All projects on Base matching “check”

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. Re-run for each release or evidence change; sustained CI users can switch to the 30-day Release Guard pass.

No accidental wildcard CORS evidence record fetches current public evidence from the supplied target and evaluates the documented criterion. It returns the observation, threshold, verdict, exact evidence source, limitations and a mode-specific action. The check is passive: no login attempt, payload injection, exploit, purchase, form submission or load test is performed.

Before an AI agent trusts or pays a public API, inspect its public machine-readable evidence and x402 readiness. Submit a public HTTPS domain to check its agent card, OpenAPI, robots policy, and settlement-aware x402 signals, or submit a Base address for public onchain evidence. Returns a timestamped JSON report; not a security or compliance audit.

Pay once and get a field-by-field diagnosis of the payment your client signed (amount, recipient, validity window, clock offset, nonce, EIP-712 signature) and of the request that arrived, plus the facilitator's verify and settle results. Base mainnet payments get the full diagnosis; Base Sepolia payments get a preview with the status of each check only.
