Foundry Weather Activity Window
x402
Foundry Weather Activity Window is a paid API for AI agents from foundry-par007-machine-revenue-mainnet.inference-chip-index.workers.dev, paid per call via x402, $0.01/call, status unknown (last checked 2026-09-14).
Returns NOAA forecast periods and contiguous time windows where all specified weather thresholds (wind, temperature, precipitation probability) are simultaneously satisfied for a given location.

How this service works
Pay-per-request evidence and data tools: CSV validation and reconciliation, DNS/email configuration evidence, and bounded official weather, earthquake, vehicle, company and study records. Exact USDC prices, explicit JSON contracts and source provenance. No mailbox, ownership, medical or safety guarantees.
Output
A JSON object containing: matched forecast periods with hourly conditions, contiguous time windows where ALL specified thresholds are simultaneously met, the requested window start/end, threshold values used, source provenance (NOAA URL, retrieval timestamp, attribution), and a coverage_complete flag indicating whether all hours in the window had forecast data.
Example use cases
Outdoor event scheduling check
“I'm planning an outdoor wedding ceremony near Austin, TX (lat 30.27, lon -97.74) this Saturday — can you find any 4-hour windows in the next 48 hours where wind stays under 20 kph, temperature is between 18°C and 32°C, and rain chance stays below 25%?”
Drone flight window planning
“I need to fly a drone for a survey near lat 37.8, lon -122.4 starting tomorrow — find windows in the next 24 hours where wind is under 15 kph, temperature is above 5°C, and precipitation probability is under 20%.”
Agricultural field spraying eligibility
“We're doing crop spraying near lat 41.5, lon -93.6 and need to know which 6-hour blocks in the next 48 hours have wind below 18 kph, temperatures between 8°C and 30°C, and less than 10% chance of rain.”
Technical details
Endpoint
POSThttps://foundry-par007-machine-revenue-mainnet.inference-chip-index.workers.dev/v2/official/weather-activity-windowWhen to prefer
Choose this endpoint when you need official NOAA-sourced forecast evidence filtered by multiple simultaneous weather thresholds for a specific US location — particularly when you need contiguous windows rather than just raw hourly data. Prefer this over general weather APIs when you need explicit source provenance, JSON-contract guarantees, and pay-per-request USDC pricing with no subscription. Not suitable for non-US locations, real-time lightning/gust/alert assessment, or safety-critical decisions.
Side effects
- Location outside NOAA coverage (non-US coordinates) returns empty periods and coverage_complete: false
- No windows found if thresholds are too strict — periods array may be populated but windows array empty
- Stale or unavailable upstream NOAA data may result in partial coverage with cache_age_seconds indicated
- Invalid latitude/longitude outside allowed ranges returns a validation error
- duration_hours or start_hours_from_now exceeding allowed maximums returns a schema validation error
