Full edition of the AI Agent Setup Checklist v1.4: 8,861 words of Markdown in 16 sections. Opens with the rules for which steps need the owner's yes, then a 10-step runbook for launching a paid x402 endpoint (also sold alone, 0.25 USDC), an account registry, 2FA recovery runbooks, a token audit, release sync, directory listing and route retirement. Vendor facts sit in one dated appendix (October 2

Latest available Türkiye central government debt plus a comparable annual history from the World Bank World Development Indicators API, with source, lag and revision caveats. Purpose: Give an autonomous agent a normalized, directly sourced Türkiye central government debt series without forcing it to understand World Bank indicator codes or response shapes. 24-hour freshness target; missing evidenc

Check an x402 endpoint before paying it. Give it any x402 URL: it makes the unpaid request, decodes the 402 challenge, reads the origin's .well-known/x402 and openapi.json, inspects the payTo address on-chain (USDC inflows, distinct senders, EOA vs contract vs smart-wallet delegation), and returns a 0-100 trust score with buy/watch/avoid plus the evidence and the penalties behind every point ...

AI agent action safety: one-cent deterministic preflight for every consequential agent command. Returns risk, matched rule ids, and an exact machine-readable escalation call: full DestructGuard evidence for medium risk or the complete Action Safety workflow for high and critical risk.

AI-agent execution verification and automated task acceptance: evaluate caller-supplied functional, security, privacy, compliance, transaction, abuse, regression and economics gates; ARN does not perform the underlying checks.

Page text is flagged untrusted so an agen
