Xynaptic Wind Forecast — 48h wind power forecast for a European region (wind speed at 100m, capacity factor estimate, gusts). Parameter: ?region=fr (or lat/lon). No API…
Scholarly paper search for research agents: journal articles, conference papers and preprints from Crossref (150M+ works) and arXiv in one call, deduplicated. Title, aut…
Encode a word with the Metaphone algorithm — more accurate than Soundex for English pronunciation.
Encode a word with Double Metaphone, returning a primary and a secondary code to capture alternate pronunciations (useful for non-English names).
Inspect a non-negative integer's bit structure: bit length, set-bit count (population count), trailing-zero count, power-of-two test, and hex/binary representations. An…
Circularly rotate a non-negative integer left or right within an explicit bit width (bits shifted off one end reappear at the other). The value must fit in `width` bits.…
Shift a non-negative integer left or right by `amount` bits. A right shift is logical (fills with zeros). A left shift grows freely unless a `width` is given, in which c…
Parse a document (json, json5, jsonc, yaml, xml, csv, tsv, toml, ndjson, ini, env, properties, plist or querystring) and validate it against a JSON Schema. Returns wheth…
Euler's totient φ(n) — the count of integers in [1, n] coprime to n — for a positive integer ≤ 10^15 (it is computed from the prime factorization).
Compute (base ^ exponent) mod modulus efficiently for arbitrary-precision integers. The modulus must be positive.
Miller-Rabin primality test (with witnesses that are exact for all 64-bit integers) on an arbitrary-precision integer. Returns { prime }.
South African Repo & prime rate (SARB repo rate and prime lending rate, South Africa's benchmark interest rates, with last MPC change date.) Clean cited JSON with offici…
