Two calls, one key, and a usage meter you can audit. Your first key is a sandbox key — claim a cell, get a grant or a hold, verify the signed record.

API KEY · SANDBOXnone yet

A key scopes what an agent may claim. Start with one scoped to the sandbox — rotate any time.

A revoked key stops being honoured immediately, and every decision it ever made stays in the chain. Revocation is not deletion.

USAGE · THE METER IS THE CHAIN—

0 signed decisionsof 1,000,000

Usage is the count of signed entries in your chain, not a number we assert. Recompute it from a bundle and it matches to the decision.

create a key to pre-fill

from cascade import Layer

layer = Layer(key="…")           # create a key on the left
grant = layer.claim(
    cell="orchard/row-G14",
    agent="survey-drone-07",
    ttl_ms=2000,
)
if grant.ok:
    act(grant.cell)
    layer.release(grant)
else:
    grant.wait()                 # held — wait, do not race
print(grant.entry_hash)

→ create a key, then run your first claim
