qr_code | Make a QR code for any text, URL, Solana Pay / wallet address or Wi-Fi login — as a PNG (base64 data URL) or SVG, with size, margin, colours and error correction. Rendered on our server. For Wi-Fi pass wifi_ssid + wifi_password; for Solana Pay pass a solana: URI as text. Price: free. Errors: returns |
hash_encode | Hash data (SHA-256/512, SHA3, Keccak-256, BLAKE2, MD5, SHA-1, RIPEMD-160, HMAC) and convert between utf8, hex, base64, base64url and base58 — exact, in one call. Useful for signatures, content addressing, EVM selectors (keccak of a function signature), and decoding blobs agents are handed. Input can |
json_schema_validate | Validate JSON data against a JSON Schema (draft-07/2019-09/2020-12, formats like email/uri/date-time) and get every error with its exact path — check tool I/O before acting on it. Ajv, strict about types, all errors reported. Pass data and schema as JSON values (or JSON strings). Price: free. Errors |
cron_explain | Explain a cron expression in plain English and list its next N run times in any time zone — catch a schedule mistake before it fires at 3 am. Supports 5-field and 6-field (seconds) cron, ranges, steps, L/W/#, and nicknames (@daily, @hourly…). Price: free. Errors: returns isError with a message for i |
markdown_convert | Convert Markdown to clean HTML (GitHub-flavoured: tables, task lists, fenced code) or HTML back to Markdown. marked for md→html, Turndown for html→md. Scripts/styles are dropped on html→md. Price: free. Errors: returns isError with a message for invalid input or an upstream failure (not charged). |
text_diff | Diff two texts: unified diff (patch format), a line/word-level change list, and similarity % — compare versions of a doc, config or code. jsdiff. mode=lines gives a unified patch; mode=words gives word-level changes for prose. Price: free. Errors: returns isError with a message for invalid input or |
unit_convert | Convert between units of length, mass, volume, temperature, speed, area, time, data size, energy, power, pressure, frequency and more — or list every unit a value converts to. Exact conversion tables (convert-units). Use abbreviations: m, km, mi, ft, kg, lb, oz, l, gal, C, F, K, km/h, mph, knot, B, |
jwt_decode | Decode a JSON Web Token's header and claims, show issued/expiry times in plain dates and whether it has expired — optionally verify an HS256/384/512 signature with a secret. Decoding does not need the key. Never paste production secrets into third-party tools you do not trust; verification here is l |
random_gen | Cryptographically secure randomness: UUID v4/v7, passwords, API-key-style tokens, integers in a range, dice, coin flips, or a fair shuffle / pick from a list. Node's CSPRNG. Output is generated fresh per call and never stored or logged. Price: free. Errors: returns isError with a message for invalid |
text_stats | Count characters, words, sentences, lines and paragraphs, estimate LLM tokens, reading time and readability (Flesch), and pull out every URL, email, @handle, #tag, number and crypto address. Token count is an estimate (~4 characters per token for English; code and non-Latin scripts differ). Extracti |
