News headlines, latest news

8-K filings, SEC material events. Latest Form 8-K current reports for a US-listed company by ticker, name or CIK: filing date, the reported items with their meaning (results of operations, executive departures, material agreements, cybersecurity incidents, bankruptcy and others), accession number and a direct link, newest first. Public SEC EDGAR data. Use to watch a company's material events or ch

Age calculator. Exact age from a date of birth in years, months and days, total days lived, the weekday of birth, and the date of and days until the next birthday, measured today (UTC) or on any date you give. Use for age checks, forms and anniversaries.

BMI calculator. Body mass index from weight and height in metric (kg, cm) or imperial (lb, in) units, its WHO adult category (underweight, normal weight, overweight, obesity class I-III) and the weight range that counts as normal for that height. For adults; a screening number, not a diagnosis. Use for health, fitness and nutrition apps.

Loan and mortgage calculator. Monthly payment of an amortised loan or mortgage from the amount, the annual interest rate and the term, plus the total paid, the total interest and the first months of the repayment schedule (principal, interest and balance). Fixed rate, monthly payments. Use to compare loan offers or plan a mortgage.

Tip calculator. Tip and total for a bill at a tip percentage, split between any number of people, optionally rounding each share up to the next whole amount. Use for receipts, expense apps and group payments.

Decode calldata. Decode EVM transaction calldata into the function and its arguments with viem: give the function signature (transfer(address,uint256)), or leave it out to try common ERC-20, ERC-721, ERC-1155, WETH, permit and multicall functions by selector. Numbers come back as decimal strings. Use to read what a pending or past transaction does before signing; get calldata from eth_tx. A select

Great-circle distance between two latitude/longitude points (haversine on the mean earth radius) in kilometres, miles and nautical miles, plus the initial compass bearing and the midpoint. Accurate to about 0.5% against the ellipsoid. Use for delivery radius, travel and proximity checks, or sorting places by distance; for coordinates of a place name use geocode first.

JSON schema from example. Infer a JSON Schema (draft 2020-12) from an example JSON value: types, nested object properties, required keys, array item shapes merged across all items, and string formats (date-time, date, email, uri, uuid). Use to document an API response or to validate later data against the same shape.

JSON to YAML. Convert a JSON value into a YAML document (block style, no line folding), for config files, Kubernetes manifests, GitHub Actions or docs that humans edit. Up to 100 KB of JSON. Use when a tool or person wants YAML; for the reverse use yaml_to_json. Invalid JSON is a 400, uncharged.

Phone number validation. Validate and format a phone number with the libphonenumber rules: whether it is valid and possible, the E.164 form, international and national formatting, country, calling code and line type (mobile, fixed-line, toll-free, VoIP…). Give +country code, or a national number and a two-letter country. Offline: nothing is sent and it does not say the line is in service. Use to c

Caesar cipher, ROT13. Encode or decode text with a Caesar cipher: every letter A-Z shifted by 1-25 places (13, the default, is ROT13), case kept, digits and punctuation untouched. decode=true shifts back. Use for puzzles, spoiler hiding and teaching; it is not encryption.

Lorem ipsum generator. Lorem ipsum placeholder text: 1-20 paragraphs of 1-10 sentences, starting with the classic "Lorem ipsum dolor sit amet". The same seed always gives the same text. Use to fill mock-ups, templates and test data.

Morse code translator. Translate text to international Morse code (letters separated by spaces, words by /) or Morse code back to text; the direction is detected automatically or set with mode. Letters, digits and common punctuation are supported; anything else is reported, not guessed. Use for puzzles, radio practice and fun messages.

Local rules, no outside service. Use to read access logs, segment traffic or spo

YAML to JSON. Convert a YAML document (config files, Kubernetes manifests, OpenAPI specs, front matter) into JSON, parsed by the yaml library with anchors and aliases resolved (alias expansion capped against billion-laughs documents) and duplicate keys refused. Up to 100 KB. Use before feeding YAML into a JSON-only tool or schema check; for the reverse use json_to_yaml. Invalid YAML is a 400 with
