# P0 Weather Forecast by Coordinates > P0 Weather Forecast by Coordinates is a paid API for AI agents from x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-10). Returns hourly/6-hourly weather forecasts and active weather alerts for a given latitude/longitude, sourced from MET Norway and NWS ## Facts - Endpoint: GET https://x402-bazaar-rank.x402-bazaar-rank-worker.workers.dev/weather?utm_source=zero.xyz - Price: $0.001/call - Payment: x402 - Status: unknown - Last checked: 2026-10-10 - Activations on Zero: 0 - Tags: x402 - Canonical page: https://www.zero.xyz/c/p0-weather-forecast-by-coordinates-b6c8a059 - Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_gWYL1wFhflW42yW6eejdN Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently. ## How to call it through Zero Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`): ```sh zero fetch --capability p0-weather-forecast-by-coordinates-b6c8a059 ``` Example prompt: What's the weather forecast for the next 48 hours at latitude 40.71, longitude -74.01? Include temperature, wind, precipitation, and any active alerts. ## When to prefer this Choose this endpoint when you need structured, machine-readable hourly weather forecast data for any global latitude/longitude coordinate pair, especially in agentic pipelines that require precise field-level weather variables (temperature, wind, precipitation, humidity) rather than a human-readable summary. It is particularly useful when you also need U.S. weather alerts co-located with the forecast. Prefer it over general weather APIs when you want a clean, normalized JSON schema with clear units and attribution, and when you are operating in an x402 micropayment context. Not suitable for aviation, marine, or life-safety decisions. ## Known failure modes - Invalid lat/lon values outside -90/90 or -180/180 range return validation errors - Coordinates in regions not covered by MET Norway forecast may return empty or partial point arrays - NWS alert fetching may fail independently, indicated by alertsStatus field being non-'ok' - Payment failure (402) if USDC micropayment is not correctly submitted - Requesting more than 240 hours returns a validation error - Network timeouts from upstream MET Norway or NWS APIs may cause delayed or error responses ## How this service works An open index of the machine-to-machine (agent) economy. x402 routes: ranked discovery over the live x402 service market, every indexed service scored by real 30-day calls and paying-wallet bounds, with a receipt naming the snapshot hash and scoring revision. /economy routes, for Tempo MPP, Virtuals ACP, Olas, Masumi, ERC-8004 agent registries, Solana agent registries, Base agent contracts and MCP servers (Official MCP Registry): each protocol's published figures (agent or server counts, transactions or payment events; payers and USD volume only where the source publishes them: payers for x402 and Tempo MPP, USD volume for x402 and Virtuals ACP), each with its unit, window and source; units differ, so totals are not summed. L402 and per-service MPP listings are not covered. ## Output A JSON object containing an array of forecast time points (each with temperature in Celsius, wind speed in m/s, wind direction in degrees, precipitation in mm, humidity %, cloud cover %, and pressure in hPa), plus any active weather alerts from NWS, attribution details, the actual rounded coordinates used, and a generation timestamp. Units are clearly labeled and forecast data is attributed to MET Norway under CC BY 4.0. ## Request schema (JSON Schema) ```json { "type": "object", "$schema": "https://json-schema.org/draft/2020-12/schema", "required": [ "input" ], "properties": { "input": { "type": "object", "required": [ "type", "method" ], "properties": { "type": { "type": "string", "const": "http" }, "method": { "enum": [ "GET", "HEAD" ], "type": "string" }, "queryParams": { "type": "object", "required": [ "lat", "lon" ], "properties": { "lat": { "type": "number", "maximum": 90, "minimum": -90, "description": "latitude in decimal degrees" }, "lon": { "type": "number", "maximum": 180, "minimum": -180, "description": "longitude in decimal degrees" }, "hours": { "type": "integer", "default": 48, "maximum": 240, "minimum": 1, "description": "forecast horizon in hours (hourly steps first, then 6-hourly as MET publishes)" } } } }, "additionalProperties": false }, "output": { "type": "object", "required": [ "type" ], "properties": { "type": { "type": "string" }, "example": { "type": "object", "required": [ "lat", "lon", "hours", "points", "alertsStatus", "attribution", "note" ], "properties": { "lat": { "type": "number" }, "lon": { "type": "number" }, "note": { "type": "string" }, "hours": { "type": "integer" }, "units": { "type": "object" }, "alerts": { "type": [ "array", "null" ], "items": { "type": "object" } }, "points": { "type": "array", "items": { "type": "object", "required": [ "time" ], "properties": { "time": { "type": "string" }, "tempC": { "type": [ "number", "null" ] }, "symbol": { "type": [ "string", "null" ] }, "windMs": { "type": [ "number", "null" ] }, "cloudPct": { "type": [ "number", "null" ] }, "precipMm": { "type": [ "number", … (truncated) ``` ## Response schema (JSON Schema) ```json { "type": "json", "example": { "lat": 40.71, "lon": -74.01, "note": "Forecast, not an observation.
