Number Theory GCD
x402
Number Theory GCD is a paid API for AI agents from numtheory.openverbs.com, paid per call via x402, $0.004/call, status unknown (last checked 2026-09-14).
Computes the Greatest Common Divisor (GCD) of two or more non-negative integers supplied as decimal strings.

How this service works
Greatest common divisor of two or more non-negative integers (arbitrary precision).
Output
Returns the computed GCD as a single non-negative integer — the largest integer that divides all provided input values without remainder. Accepts between 2 and 256 integers passed as decimal strings.
Example use cases
Simplify a fraction automatically
“I have the fraction 144 over 960 — what's the GCD of 144 and 960 so I can reduce it to lowest terms?”
Find shared divisor for scheduling
“Tasks repeat every 120 minutes, 90 minutes, and 75 minutes — what's the GCD of those three numbers so I can find the shortest common cycle?”
Cryptography key size validation
“I'm working on an RSA implementation and need to verify that the GCD of 17 and 3120 is 1 to confirm they're coprime — can you check that?”
Technical details
Endpoint
POSThttps://numtheory.openverbs.com/v1/gcdWhen to prefer
Choose this endpoint when you need a reliable, hosted computation of the GCD for 2–256 non-negative integers, especially in agent workflows requiring number-theory operations without spinning up local math libraries. Useful for fraction simplification, scheduling period calculations, and coprimality checks in cryptographic contexts.
Side effects
- Fewer than 2 values provided — validation error
- Non-numeric or non-decimal-string values — schema validation failure
- Values exceeding 256 items in the array — rejected by maxItems constraint
- Negative integers or non-integer strings — pattern mismatch rejection
- Network or payment authorization failure via x402 protocol
