Maxwell defense requires Growth or higher
/v1/maxwell/challenge uses adaptive proof-of-work (Argon2id, decoys, dissipation receipts) to make adversarial input energetically irrational. The reference SDK is open-source at github.com/viridis-security/maxwells-defense — the hosted endpoint is gated to Growth+ for production-grade asymmetry and receipts.

Questions before you upgrade
Will my API key stay the same?
Yes. Your existing key keeps working; quotas update immediately on subscription activation.
Cancel anytime?
Yes for Starter / Growth / Scale (month-to-month). Enterprise is annual.
What about my in-flight calls when I hit the limit?
The rate-limiter responds with HTTP 429 + a retry-after header. Existing healthy requests complete; only the over-quota ones are rejected.
