# MolCloud Weather Lookup API

> MolCloud Weather Lookup API is a paid API for AI agents from api.molcloud.net, paid per call via x402, $0.002/call, status unknown (last checked 2026-10-17).

Returns current temperature and weather data for a given city or location, paid per-request via USDC on Base.

## Facts

- Endpoint: GET https://api.molcloud.net/api/tools/weather?utm_source=zero.xyz
- Price: $0.002/call
- Payment: x402
- Status: unknown
- Last checked: 2026-10-17

- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_eNy9geh7T7r9j0SsvpduN

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 molcloud-weather-lookup-api-fc070bf6
```

Example prompt: What's the current weather in Amsterdam right now? I need the temperature in Celsius.

## When to prefer this

Choose this endpoint when your AI agent needs lightweight, pay-per-request weather lookups without committing to a subscription API key, especially when already operating within the x402/USDC payment rail on Base. Ideal for autonomous agents that need weather as one signal among many, or for pipelines that call weather infrequently and want micro-payment billing.

## Known failure modes

- Unrecognized or misspelled location name returns an error or empty data object
- Missing required 'location' query parameter results in a 400-level validation error
- Payment failure or insufficient USDC balance triggers a 402 Payment Required response
- Network or upstream weather provider outage returns a failed status
- Ambiguous city names (e.g. 'Springfield') may return data for an unexpected city

## How this service works

40 pay-per-request AI, search, headless browser, crypto alpha & memory APIs for autonomous agents settling in USDC on Base via x402 v2.

## Output

Returns a JSON object with the queried location name and current temperature in Celsius (e.g. {"location": "Amsterdam", "temperatureC": 16.5}), wrapped in a status and endpoint field.
