What are this country's headline economics? World Bank time series for GDP, GDP per capita, population, inflation, unemployment, life expectancy, CO2 per capita or internet penetration, by plain-English alias or raw indicator code

Which earthquakes have just happened? Recent USGS events worldwide or within a radius of a named place, with magnitude, depth, tsunami flag and felt reports

Which days are public holidays in this country? Full year of national and regional holidays with local names and a past/upcoming flag — date arithmetic an agent cannot infer from a calendar alone

Levenshtein edit distance (insertions, deletions, substitutions) between two strings, plus a normalized similarity in [0,1]. Operates on Unicode code points.

Hamming distance — the number of positions at which two EQUAL-LENGTH strings differ — plus a normalized similarity. Strings of unequal length are a clean 400.

Damerau-Levenshtein distance — like Levenshtein but also counts adjacent transpositions as a single edit — plus a normalized similarity in [0,1].

Convert an MGRS grid reference back to decimal lat/lon on WGS84 (the coordinate of the grid cell's south-west corner at the given precision). Whitespace is ignored; a malformed reference is a clean 400.

Compute the geographic bounding box (west/south/east/north in degrees) of a slippy-map tile z/x/y, plus its Bing quadkey.

Map a WGS84 coordinate at a given zoom (0..30) to its slippy-map (XYZ / Google / OSM) tile x,y and its Bing quadkey.

Convert decimal lat/lon to a Military Grid Reference System (MGRS) string on WGS84. Precision is the number of digits per axis (1–5; 5 = 1-metre resolution, default 5).

Un-project Web Mercator (EPSG:3857) easting/northing in metres back to WGS84 longitude/latitude in degrees.

Report the ground resolution (metres per pixel, for 256-px tiles) and the OGC map scale denominator at a zoom level, optionally adjusted for latitude (default equator).

Convert a proleptic-Gregorian calendar date to its Julian Day Number (the integer count of days since JDN 0, 1 January 4713 BC in the proleptic Julian calendar).

Convert a decimal-degree latitude/longitude to degrees-minutes-seconds, with hemisphere letters and a formatted string for each axis.

Convert decimal lat/lon to a UTM coordinate (zone, latitude band, hemisphere, easting, northing) on WGS84, including the Norway/Svalbard zone exceptions. Defined for latitudes -80..84.

Encode a coordinate to a geohash and return its bounding box and 8 neighbors.

Encode a word with the Metaphone algorithm — more accurate than Soundex for English pronunciation.

Build source-bounded entity field coverage without inventing missing facts

Fact verification — returns verdict, confidence, current truth

Get an ERC-20 allowance with the owner's balance and a sufficiency verdict for the amount you plan to pull. ERC-20 allowance of a spender on an owner (USDC by default), with the owner's balance and, if you pass ?amount=, a verdict: i…

Assemble an ISO 8601 duration string from individual components (years, months, weeks, days, hours, minutes, seconds) and an optional sign. All components must be non-negative and at least one must be non-zero.

Parse an ISO 8601 duration such as 'P1Y2M10DT2H30M' into its components. Returns a normalized ISO string and totalSeconds — but totalSeconds is null when the duration contains years or months, because those are calendar-variable (use /v1/add or /v1/between for exact date math).

The radar and the safety check in one call: today's new Base pools above your liquidity floor, each with a safety verdict already attached (honeypot simulation, taxes, owner powers). One call instead of N+1

Evaluate one or more percentiles (0–100) of a numeric sample using linear interpolation between order statistics (the R-7 / Excel PERCENTILE.INC method). 50 is the median, 25/75 the quartiles.
