How this service works
Number facts API: everything mathematically interesting about any integer — is it prime, its prime factorization, Fibonacci membership, perfect-square status, even/odd, binary and hexadecimal forms, Roman numeral, and digit sum. Computed locally, deterministic, instant. For quiz agents, content generation, validation, and the incurably curious.
Output
A structured response containing: primality (true/false), prime factorization list, Fibonacci membership flag, perfect-square status, even/odd parity, binary string, hexadecimal string, Roman numeral representation, and digit sum — all computed deterministically for the given integer.
Example use cases
Example prompt
“Tell me all the math facts about the number 360 — is it prime, what's its prime factorization, is it a Fibonacci number or perfect square, and what does it look like in binary, hex, and Roman numerals?”

Endpoint
POSThttps://x402.forgemesh.io/number-factsWhen to prefer
Use this endpoint when you need instant, deterministic, multi-faceted mathematical analysis of a single integer — especially for quiz generation, educational content, number trivia, or validation tasks where you need primality, factorization, Fibonacci/square membership, and base representations in one call.
Side effects
- Non-integer or unparseable input may return an error or default to 42
- Very large integers may exceed supported range
- Empty or missing 'number' field defaults to 42
- Floating-point or decimal values may be rejected or truncated
