sequence-identifier
Integer Sequence Identifier — Identifies an integer sequence from terms (a JSON array or pasted text), an OEIS A-number, a safe-parsed formula or recurrence, or a description, and leads with a verdict, confidence, A-number, formula, next terms and a next step. Searches the OEIS directly, then superseeker-style (differences, partial sums, gcd, ratios, binomial, Euler, leading terms, plus a search without the last two terms to f

}Input Schema
| Name | Required | Description | Default |
|---|---|---|---|
| count | No | How many terms to expand from the formula; default 20. | |
| start | No | Index n of the first expanded term; default 0. | |
| terms | No | Integer terms, 4 to 60, each at most 40 digits. Pass values beyond 2^53 as decimal strings. | |
| aNumber | No | Alternative to terms: an OEIS A-number (A000108) or oeis.org URL. The entry is fetched and its data searched for related sequences; returns its name, formulas and next terms. | |
| explain | No | Ask a model for a one-sentence explanation drawn only from the matched OEIS entry; its quote is verified in code, otherwise the entry name is returned. Default false. | |
| formula | No | Alternative to terms: a closed form in n such as "binomial(2*n,n)/(n+1)", or a recurrence such as "a(n) = a(n-1) + a(n-2)" (with initialTerms). Operators + - * / % ^, functions binomial fact abs gcd min max floor mod. Evaluated by a safe parser, never eval; every term must be an integer. | |
| termsText | No | Alternative to terms: the terms pasted as text, separated by commas, spaces or semicolons (for example copied from a spreadsheet, a paper or an OEIS data line). | |
| description | No | Alternative to terms and formula: a plain-language description. A short description that names an entry (up to 4 content words, all in the entry name, e.g. Catalan numbers) is resolved by OEIS text search with no model; otherwise one fast model call proposes terms and keywords, which OEIS then confirms. | |
| initialTerms | No | Seed values a(start), a(start+1), ... for a recurrence formula. |
