Parse a datetime from any format (ISO 8601, Unix timestamp in seconds or milliseconds, RFC 2822, or natural date string) and return it in every common format: ISO 8601, Unix (seconds), Unix (ms), RFC 2822, date-only, time-only, day of week, and human-relative (e.g. '3 days ago').

Convert between Unix epoch timestamps and ISO 8601 date strings in both directions. Provide either an epoch (seconds or milliseconds) or an ISO date string. Returns both representations plus UTC and date components.

Encode text to Morse code or decode it back. mode: encode (default) or decode. Words separated by ' / '.

Compress a string with gzip (RFC 1952) and return it as base64. Reports input bytes, output bytes, and the compression ratio so you can decide if it was worth doing. Input can be plain text (utf8) or already-binary content (base64 or hex).

Validate an ISBN-10 or ISBN-13 checksum (hyphens/spaces ignored) and report which format it is.

Decompress a base64-encoded gzip payload. Returns the result as utf8 (text) or base64 (binary). Refuses to expand past 10MB to defend against zip bombs.

OHLCV candles for one perpetual at any interval from 1 minute to 1 month, up to the venue's history, with a window summary of open, close, change, high, low and volume. Use it when an agent needs price history for a chart, a backtest or an indicator without an exchange account or API key.

Parse iCalendar (.ics) text into structured JSON events: summary, start/end, location, organizer, attendees, status, and RRULE. Optional bounded recurrence expansion (expand:true, capped occurrences). Deterministic, pure CPU - send the ICS text, not a URL.

Convert an integer (1-3999) to Roman numerals, or a Roman numeral back to an integer. Auto-detects direction.

Search autocomplete: query suggestions for a partial input as a flat JSON array. Useful for query expansion, did-you-mean refinement, and topic exploration. Returns up to 20 suggestions.

USD price for up to 50 Solana token mints in one call from a Solana DEX aggregator's price API: price, 24h change, liquidity, decimals and the block the price was read at. Mints the aggregator does not price come back listed under missing rather than erroring the batch. Pass mint addresses, not tickers (resolve tickers with sol-token-search or sol-token-lookup). Keyless. Powered by Jupiter.

Current time: UTC ISO, epoch seconds/ms, day of week/year, ISO week - optionally rendered in any IANA timezone.

Percent-encode or decode a string for URLs. mode: encode (default) or decode. component: true (default) uses encodeURIComponent semantics.

Line-by-line diff of two texts (LCS). Returns unified-style ops and change counts. Up to 2000 lines per side.

Generate ULIDs (sortable, timestamp-prefixed identifiers).

Official European Central Bank euro reference exchange rates (about 30 currencies) and currency conversion between any two of them, with reference date.

Verify whether a specific npm or PyPI package version exists before installation, resolve the current/latest version, and report deprecation or yank state when available, plus license and runtime requirement. This is a public-registry package install preflight; it does not resolve dependency graphs or perform vulnerability analysis. Base mainnet USDC

Snapshot of every series, all countries

Company/person/organization facts from Wikidata. Pass an entity id (e.g. Q312 for Apple Inc.) for the enrichment record - label, description, aliases, and a curated fact set (inception, HQ location, country, industry, founders, CEO, employees, revenue, official website, LEI, ticker + exchange, ISIN, logo; for people: birth/death dates, citizenship, occupation) with item references resolved to human-readable labels.

Resolve a bare public domain into operational registration, DNS, HTTPS/TLS and mail-policy state using IANA-routed RDAP, DNS, MX/TXT/SPF/DMARC and a bounded TLS probe. No registrant personal data, vulnerability scanning, mailbox existence or deliverability claim. Provider uncertainty is explicit. Base mainnet USDC
