HumanMirror Guard — free Safe Preflight SDK

Lightweight optional clients for LangGraph, CrewAI, Coinbase AgentKit, AutoGen and custom agents. They do not spend money, auto-install hooks or substitute for application authorization.

Python (no dependencies)

curl -fsSL https://humanmirror.fr/sdk/humanmirror_preflight.py -o humanmirror_preflight.py
python3 humanmirror_preflight.py

Node.js (ESM)

curl -fsSL https://humanmirror.fr/sdk/humanmirror-preflight.mjs -o humanmirror-preflight.mjs
node -e "import('./humanmirror-preflight.mjs').then(async m => console.log(await m.check('Synthetic: repeated billable action')))"

Each demonstration makes one preflight request. The anonymous allowance is up to three calls per 24 hours. There is no automatic wallet charge on exhaustion. Separate paid x402 continuation is 0.010 USDC on Base with explicit wallet approval.

Retry-safety evidence

Fizzl ran a synthetic HumanMirror lost-response case through the Fizzl Agent Wallet's retry logic in a mock harness (mocked seller and chain lookup): one authorization, two attempts, no second charge, final state settled_no_answer. This is a mock test, not a live HumanMirror payment, integration, partnership or endorsement. Inspect the public Fizzl test.
