General Utilities x402 offerings

JSON micro-tool for agents: GET ?url= (or POST url / image_base64) → local Tesseract OCR (English-first): text, word_count, confidence, width/height, fetched_at, timing_ms. COGS=0 — no upstream OCR API key. Demand-matched OCR class (competitors ~$0.005–$0.012). Brand: geld machen. x402 $0.01 Base USDC.

Generate fresh random UUID v4 identifiers, one or many in a single call. Cryptographically random, instant. Use for unique ids, request keys or fixtures.

Convert decimal degrees to degrees/minutes/seconds, or DMS back to decimal degrees.

Ray-casting point-in-polygon test (planar approximation - fine for city/region-scale polygons).

Tests planar point containment with the even-odd rule. Missing facts are returned as null and named in unavailable_fields where applicable. Derived values disclose their method; source-backed values disclose source, time window and age.

Calculates planar polygon area and centroid in caller-declared coordinate units. Missing facts are returned as null and named in unavailable_fields where applicable. Derived values disclose their method; source-backed values disclose source, time window and age.

Euclidean, Manhattan and Chebyshev distance between two 2-D points.

Area, perimeter and diagonal of a rectangle from its width and height.

Diameter, circumference and area of a circle from its radius.

Give it a longitude and latitude and it answers with the IANA timezone identifier (America/New_York), the UTC offset in force there right now, whether daylight saving is currently in effect and by how much, the local wall-clock time, and the zone's standard offset. Pass an optional ISO 8601 `at` instant to ask about any moment between 1900 and 2100 instead of now, which is what you want when scheduling something months out across a DST boundary. Parameters go in the query string: this is a GET, there is no body. Two halves, with different vintages, and the difference matters. The offset and the DST rules come from the runtime's own timezone database and are current: a rule change reaches this endpoint when Cloudflare updates ICU, with no redeploy here. The *boundaries* come from tz_world (efele.net), CC0 1.0 and derived from VMAP0, a public-domain US government product. That map was frozen at tzdb 2016d in May 2016, and this catalog sells public-domain and permissively-licensed data only, which is why it is used rather than the current OpenStreetMap-derived alternative. What the vintage costs, measured against IANA's own coordinates for all 312 zones in zone1970.tab rather than estimated: 293 agree. Of the 19 that do not, 7 are Antarctic research stations, which this map does not cover at all and which fall back to the open-water rule; 7 more return a different identifier for the identical offset and DST all year (Australia/Brisbane for Australia/Lindeman, America/Regina for America/Swift_Current, and five like them), so the time is right and only the name is old. That leaves four regions where the answer is up to one hour wrong because the zone was split after 2016: Chilean Magallanes and Aysen (answered as America/Santiago rather than America/Punta_Arenas or America/Coyhaique), the Mexican border municipalities around Ciudad Juarez, Saratov Oblast in Russia, and the weeks each spring when Asia/Hebron and Asia/Jerusalem change on different dates. If you query insid

Parse a coordinate string into decimal lat/lon. Accepts a plain decimal pair ('40.4462, -79.9822') or DMS with hemisphere letters ('40°26'46"N 79°58'56"W'). Anything unrecognized is a clean 400.

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

Convert a UTM coordinate (zone, hemisphere, easting, northing) back to decimal lat/lon on WGS84.

Scores how readable a German text is: Flesch Reading Ease (Amstad adaptation) plus the four Wiener Sachtextformel variants. Returns both scores, the underlying counts (sentences, words, syllables, sentence length) and the formulas, so the result can be recomputed. Syllable counting is a disclosed approximation (vowel-group heuristic), not an official certification.

Translation tuned for skilled-trade work: HVAC, refrigeration, electrical and construction terms stay correct instead of collapsing into a generic word. Handles text typed fast without accent marks.

Japanese public holidays for a given month — national holidays, substitute holidays (振替休日), and Golden Week. These holidays shift gotobi dates and close Tokyo markets, affecting JPY liquidity. Complete coverage through 2099 with substitute holiday rules. Accepts USDC payments on Base and Solana

Is today a Japanese public holiday? Returns holiday name in Japanese and English. Uses JST timezone for accurate date determination. Covers all national holidays, substitute holidays, and special observances. Essential for FX trading session validation and holiday-aware scheduling. Accepts USDC payments on Base and Solana

Monthly gotobi calendar with all 6 dates (5th, 10th, 15th, 20th, 25th, last business day) and automatic weekend/holiday adjustments. No public database of adjusted gotobi dates exists — building one requires Japanese holiday law knowledge through 2099. Accepts USDC payments on Base and Solana

Next upcoming Japanese public holiday with countdown — holiday name, exact date, and days until. Plan around Tokyo market closures and gotobi day shifts. Complete coverage through 2099. Accepts USDC payments on Base and Solana

Applies a fixed, published logistic equation to aggregate caller-supplied features and reports an estimated turnout range. It is an untrained scenario heuristic, not a calibrated election forecast, individual propensity score, or basis for voter targeting.

Sorts unique scalar key/value entries through canonical JSON serialization and computes SHA-256. It verifies byte-level agreement with an optional claimed digest only; it does not prove block inclusion, timestamp, signer identity, or chain consensus.

Splits caller-supplied proposal text into sentences, scores each sentence by normalized non-stopword frequency, and returns the highest-scoring sentences in source order. It does not infer unstated intent, verify claims, or produce an abstractive interpretation.
