GCD Calculator (Greatest Common Divisor)

Use this endpoint when you need a quick, on-demand GCD computation as part of an automated agent workflow that already handles x402 micropayments. Prefer this over implementing GCD logic yourself when you want a stateless, pre-built math microservice. Ideal for workflows involving fraction simplification, cryptographic checks (coprime detection), or any number-theory pipeline that needs GCD without spinning up compute.

• Missing or malformed input integers cause a 400/422 validation error
• Non-integer inputs (e.g. floats or strings) may be rejected
• Payment failure or insufficient USDC balance returns a 402 Payment Required error
• Both inputs being zero is mathematically undefined and may return an error or zero
• Network timeouts on the Vercel edge function
