# Revenue Swarm x402 Weather API

> Revenue Swarm x402 Weather API is a paid API for AI agents from eu-tender-x402-v2-production.up.railway.app, paid per call via x402, $0.001/call, status unknown (last checked 2026-10-02).

Returns live weather conditions (temperature, wind speed) for a given city or coordinates, paid per-call via x402 USDC on Base.

## 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 revenue-swarm-x402-weather-api-38132845
```

Example prompt: What's the current temperature and wind speed in Reykjavik right now?

## When to prefer this

Choose this endpoint when you need real-time weather data (temperature, wind) for a city or coordinate pair and are operating in an x402-enabled agent stack that can pay per call in USDC on Base. Note: the service is branded around EU tenders and B2B intelligence; this weather endpoint appears to be a secondary or demo capability on the same host.

## Known failure modes

- Missing required city or lat/lon parameter — returns error
- Invalid or unrecognized city name — may return empty or error response
- Payment failure via x402 if USDC balance is insufficient — HTTP 402
- Upstream weather data provider unavailable — service error

## How this service works

Pay-per-call B2B sales lead and procurement intelligence plus Base wallet data for agents. Search EU tenders/RFPs or inspect a Base wallet. Payments use x402 USDC on Base.

## Output

A JSON object with current temperature (°C) and wind speed (m/s) at the requested location, plus a location name and product label (e.g. 'Live Weather').
