Tools (2)
get_sequenceFetch a single OEIS integer sequence by its A-number (e.g. "A000045" for the Fibonacci numbers, "A000040" for the primes). Accepts the A-number with or without the "A" prefix and zero-padding ("A000045", "45", and "000045" are all valid). Returns the full record: name, terms (data), comments, formulas, keywords, offset, author, and reference count. Use this to get the formula or mathematical description of a known sequence.
Parameters not published.
search_sequenceSearch the OEIS (On-Line Encyclopedia of Integer Sequences), the authoritative database of integer sequences. Identify a sequence from its first terms by passing a comma-separated list of integers (e.g. "1,1,2,3,5,8" finds the Fibonacci numbers), look up a specific sequence by A-number (e.g. "A000045"), or search free-text keywords (e.g. "prime gaps"). Returns up to 10 matching sequences per page with their A-number, name, terms, keywords, author, and offset. Use the start argument to paginate (10 results at a time).
