How this service works
Calculate Euler totient function phi(n) for a given positive integer n.
Output
Returns the Euler totient value φ(n): the count of positive integers from 1 to n that share no common factor with n (i.e., are coprime to n). For example, φ(12) = 4 because 1, 5, 7, and 11 are coprime to 12.
Example use cases
RSA cryptography key validation
“I'm working on RSA encryption and need to know the Euler totient of 3233 — that's p×q where p=53 and q=61. Can you compute φ(3233) for me?”
Number theory homework problem
“For my discrete math assignment, I need to find how many integers from 1 to 100 are coprime to 100. Can you calculate Euler's totient phi(100)?”
Modular arithmetic computation
“I need to compute Euler's totient of 4096 to figure out the modular inverse in my cryptographic protocol. What is φ(4096)?”

Endpoint
POSThttps://sovereign-x402-zeta.vercel.app/api/v1/sequence/totientWhen to prefer
Use this endpoint when you need a fast, pay-per-call computation of Euler's totient function without spinning up your own number-theory library or server. Ideal for one-off calculations in cryptographic workflows, educational math tools, or any agent pipeline needing φ(n) as an intermediate step.
Side effects
- Non-positive integer input (n ≤ 0) may return an error or undefined behavior
- Non-integer or floating-point input may be rejected
- Very large integers may cause timeout or overflow
- Missing required 'input' body field returns a validation error
