Foundry Location Weather Evidence
x402
Foundry Location Weather Evidence is a paid API for AI agents from foundry-par007-machine-revenue-mainnet.inference-chip-index.workers.dev, paid per call via x402, $0.015/call, status unknown (last checked 2026-09-14).
Returns NOAA/NWS official forecast periods and active weather alerts for a given latitude/longitude, with full source provenance, freshness metadata, and USDC micropayment pricing.

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: normalized NWS forecast periods (name, startTime, endTime, temperature, temperatureUnit, windSpeed, windDirection, shortForecast, isDaytime), active weather alerts for the point, location echo (lat/lon), provenance block (license, attribution, terms URL, upstream call count, limitations), freshness metadata (retrievedAt, cacheAgeSeconds, state), and the upstream NWS source URL.
Example use cases
Field agent location weather check
“Get me the official NWS weather forecast for the next 6 periods at latitude 40.7128, longitude -74.0060, and flag any active weather alerts — I need the source provenance included.”
Automated logistics route weather evidence
“Fetch official weather evidence for coordinates 34.0522 latitude, -118.2437 longitude with up to 10 alert results and 8 forecast periods, so I can document conditions along our delivery route today.”
AI pipeline weather data enrichment
“Pull the NOAA forecast for lat 47.6062, lon -122.3321 — give me 3 forecast periods and any active alerts, I need the freshness timestamps and upstream source URL for our audit trail.”
Technical details
Endpoint
POSThttps://foundry-par007-machine-revenue-mainnet.inference-chip-index.workers.dev/v2/official/location-weather-evidenceWhen to prefer
Choose this endpoint when you need official, source-attributed US weather forecasts and active alerts with explicit provenance metadata, freshness timestamps, and a fixed per-call USDC micropayment price. Prefer it over generic weather APIs when auditability, source licensing, and machine-readable provenance are required — for example in AI pipelines, compliance workflows, or evidence-gathering agents. Not suitable for non-US locations, emergency safety warnings, or high-frequency polling due to per-call cost.
Side effects
- Coordinates outside NWS coverage area (e.g. non-US locations) may return empty or error results
- NWS API upstream outage returns a degraded or error response
- Invalid latitude/longitude range (outside -90 to 90 or -180 to 180) rejected by input schema
- Empty alert list does not guarantee safety — explicitly noted in provenance limitations
- Cache may serve data up to 30 seconds old; freshness state field indicates if retrieval is live
- Payment failure (insufficient USDC) returns HTTP 402 before any weather data is retrieved
