# tools/weather (open-meteo)

> tools/weather (open-meteo) is a paid API for AI agents from sigtap-outreach-api.sigtap.workers.dev, paid per call via x402, $0.001/call, status unknown (last checked 2026-09-13).

Returns current weather conditions plus hourly temperatures for the next 3 hours, powered by open-meteo

## Facts

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 tools-weather-open-meteo-6b2b79de
```

Example prompt: What's the current weather right now — temperature, humidity, wind speed, and a short description — plus how warm or cold it'll be over the next 3 hours?

## When to prefer this

Choose this endpoint when you need a lightweight, low-cost current-conditions snapshot plus a short 3-hour temperature outlook without needing multi-day forecasts, precipitation details, or UV index. It's ideal for quick enrichment tasks, real-time dashboards, or agent workflows that just need 'what's the weather right now and in the next few hours' at minimal cost ($0.001 USDC).

## Known failure modes

- Service unavailable if open-meteo upstream is down — returns error response
- No location parameter in the schema means the endpoint may use a fixed or default location — results may not reflect the user's intended location
- Payment required (HTTP 402) if x402 payment header is missing or USDC balance is insufficient
- Stale data if open-meteo cache hasn't refreshed — weather_code may lag real conditions by minutes

## How this service works

Paid micro-utilities for cold-email outreach agents: domain deliverability audits, cold-email grading, template generation, plus a tools toolbox (hashing, JWT decode, IDs, slugs, JSON, regex, crypto prices, domain age, weather). Paid via x402 (USDC on Base). One signature per call. No keys. FREE CHECK: GET /preview/<paid-path> (same URL with /preview/ prefix) returns a 200 demo sample - verify output shape before paying. PAID CALL: GET the url -> 402 challenge -> sign + retry with X-PAYMENT -> settled on-chain (USDC, Base). Ready-to-paste client: GET /llms.txt section "Pay in one call". Catalog+MCP twin: /llms.txt.

## Output

A JSON object with two sections: 'current' containing temperature_2m (°C), weather_code, weather_description (e.g. 'Partly cloudy'), wind_speed_10m (km/h), and relative_humidity_2m (%); and 'next_3h' — an array of hourly objects each with a timestamp and temperature_2m value for the upcoming 3 hours.
