The generate endpoint returns the first N terms of a sequence — fibonacci, lucas, primes, triangular, square, cube, factorial, catalan, pentagonal, tetrahedral, plus parameterised arithmetic (start, step), geometric (start, ratio) and powers (base). The contains endpoint tells you whether a given number belongs to a sequence (is 233 a Fibonacci number? is 21 triangular? is 97 prime?), using closed-form tests where they exist. Large terms are returned exactly as strings so nothing overflows. Pure local, no key."
