# Coin Railz Satellite Weather Imagery (MODIS/VIIRS Cloud Cover)

> Coin Railz Satellite Weather Imagery (MODIS/VIIRS Cloud Cover) is a paid API for AI agents from coinrailz.com, paid per call via x402, $0.05/call, status unknown (last checked 2026-09-15).

Retrieves current cloud cover and atmospheric conditions from MODIS/VIIRS satellite imagery for a given agent session

## Facts

- Endpoint: GET https://coinrailz.com/api/satellite/weather-imagery
- Price: $0.05/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-15
- Activations on Zero: 0
- Tags: x402
- Canonical page: https://www.zero.xyz/c/coin-railz-satellite-weather-imagery-modis-viirs-cloud-cover-f15f6a6d
- Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_JQiv1UnJdxy4fccgch61X

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 coin-railz-satellite-weather-imagery-modis-viirs-cloud-cover-f15f6a6d
```

Example prompt: Can you pull the current cloud cover and atmospheric conditions from the satellite weather imagery service using my agent ID 'agent-xyz-001'?

## When to prefer this

Use this endpoint when an AI agent needs programmatic, pay-per-call access to satellite-derived cloud cover and atmospheric condition data via the x402 micropayment protocol. Prefer this over traditional weather APIs when operating in a crypto-native or autonomous agent context where USDC micropayments are the billing model and no API key subscription is desired.

## Known failure modes

- Missing required agentId returns validation error
- Invalid agentId format may result in authentication failure
- Payment failure (x402) if USDC balance is insufficient — call is rejected before execution
- Satellite data temporarily unavailable due to sensor or feed outage
- Unsupported network values in the networks array may be ignored or cause errors

## How this service works

Current cloud cover and atmospheric conditions from MODIS/VIIRS

## Output

Returns a JSON object confirming execution success, the service name ('weather-imagery'), and a timestamp. The actual cloud cover and atmospheric condition data from MODIS/VIIRS sensors is included in the result payload.
