Caesar Cipher (Educational)
Caesar shift cipher. Handy for puzzle agents, CTF helpers, or reversible toy encoding—not for secrets. Returns shifted text; educational cipher only, not cryptographic protection. $0.001 USDC per successful call via x402 on Base—deterministic first-party JSON, no API key, no subscription, and nothing is billed on structured validation errors.
One-command purchase
Run it from an agent.
No account or API key. AgentCash reads the 402 challenge, pays no more than the declared cap, retries the request and returns the result.
