x402
Crypto Math RSA Arithmetic is a paid API for AI agents from crypto-math.x402tookit.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-10-27).
Analyzes RSA public key parameters (modulus bits, exponent validity, NIST strength) or demonstrates a toy RSA encryption/decryption round-trip using tiny primes.

How this service works
RSA public key arithmetic: modulus bits, exponent validity, NIST strength; or a labelled toy RSA with tiny primes.
Output
Returns a structured object with: verdict on key strength (pass/fail/degraded), modulus bit length, NIST security assessment, exponent validity, reasons for any failures, and in toy mode also phi(n), Carmichael lambda, private exponent d, ciphertext, decrypted value, round-trip boolean, and step-by-step educational explanation.
Example use cases
Validate production RSA key strength
“I have an RSA public key with modulus n=<big decimal number> and exponent e=65537 — run it in public mode and tell me if it meets NIST strength standards and what the bit length is.”
Toy RSA round-trip for a class demo
“Show me a toy RSA example using primes p=61 and q=53 with exponent e=17, and encrypt the message 65 so I can see the full encrypt/decrypt round-trip with all the steps.”
Educational RSA key generation walkthrough
“Walk me through RSA key generation in toy mode with p=89 and q=97, and show me phi, the Carmichael lambda, and the computed private exponent d.”
Technical details
Endpoint
GEThttps://crypto-math.x402tookit.com/rsa-arith?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to programmatically assess RSA public key security (NIST compliance, bit strength, exponent validity) or need an educational step-by-step RSA demonstration with small primes. Prefer this over general modular exponentiation endpoints when RSA-specific outputs like phi, Carmichael lambda, NIST verdict, and labeled key components are needed.
Side effects
- Invalid or malformed modulus (non-numeric or wrong format) returns an error
- Exponent fails validity checks (even, too small, or not coprime with phi) returns reasons array
- Toy mode primes p or q exceed 65536 limit returns validation error
- Toy mode message integer >= n causes an out-of-range error
- Missing required 'mode' query parameter returns schema validation error
- Modulus too large (>8192 bits) returns size limit error
