Page 93 of 169NanoID-style public IDs. Generate short URL-safe IDs for jobs, drafts, or idempotency keys without installing nanoid. Returns a random URL-safe id (size 4–64, default 21). $0.001 USDC per successful call via x402 on Base or Solana—first-party JSON from Delx (fresh each call; not a deterministic transform), no API key, no subscription, and nothing is billed on structured validation errors.
Convert colors between hex, rgb, hsl. ?color=#ff0000 or rgb(255,0,0)
Escape or unescape HTML entities. ?op=enc|dec&data=<text>
Convert Markdown to HTML (tables, fenced code). ?text=<markdown urlencoded>
Audit robots.txt + sitemap.xml of a site: rules, sitemaps listed, sitemap reachable, URL counts. ?url=<site root>
Google Trends interest by region/country for a keyword. ?q=casino&geo=&time=12-m
Google Trends related queries: top and rising search terms for a keyword. ?q=casino&geo=&time=12-m
Convert units: length, weight, volume, data size, temperature. ?value=100&from=cm&to=inch
Turn a string of phonetic words back into text ("Sierra Oscar Sierra" → "SOS"). Accepts common alternative spellings (Alpha, Juliet, Niner). Unknown words are clean 400s.
Decode international Morse code back into text. Letters are separated by whitespace and words by "/". Unknown Morse sequences are clean 400s.
Encode text into international (ITU) Morse code. Letters are separated by spaces and words by "/". Supports A-Z, 0-9 and common punctuation; unsupported characters are clean 400s.
Spell text using the NATO/ICAO phonetic alphabet (A→Alfa, B→Bravo, …), including digits and spaces (→Space). Characters with no phonetic spelling are clean 400s.
Current NBA standings by conference — wins, losses, win percentage, and conference rank for all 30 teams.
Validate any IBAN offline — mod-97 check digits, per-country structure, bank/branch extraction, and pretty formatting for ~80 countries — deterministic, instant, no upstream. A structurally invalid IBAN is a real answer: valid:false + findings naming exactly what failed. Pass iban as ?iban= (GET) or a JSON body (POST).
Look up public holidays for any country and year, check whether a specific date is a holiday, and calculate the next business day — so agents can handle scheduling, SLA calculations, deadline setting, and date-aware workflows without hardcoding country-specific holiday rules.
Translate text between languages — text translation API for short content: translate a sentence, chat message, or up to 500 words to English, Spanish, French, Chinese, or any of 30+ languages. Language translation with auto-detected source language, formatting preserved; returns the translation plus detected source. Machine translation via Claude Haiku for agents localizing content cheaply. For longer documents use /translate/long.
Detect the language of any text input using stopword-set matching and Unicode script analysis — returns the detected language, ISO code, a high/medium/low confidence level, and top alternative languages so agents can route multilingual content, trigger translation workflows, and classify text without a paid NLP API.
Instant text statistics — characters (with/without spaces), words, unique words, sentences, paragraphs, average word/sentence length, longest word, reading and speaking time. Deterministic, no LLM, no API key. For agents sizing content before summarizing, chunking, embedding, or posting. Pass text as ?text= (GET) or a JSON body (POST).
Translate many independent strings in one request — each with a caller ID preserved in the response — with per-item status, glossary and tone support, and partial success so one bad item never fails the batch, so agents can localize whole string tables in a single call.
Classify text into your own categories — zero-shot: supply 2–20 labels and Claude Haiku returns the best-matching category with confidence and per-label scores. Route, tag, triage, and detect intent or topic with your own taxonomy in one call.
Translate up to 2000 words between languages using Claude Haiku — auto-detects source, supports 30+ target languages, preserves formatting, for larger documents and articles. For short snippets use the cheaper /translate/short.
Turn event fields into a valid RFC 5545 .ics calendar file — handles timed and all-day events, escaping, line folding, and a deterministic UID for idempotent re-import — so agents can publish events that import cleanly into Google, Apple, and Outlook calendars. Add ?download=1 (or Accept: text/calendar) to receive the raw .ics file with a Content-Disposition attachment header instead of the JSON envelope. Pure compute, no LLM.
Convert any physical measurement — length, mass, volume, temperature, area, speed, pressure, energy, time, data storage & transfer rate, power, frequency, force, fuel economy (mpg/L per 100 km), angle. Auto-detects the category, handles US/imperial ambiguity, reports assumptions. Accepts natural-language queries ("what is 5 km in miles") and volume↔mass via density/substance. Deterministic and instant.
