stillos-clearance

Drop-in counterparty clearance for AI-agent frameworks. Before your agent pays or transacts with a counterparty, clear it in one line — OFAC SDN screen + live Base on-chain wallet signals fused into a CLEAR / REVIEW / BLOCK verdict, Ed25519-signed and backed by a real on-chain correctness bond with /dispute recourse.

x402 and A2A payments settle naked — no KYC, no chargeback. This is the preflight.

Install

pip install stillos-clearance

Use

from stillos_clearance import guard, require_clearance, crewai_guard, agno_pre_hook

# 1. Inline — raises ClearanceBlocked on BLOCK
guard(counterparty_name="Acme LLC", counterparty_wallet="0xabc…")

# 2. Decorator — gate any payment/transfer function by default
@require_clearance()
def pay(amount, counterparty_name=None, counterparty_wallet=None):
    ...

# 3. CrewAI — gate a BaseTool so it refuses sanctioned/risky counterparties
crewai_guard(my_payment_tool)

# 4. Agno — pre_hook that clears the counterparty in run metadata before the agent runs
agent = Agent(..., pre_hooks=[agno_pre_hook()])

block_on_review=True treats REVIEW as a hard stop (default: REVIEW is allowed).

Config

• STILLOS_CLEARANCE_URL — override the endpoint (default: the live notary).
• Free tier applies per agent/day; past it the endpoint returns HTTP 402/429 with x402 payment terms, and is_allowed() treats a paywalled response as not cleared.

Why bonded

Every verdict is backed by real USDC staked on-chain (/notary/bond). A verdict proven wrong via independent re-run pays the disputant from the bond. Self-reported agent reputation has no money behind it; these verdicts do.
