How this service works
Check if a number is prime.
Output
Returns a boolean or structured result indicating whether the submitted number is prime, along with the number itself. The response confirms primality (true/false) for the given integer input.
Example use cases
Verify prime for cryptographic key generation
“I'm generating RSA keys and need to confirm that 7919 is actually a prime number — can you verify that for me?”
Math homework primality check
“My kid is doing a number theory assignment — is 561 a prime number or not?”
Filter prime candidates in a sequence
“I've got the number 104729 from a random generator — can you check if it's prime before I use it?”
Technical details
Endpoint
POSThttps://sovereign-x402-zeta.vercel.app/api/v1/prime/check?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a quick, on-demand primality check for a single integer and are operating in an agentic or automated context that already handles x402 micropayments. Ideal for workflows where math validation is a step in a larger pipeline (e.g., cryptography, number theory tasks, educational tools) and you need a reliable hosted check without running local code.
Side effects
- Missing or malformed 'number' field in request body returns a 400 error
- Non-integer or negative number input may result in a validation error
- Payment not provided or invalid USDC transaction leads to 402 Payment Required
- Network timeout on the Vercel serverless function results in a 504 error
- Very large integers may exceed computation limits or timeout
