Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

Atlas United address-level storm data. Products: ML Storm Forecast by Address (dataset=risk, forecasts 24 hours to 10 days ahead, could happen), Model-Based Weather by Address (dataset=weather), Model-Based Hourly Forecast by Address (dataset=weather with hours_ahead), Storm History by Address: Reported and Radar-Detected Events Since 2003 (dataset=history), Past Storm Leads by Address: Reported and Radar-Detected, Last 365 Days (dataset=storms). Storm data means a storm was reported or radar-detected near an address; it is not a property inspection or damage assessment. Without a key, every data tool returns the exact price quote (count and price) and a pay link; with a key (or x402 payment) it returns the data. Only the menu (get_weather_data with no arguments) is free. Start with a quote (addresses=false) unless the user asks for the paid data. Never invent numbers. Every quote begins with a note with the count, price and payment link: pass it on to the user. Never present quote numbers as the address list. License: own use only; no resale, redistribution or AI training. HARD RULE, NON-NEGOTIABLE: when the user asks to see the menu, list what is available, list all datasets, or asks any variant of what can I get / what do you offer / show me everything, call get_weather_data with NO arguments and output that ENTIRE raw response back to the user VERBATIM, every dataset, every field, every quick_pick, every example call, in full. Do NOT summarize. Do NOT paraphrase. Do NOT select a subset or pick highlights. Do NOT compress it into your own words or a shorter bullet list. If the user says list all, list everything, or show me the full menu, that means reproduce the complete response exactly as received, formatted clearly, nothing omitted. A summarized or partial menu is a wrong answer even if it sounds complete.

get_weather_data — Atlas United data, all datasets (advanced / multi-county)
Advertised by the server during the last successful anonymous check.
Advertised read-onlyOpen-world

CATCH-ALL and PAID-PULL tool. Prefer the dedicated tools below when one fits (get_storm_history: one county, past 365 days; get_risk_forecast: one county, next 24 hours to 10 days; get_address_report: one address, past 365 days; get_property_storm_history_report: one address, 2003 to present; get_current_weather: one point, now to 48 hours). Use THIS tool for: every PAID address-level pull (set addresses=true), county coverage ($0.0002), facilities, wildfire (county-level), at_risk, daily, a counties multi-county rollup (comma-separated, max 15), hazard_score ($0.50), or any parameter the dedicated tools do not expose (radius_mi, date_of_loss, window, months, category, limit, kind, details, hours_ahead). Datasets: ML Storm Forecast by Address (risk), Model-Based Weather by Address (weather), Model-Based Hourly Forecast by Address (weather with hours_ahead), Storm History by Address: Reported and Radar-Detected Events Since 2003 (history), Past Storm Leads by Address: Reported and Radar-Detected, Last 365 Days (storms). Without a key, the tool returns the exact price quote (count + price) and a card pay link; with a key (prepaid from $1 at https://atlasunited.io/api) or an x402 payment, it returns the data. Call with no arguments for the free full menu. License: own use only; no resale, redistribution or AI training. HARD RULE when called with no arguments: this returns the full menu. Output that entire raw response back to the user verbatim, every dataset, every field, every example. Do not summarize or paraphrase. A shortened version is wrong even if it looks complete.

Advertised by the server during the last successful anonymous check.
Advertised read-onlyOpen-world

COUNTY LEVEL, PAST 365 DAYS. Past Storm Leads by Address: Reported and Radar-Detected, Last 365 Days. Use when the question is how much storm activity a county has had in the past year. Without a key, returns the exact price quote (address count and price at $0.05/address) and a pay link; with a key it returns the data. County grade and counts by storm type are a paid County Summary (summary=true, $0.02 per county). Input is state plus county, never a street address. Not for one property (use get_address_report), not for the 2003-to-present record (use get_property_storm_history_report), not for future storms (use get_risk_forecast). Not a damage assessment. For the paid address-level list, call get_weather_data with dataset=storms and addresses=true ($0.05 per address; pay with an Atlas United API key, x402, or the card pay link).

get_risk_forecast — ML Storm Forecast by Address
Advertised by the server during the last successful anonymous check.
Advertised read-onlyOpen-world

COUNTY LEVEL, FUTURE (next 24 hours to 10 days). ML Storm Forecast by Address. Use when the question is which storms could affect a county soon. Without a key, returns the exact price quote (count of addresses in the forecast path and price at $0.05/address) and a pay link; with a key it returns the data. County grade and counts by storm type are a paid County Summary (summary=true, $0.02 per county). Input is state plus county. Per-peril machine-learning models, refreshed 4 times a day. Could happen, not will. Not for past storms (use get_storm_history, get_address_report or get_property_storm_history_report) and not for current weather (use get_current_weather). The paid pull (addresses=true, $0.05 per address) returns one record per address with structure_value (USD replacement cost), people (estimated occupants), full_address, lat, lon, county, storm_type, forecast_time and risk_label. For the paid pull, call get_weather_data with dataset=risk and addresses=true (pay with an Atlas United API key, x402, or the card pay link).

get_property_storm_history_report — Storm History by Address: Reported and Radar-Detected Events Since 2003
Advertised by the server during the last successful anonymous check.
Advertised read-onlyOpen-world

ONE PROPERTY, 2003 TO PRESENT. Storm History by Address: Reported and Radar-Detected Events Since 2003. Use when the user wants the full citable record for a single address, or a date-of-loss lookup: 11 event categories (hail, wind, flood, lightning, tornado, hurricane, winter storm, extreme heat/cold, drought, wildfire, coastal) in one report. Input is a street address or lat/lon. Not the 365-day snapshot (use get_address_report) and not a county summary (use get_storm_history). Without a key, returns the exact price quote (report-line count and price) and a pay link; with a key (or x402 payment) it returns the data. Paid report: $0.05 per line, no minimum (zero matching lines = $0.05). Optional date_of_loss anchors the report around one date and lists the events reported or radar-detected on and around it, for reference; it is not a determination of whether any claim is valid. Address and date of loss are sent in a POST body, which keeps them out of URLs and logs.

ONE POINT, NOW TO 48 HOURS. Model-Based Weather by Address: point weather for any U.S. coordinate or street address, with current conditions, active severe weather alerts and a short-term rain outlook. Use for what the weather is or will be at a location; add hours_ahead=0-48 for Model-Based Hourly Forecast by Address. Not for storm history or storm-risk forecasts (use get_address_report, get_property_storm_history_report, get_storm_history or get_risk_forecast). Without a key, returns the exact price quote ($0.0002) and a pay link; with a key (or x402 payment) it returns the weather data, billed $0.0002 per call (not per address).

get_address_report — Property Snapshot by Address (365-day past storm leads plus county forecast label)
Advertised by the server during the last successful anonymous check.
Advertised read-onlyOpen-world

ONE PROPERTY, PAST 365 DAYS. Property Snapshot by Address: Past Storm Leads plus County Forecast Label. Use for recent storms at one exact address: its own reported and radar-detected storm events within a tight radius (about 150 m), with the county's current forecast label as secondary context. Input is an address with county and state, or lat/lon. Without a key, returns the exact price quote ($0.05) and a pay link; with a key it returns the data. Not the full archive (use get_property_storm_history_report, Storm History by Address, which searches a wider 5-mile radius so counts will differ), not a county summary (use get_storm_history), and not forecasts (use get_risk_forecast, ML Storm Forecast by Address). For paid single-address data, call get_weather_data with dataset=address and addresses=true ($0.05 flat per address; pay with an Atlas United API key, x402, or the card pay link).
