or a specific set (8-K for material events, 10-K/10-Q for periodic reports, S-1 for new-issue prospectuses, SC 13D/13G for activist and passive stakes). 8-K filings include their item numbers (e.g. "5.02") decoded into a label ("Departure/appointment of directors or officers") rather than leaving you to look up the code. When to use: monitoring a compa

SEC Full-Text Filing Search

Full-text search across all SEC EDGAR filings since 2001 for a keyword or phrase. Wraps EDGAR's own full-text search index, so it covers every filer and form type, not just a single company. Useful for finding who is disclosing a particular risk, technology, litigation, or event across the entire market. When to use: cross-company research ("who is disclosing AI-related risk factors"), finding filings that mention a specific term, litigation or regulatory tracking. When NOT to use: you alread

On-chain Token Balances (bulk)

Read an ERC-20 token balance for up to 500 wallet addresses in a SINGLE call. Doing this yourself means issuing hundreds of eth_call requests, batching them, handling per-provider rate limits and partial failures, then scaling raw integers by token decimals. This does all of that and returns clean, ready-to-use numbers plus the block height the snapshot was taken at. Supported chains: base (default), ethereum, optimism, arbitrum, polygon. Defaults to canonical USDC on the selected chain when n

On-chain Portfolio (USD-valued)

USD-valued portfolio for a wallet on Base, priced from Chainlink on-chain oracles. Reads the wallet's native ETH plus major ERC-20 balances, reads each asset's Chainlink USD aggregator directly on-chain, and returns holdings with per-asset prices and dollar values, sorted largest first, stamped with the block height. Prices come from Chainlink contracts rather than a price API, so there is no vendor key, no rate limit, and no third-party terms attached to the result. Covered assets: ETH (nati

Cross-chain Token Balance

The same token's balance for one address across multiple EVM chains, in a single call. USDC (and similar assets) has a DIFFERENT contract address on every chain; checking a wallet's total position means resolving each chain's canonical address and querying it separately. This does that and sums the total, so a multi-chain treasury view does not require N separate calls. Supported chains: base, ethereum, optimism, arbitrum, polygon. Supported tokens: USDC (more may be added over time). When to

Chainlink Oracle Price

Read any Chainlink price feed directly on-chain — a named pair or a raw feed address. Calls latestRoundData on the feed contract itself, so there is no price-API vendor, no rate limit, and no key. Includes the feed's last-updated timestamp and its age in seconds, so you can judge staleness yourself rather than trusting an unlabeled number. Known named pairs on Base: ETH/USD, BTC/USD, USDC/USD. Any other feed address on any supported chain also works. When to use: getting a specific asset's pr

Multi-chain Gas Price

Current gas price across multiple EVM chains in a single call. Reads eth_gasPrice on every requested chain in parallel and returns gwei, so you do not have to query each chain's RPC separately and convert units yourself. Supported chains: base, ethereum, optimism, arbitrum, polygon. When to use: choosing the cheapest chain to transact on right now, cost estimation before submitting a transaction, monitoring for a low-gas window. When NOT to use: you need an EIP-1559 fee breakdown (base fee v
