Husky — Storm — High-energy exploration companion for risk-taking and adventure motivation.

One weather instrument's 247 rank: its place in its state today, reports due and received, timeliness, longest silence and its history. This call needs key, the instrument as net:<STATE>_<NETWORK>:<id>; the example below answers for real. Every address this endpoint serves is listed one at a time at https://stormstation247.com/api/x402.

One radar or forecast picture read state by state: each state's highest value and where it stands, or its range and mean, highest first. This call needs picture, one of the 31 pictures the input schema names, as the radar page names them; the example below answers for real. Every address this endpoint serves is listed one at a time at https://stormstation247.com/api/x402.

US stock trading halts now and earlier today (Nasdaq, NYSE, NYSE American): reason in plain English, halt time, resume times, status. Filter by tickers or get all. Refreshed every minute.

Read any public web page as clean, LLM-ready Markdown plus metadata (title, description, author, dates, canonical). Respects robots.txt.

Is this npm or PyPI package safe to install? Exists or made-up name, malicious-package reports, known vulnerabilities for the version (with fix), deprecated/yanked, age, install scripts, downloads, typosquat look-alikes. Verdict with reasons.

Which paid API should your agent call? Describe the need ("web search", "weather forecast", "verify an email") and get the top x402 endpoints ranked by repeat paid use (calls per wallet, not one-off sampling), recency and price, each checked live, with URL, price and why.

Is this email address or domain legitimate? Verdict with reasons: syntax, role address, disposable or free provider, MX / null MX, mail provider, SPF, DMARC, website live, domain age. No mailbox probing.

Should your agent pay this endpoint, seller or wallet? Verdict (ok_to_pay / caution / dont_pay) from live payment terms, its x402 Bazaar listing and paying wallets, payment-address match, real-USDC check, price vs. similar tools, and seller domain age.

Is this store ready for AI shopping agents (ChatGPT/ACP, Google/UCP)? Score, readiness level and fix list.

Vendor security & privacy profile from a domain: claimed certifications (SOC 2, ISO 27001…), AI training on customer data (with quote), subprocessors, DPA, data residency, security features and a transparency score.

Use when a topic, goal, problem or question needs a quick set of ideas that are already ranked: 3-5 ideas each scored 1-10 on three criteria that fit the kind of brainstorm (business: market size, ease to start, profit potential; problem: impact, feasibility, cost), an overall score, optional sub-ideas under the top 3 (depth=2), and a link to an interactive bubble map of the result. Errors: 400 bad_input, 502 model unavailable. Failed calls are not charged.

Deterministic domain risk and trust evaluation returning ALLOW / REVIEW / BLOCK. Decision for observed evidence; external evidence may change between calls. Uses DNS, RDAP, TLS, HTTP/redirect, URLhaus threat reputation, local indicators. Read-only: external read queries only, no action on domain, no persistence, limited cache. USE WHEN: decide whether domain is safe enough for interaction, onboarding, outreach, or payment. DO NOT USE WHEN: consolidated domain health/operational inspection (use

Strait of Hormuz shadow-fleet risk screen: the live-AIS vessel population (vessels seen on AIS within the last activeWindowHours, currently 1.5) ranked worst-first, each hull with its risk band, the typed reasons behind it (ofac_sdn, ais_dark, foc_tanker, imo_spoofed), which sanctions bodies list it (US OFAC and/or UK/FCDO), and a lastSeenAt timestamp (when the hull was last listed, not necessarily its last true AIS fix) so listing recency can be checked per row. A transparent rules engine (not ML) fusing OFAC + UK sanctions, live AIS, AIS-dark gaps, and spoofed-IMO detection into one compliance-grade screen. counts cover the screened population, that is every hull seen on AIS inside the active window, not every hull ever tracked; vessels lists only the flagged hulls (high + moderate) by default, ?all=1 adds the cleared low-band hulls. Quality-gated on live AIS; flags are best-effort from the MMSI MID (ITU-T M.585). Because the screen is bounded to the active AIS window, an ais_dark re

Strait of Hormuz bunker & marine-fuel feed: current VLSFO, IFO380, and MGO prices ($/tonne) for Fujairah (the world's #2-3 bunkering hub, just outside the strait and the physical fueling alternative when transit is disrupted), benchmarked against Singapore and Rotterdam, plus the derived Fujairah premium over each comparison hub. The physical-commodity read on Hormuz stress that the Brent and insurance signals do not capture.

Strait of Hormuz war-risk transit premium nowcast: a live MODELED war-risk insurance multiple (Nx over the peace baseline, on the published 1x-80x scale) for moving a tanker through the strait, recomputed every 5 minutes from throughput deviation (IMF PortWatch), the escalation forecast (Polymarket + Kalshi + Manifold + Brent-WTI spread), crude implied volatility (OVX), and event pressure (news and maritime RSS feeds, the PGSA incident feed and GDELT). The standing straits.live insurance-estimate multiple is carried only as a static reference (it is set manually and changes infrequently); the modeled figure is the live signal, not a divergence from that anchor. Returns a band, a curated VLCC war-premium band ($/voyage, estimated separately from the modeled multiple and not derived from it), per-driver detail, and a confidence that degrades on stale feeds or thin market volume. A modeled situational-awareness indicator, not an insurance quote.

Run a bounded declarative historical spot strategy backtest.

Grid-search up to 50 parameter combos of a backtest strategy; ranks by worst-half (H1/H2) return with neighbourhood smoothing, flags overfitting, and recommends the most robust parameters rather than the best-fit ones.

Stripe Webhook Review — Reviews ONE Stripe webhook handler (the route code, in any language or framework) for the five mistakes that let a forged or repeated event move money, grant access or ship goods, and lists only those, one line each with a fixed code, the place, why it is dangerous and the fix - or exactly No findings. It catches a body parsed or re-serialized before the signature is checked, a handler that never checks the signature, a recency tolerance switched off or set huge, no reco…
