Classify a caller-supplied operation claim against caller-supplied evidence under deterministic rules and return a machine-readable handoff receipt. Use this when an orchestrator needs a consistent completion state before accepting an agent's work. VERIFIED_COMPLETE means the submitted evidence supports the submitted claim; QSL does not independently observe the underlying real-world action.

Request an https URL and report whether it is reachable, its status, every redirect hop with timings, key and security headers (HSTS, CSP and others), and the TLS certificate with its issuer, the names it covers and the days until it expires. An unreachable URL is a result too, with the reason.

Validate JSON data or an API payload against a compact JSON schema and return deterministic validation results. Check required fields, value types, object structure, and structured agent inputs. Useful as a JSON validator for API responses, request payloads, and schema checks.

Use when an agent needs the best live price for a stock across venues before trading. For 1-10 tickers: perp mark and mid on trade.xyz (Hyperliquid), Aster, Lighter and OKX, xStocks and Ondo token prices per share, last US close, the session reference price, gap % vs it, cross-venue spread, best bid/ask and freshness. Unpaid calls get 402; bad or unknown tickers get 400/404 before any charge. Erro

Website HTTP and metadata inspection report

XML tier (deterministic, no LLM): verifies a claimed value lives at a named path in a public XML document, by independent double re-fetch. Use it for feeds and sitemaps; for JSON use /verify-json, for HTML use /verify. Paths address elements and @attributes (urlset.url[0].loc). String-exact; ambiguous or volatile values return unverifiable, never a guess. First 100 checks per client are free: rese

Tuned to over-report rather than miss. Returns the list bu
