Caesar shift cipher
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.
