Primality Check for Agents

Primality check. Call for teaching demos, ID heuristics, or lightweight number filters (bounded integers). Returns whether n is prime with a clear boolean field. $0.001 USDC per successful call via x402 on Base or Solana—deterministic first-party JSON, no API key, no subscription, and nothing is billed on structured validation errors.
