Every Hive receipt is one ML-DSA-65 signature (NIST FIPS 204) over the exact state an agent saw before it acted — produced in about 7ms and settled per receipt in USDC on Base. Choose a primitive below, run a real call against the live signer, and read the signed envelope back. No signup wall.
Keyless primitives sign for real in your browser — tap a card to load it into the console below. AFiR-family primitives are live behind an API key; ARSC is the settlement layer those receipts ride on.
This posts the exact request shown to the live Hive signer and renders the signed envelope it returns. Fail-closed primitives reject inconsistent input with a 400 — that is the point.
// Choose a primitive and press “Sign it live”.
Every primitive meters on the same ladder — a receipt is one signed envelope. Rates below are the default Standard signature; stronger tiers (PQ, MAX) carry the same volume discount on a higher base. Usage is uncapped: no monthly minimum, no ceiling — you pay for exactly what you sign. See the full signature × volume matrix. Roll-ups are free.
Lowest-friction hook-in: start free with an instant key, run on the live endpoints above, and switch to paid metering over x402 / USDC on Base when you cross the Build tier — same rail you just signed against. Sovereign and on-prem licensing is available for teams that need custom custody.
Grab a free key and keep signing on the same live endpoints, or talk to us about a license for high-volume and on-prem custody.
