Terms of Service

Last updated 2026-04-18 · Short version, no surprises.

What Zero is

Zero is a skill runtime. You call skills via HTTP, email, or the @ protocol; each call produces a signed trace.

Beta status

Zero is in active development. APIs may change without notice. We try to preserve the @ protocol and trace shape, but reserve the right to break things before 1.0.

Your responsibility

• Keep your private key safe. Lost-key recovery is via M-of-N guardian sigchain, not a password reset.
• Don't abuse the service (spam, DoS, scraping copyrighted content at scale, CSAM, etc.).
• Respect third-party provider terms — LLM calls pass through to OpenRouter/Doubao/etc., and their limits apply.

Money

• Credits are 1:1 with USD. No conversion fees, no expiration.
• Refunds for unused credits honored within 30 days.
• Billing details: /billing.

Liability

Zero is provided "as is." For mission-critical work, self-host or wait for the 1.0 SLA.
