OT/ICS patch feasibility for a CVE. Pass ?id=CVE-XXXX-XXXX. Returns patch availability, OT-safe workarounds, patch complexity per ICS layer, estimated downtime, safe-to-patch-live flag, deployment strategy, and risk-vs-disruption score 1-10.

Validate email shape (not mailbox existence). Call when you cheaply reject obvious non-emails before enrichment. Returns valid boolean for $0.001 USDC via x402 on Base. Shape only—not MX, SMTP, or ownership proof. No network, no keys, no retention. Results are advisory; the caller owns budgets, auth, and production controls.

Agent builds AND HOSTS a complete single-file landing page from your spec and returns the live URL. Pay-per-call in USDC on Base.

JSON tools: validate, format, minify, list keys, infer JSON schema. Pass ?op=&data=. Pay-per-call in USDC.

Active DAO governance proposals (ENS, Arbitrum, Uniswap, Compound, Optimism, Lido, Curve (Ownership), Curve (Parameter), Aave): Snapshot (off-chain signal) cross-checked against a direct read of the onchain Governor contract (source of truth). Not an aggregation of one third-party dashboard — a cross-check. The discrepancy field flags cases where the off-chain signal stays silent about something real happening onchain (confirmed on Arbitrum: a public tracker showed the DAO as archived while its contract had an active vote on 48M ARB). Optional dao query parameter filters to a single DAO.
