Server instructions

Witnos: the witness for the x402 agent economy (counterparty and credit intelligence). Run Witnos before your agent pays anyone. Use token_risk before your agent buys, swaps, or LPs into a Base token, to check for rug, honeypot, or mint-authority risk; it scores the contract powers and the wallet that controls them. Use crest_score or agent_credit before paying, fronting, or extending service to an agent wallet, to check if it will pay or is about to drain to zero. Use check_counterparty or agent_preflight before any x402 payment, to see what is on the other side (real service, buyer, relayer, or treasury) and whether it is safe to pay. Use pm_counterparty to classify a Polymarket trader as sharp or dumb money. Use onchain_profile for a quick public snapshot of any Base address. Use crest_passport to mint a free persistent identity and memory; use crest_remember and crest_recall to store and recall tamper-evident memories across sessions; use crest_verify to check another agent's standing before you trust or pay it. All tools are free, read-only, and not financial advice. By Crest Deployment Systems.
