Compound a list of period returns into a total growth factor. Call when multi-period performance rollups from return series you already have. Returns compounded factor and total return as deterministic JSON for $0.001 US...
Zip key and value lists into an object. Call when you rebuild maps from parallel agent arrays. Returns object and count for $0.001 USDC via x402 on Base. No network, no keys, no retention; first-party local JSON only. Re...
Look up the current Total Value Locked (TVL) for a DeFi protocol from an open DeFi analytics API. Identify the protocol by its slug (uniswap, aave, lido, ethena, etc.). Returns the total TVL plus per-chain breakdown and...
Count characters, words, lines, and (optionally) occurrences of a substring in text.
Validate an ISBN-10 or ISBN-13 checksum (hyphens/spaces ignored) and report which format it is.
Encode text to Morse code or decode it back. mode: encode (default) or decode. Words separated by ' / '.
Percentage helper. op: "of" (a% of b), "change" (% change a→b), "ratio" (a is what % of b).
Convert an integer (1-3999) to Roman numerals, or a Roman numeral back to an integer. Auto-detects direction.
Line-by-line diff of two texts (LCS). Returns unified-style ops and change counts. Up to 2000 lines per side.
Decompress a base64-encoded Brotli payload. Returns the result as utf8 (text) or base64 (binary). Refuses to expand past 10MB to defend against zip bombs.
Reverse a text string to build a replayable transformation fixture. Call when you need this bounded result before handing data to a downstream tool. Returns deterministic machine-readable JSON for $0.001 USDC via x402 on...
Extract file extension from a path or URL path segment. Call when you need this bounded result before handing data to a downstream tool. Returns deterministic machine-readable JSON for $0.001 USDC via x402 on Base. Hones...
Extract webpage metadata, OpenGraph and JSON-LD for one public URL. Scalar single-URL contract for MCP and autonomous buyer runtimes.
Compute a precise age (years, months, days) from a birth date to today (or a given date), plus total days.
Look up the Autonomous System (ASN), prefix, country, registry, and allocation date for an IPv4 address - or for a hostname (which is resolved first). Uses a free public DNS-based IP→ASN mapping service; no HTTPS upstrea...
Base32 (RFC 4648) encode or decode text. mode: encode (default) or decode.
Base64 encode or decode text. mode: encode (default) or decode. Handles URL-safe base64 on decode.
Count business days (Mon–Fri) between two dates, inclusive of the start, exclusive of the end. Optional list of holiday dates to skip.
Safely evaluate an arithmetic expression (+ - * / % ^ and parentheses). No code execution - a real parser, not eval.
CRC-32 checksum of a text string (hex), the IEEE polynomial used by zip/png/gzip.
Parse a 5-field cron expression and return the next N run times (UTC).
Validate CSV structure: consistent column counts across rows, properly closed quotes, delimiter detection. Returns row/column counts and any structural errors. Pure CPU.
Difference between two dates/times in ms, seconds, minutes, hours, days, and a human summary.
