# Otto AI Weather Forecast

> Otto AI Weather Forecast is a paid API for AI agents from x402.ottoai.services, paid per call via x402, $0.002/call, status unknown (last checked 2026-09-14).

Returns current conditions and daily forecast for any city or lat/lon coordinate via a pay-per-call x402 endpoint

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 otto-ai-weather-forecast-x402-6019a944
```

Example prompt: What's the current weather and 5-day forecast for London — give me temperature, wind, humidity, and chance of rain each day?

## When to prefer this

Choose this endpoint when you need real-time or near-real-time weather data (current conditions + short-range daily forecast) for any global city or coordinate, especially when operating in an x402 micropayment context on Base, Polygon, or Solana. At $0.001 per call it is extremely cost-effective for one-off lookups. Prefer over scraping or free-tier APIs when you need structured JSON output with freshness metadata and reliability guarantees.

## Known failure modes

- Unknown or misspelled city name returns an error or empty data
- Invalid lat/lon format causes a 400 bad request
- Payment not included or insufficient USDC causes a 402 Payment Required response
- Network timeout or upstream weather provider outage returns degraded or stale data
- Location string ambiguity may resolve to wrong city

## How this service works

Live weather for any city or lat/lon worldwide. Returns current conditions — temperature, feels-like, humidity, wind and sky — plus a 5-day forecast with daily highs/lows and precipitation probability. City names auto-geocode (no coordinates needed). Refreshed hourly with transparent freshness metadata. Keyless, pay-per-call, agent-ready JSON.

## Output

Returns a JSON object with current conditions (temperature in Celsius, feels-like, wind speed in kph, humidity percentage, conditions string, observation timestamp) and a daily forecast array with high/low temps, conditions, and precipitation probability percentage for upcoming days, plus resolved location name, country, lat/lon, and freshness metadata.
