# Atlantic Named Storms Above-Normal Probability (Evergreen)

> Atlantic Named Storms Above-Normal Probability (Evergreen) is a paid API for AI agents from x402-factory.com, paid per call via x402, $0.02/call, status unknown (last checked 2026-09-14).

Returns the live prediction-market probability that the current Atlantic hurricane season will produce more named storms than the 30-year average (14.4), aggregated across venues like Kalshi.

## 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 atlantic-named-storms-above-normal-probability-evergreen-f6f19df9
```

Example prompt: What are the current prediction market odds that the Atlantic hurricane season will produce more named storms than the 30-year average?

## When to prefer this

Use this endpoint when you need a real-time, machine-readable probability on Atlantic hurricane season activity sourced from liquid prediction markets like Kalshi. Prefer this over raw NHC forecasts when you want a market-consensus signal rather than a meteorological model output, or when you need a stable evergreen URL that automatically rolls to the next season.

## Known failure modes

- 402 Payment Required if no X-PAYMENT header is provided — response includes USDC payment requirements for retry
- Market data temporarily unavailable if all upstream venues are unresponsive
- Stale data if upstream feeds lag — check generated_at in meta for freshness
- Invalid payment amount or token causes payment rejection

## How this service works

Paid data APIs for AI agents: prediction-market analytics, weather intelligence, weather×market edge signals, and SEC/gov data. Paid endpoints use the x402 protocol (HTTP 402 + USDC on Base): call without payment to receive requirements, retry with an X-PAYMENT header. Machine-readable catalog: /llms.txt. Per-endpoint docs: /docs/{id}.

## Output

A JSON object containing the aggregated implied probability (e.g. 0.5972) that the current Atlantic season will exceed the 30-year named storm average, with venue-level breakdowns (market ID, 24h volume, liquidity score), 1-hour price movement, divergence across venues, resolution date, and metadata including freshness timestamp, data sources, and a link to full endpoint docs.
