Nova Agent Utility Network https://naun-staging.doubleminht.workers.dev/mcp

  • change_detect — WHEN: On-demand check whether a URL fingerprint changed since a prior observation (caller schedules repeats). OUTPUT: changed, material, observation_id, delta, finalUrl, timestamp. LIMITATION: Not a polling SKU; not visual AI; live fetch each observation; format-only may be changed=true material=false. PRICE: $0.005 USDC (Base Sepolia) via x402 per successful check. TESTNET/STAGING. Next (suggestion only, never auto-invoked): store observation_id; if material → web_fetch_clean / web_extract_json.
  • naun_capabilities — WHEN: Discover tools, prices, networks, limits before paying. OUTPUT: Catalog object (tools + limitations + prices). LIMITATION: Read-only staging catalog; never invents mainnet/commercial. PRICE: Free — never charges. Next (suggestion only): pick paid tool matching job; confirm Base Sepolia USDC.
  • naun_health — WHEN: Liveness / health before paid work or diagnosing connectivity. OUTPUT: Health JSON (environment, commercial_revenue_eligible=false, prices). LIMITATION: Liveness only — not a paid SKU; does not prove a URL is fetchable. PRICE: Free — never charges. Next (suggestion only): naun_capabilities then appropriate paid tool.
  • web_extract_json — WHEN: Need schema-shaped fields from a public page (often after web_fetch_clean). OUTPUT: data + fields_not_found (+ routing/hash metadata). LIMITATION: Deterministic E1 only; never fabricates; not browser fidelity; structured_data_rich not guaranteed. PRICE: $0.008 USDC (Base Sepolia) via x402 per successful call. TESTNET/STAGING. Next (suggestion only, never auto-invoked): refine schema / web_fetch_clean inspect → change_detect.
  • web_fetch_clean — WHEN: Need cleaned public page (title + Markdown) without a browser. OUTPUT: title, markdown, finalUrl, retrievalTimeMs. LIMITATION: STANDARD HTTP only; no browser/JS render/PREMIUM/RENDERED; JS-heavy = best-effort SSR/HTML. PRICE: $0.003 USDC (Base Sepolia) via x402 per successful call. TESTNET/STAGING. Next (suggestion only, never auto-invoked): web_extract_json → change_detect.
