Resolve a single code point (given as 'char' or 'codepoint') to its name, general category, block, script and plane. Provide exactly one of the two inputs.

Reverse lookup: resolve a Unicode character name (e.g. 'SNOWMAN', 'CJK UNIFIED IDEOGRAPH-4E2D', 'HANGUL SYLLABLE GA') to its code point. Loose whitespace/case matching. An unknown name is a successfu…

UUIDs on demand: version 4 (random) or version 7 (time-ordered, sortable), up to 100 per call. Use it when an agent needs identifiers for records, requests or files, or a sub-cent call to test an x402 client end to end before buying anything larger.

Generate cryptographically secure unique IDs: UUID v4, time-sortable UUID v7, ULID, NanoID, hex, base58 or prefixed tokens (e.g. ord_...), up to 1000 per call.

Convert a measurement without losing declared uncertainty: one decimal value and standard uncertainty across supported length, mass, time or temperature units using exact rational scale/offset arithmetic. No unit guessing, physical validation or expanded uncertainty. New modular adapter: retained result recovery for 24 hours, minimal receipt metadata for 90 days. Existing live route unchanged.

Convert a measurement without losing declared uncertainty: one decimal value and standard uncertainty across supported length, mass, time or temperature units using exact rational scale/offset arithmetic. No unit guessing, physical validation or expanded uncertainty.

Convert units of length, mass, volume, area, speed, temperature, data (KB vs KiB), energy, pressure, time and power, metric and imperial, with exact factors.

Convert a value between units of length, mass, temperature, volume, area, speed, time, data, pressure, energy, power, angle, frequency - every unit the retired convert-* endpoints handled (e.g. miles, kilometers, kilograms, pounds, stones, us-gallons, liters, fahrenheit, psi, bar, kilopascals, kilowatt-hours, joules, btu, horsepower, and imperial Russian versts, sazhens, arshins, poods and funts).

Convert a value between units of length, mass, volume or temperature (C/F/K).

Convert a value between units — length, mass, volume, temperature, area, speed, pressure, energy, power, digital storage, time, angle, frequency and more. Unknown units or a conversion between incomp…

List the supported units and their metadata (abbreviation, measure, system, singular/plural names), optionally filtered to a single measure — a discovery endpoint for choosing valid `from`/`to` value…

Convert length, mass, volume, data-size, time, speed, or temperature between units.

Upgrade any agent room in APEX Agent City (Arc) by one level: Gilded, Gallery, Garden (grows TOMATO), Club, Penthouse; upgraded rooms wear gold halos over their tower. Pass ?agent=1 and an optional &note=. A room already at level 5 is refused before you pay.
