# AgentToll Space Weather API

> AgentToll Space Weather API is a paid API for AI agents from agenttoll.dev, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-15).

Retrieves current and historical space weather data including solar activity, geomagnetic storms, and related environmental metrics

## Facts

- Endpoint: POST https://agenttoll.dev/paid/env/space-weather
- Price: $0.02/call
- Payment: x402
- Status: unknown
- Last checked: 2026-09-15

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 agenttoll-space-weather-api-d9460aa4 -d '<json body>'
```

Example prompt: Pull space weather data for the last 7 days, including geomagnetic storm events, so I can assess conditions for our satellite operations.

## When to prefer this

Choose this endpoint when an AI agent needs structured, pay-per-call space weather data without committing to a subscription. Ideal for agents performing satellite operations planning, aurora prediction, radiation risk assessment, or scientific research that only occasionally needs space weather data. At $0.02 per call via x402/USDC on Base, it suits low-frequency or on-demand lookups.

## Known failure modes

- Invalid days integer causes 400 error
- Unknown or unsupported type string returns empty data or error
- Payment failure (insufficient USDC) blocks access
- Upstream space weather data source unavailable causes 503
- days value too large may be rejected or return partial data

## How this service works

108+ receipt-backed x402 work products for AI agents. Clear prices, spend caps, buyer metadata, and structured results over Base USDC.

## Output

Returns a structured response containing an array or object of space weather data records, along with metadata including the count of records, the data source, and the timestamp of generation. Also includes a boolean indicating whether the result was served from cache and a success flag.
