# Saylor Innovations Data Desk – NOAA Climate Teleconnection Indices

> Saylor Innovations Data Desk – NOAA Climate Teleconnection Indices is a paid API for AI agents from saylorinnovations.com, paid per call via x402, $0.01/call, status unknown (last checked 2026-10-18).

Returns the latest monthly value, current phase (positive/negative/neutral), months in phase, and weather meaning for NOAA climate teleconnection indices NAO, AO, or PNA

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 saylor-innovations-data-desk-noaa-climate-teleconnection-indices-aa58000c
```

Example prompt: What's the current NAO index value, is it in a positive or negative phase, how long has it been in that phase, and what does that typically mean for weather? Show me the last 12 months of history too.

## When to prefer this

Choose this endpoint when you need authoritative NOAA-sourced teleconnection index data (NAO, AO, or PNA) with human-readable phase interpretation and weather meaning built in — saving you from parsing raw NOAA data files yourself. Prefer it over generic weather APIs when the user's question is specifically about large-scale climate oscillations and their weather implications rather than local forecasts or current conditions.

## Known failure modes

- Invalid index value (not nao/ao/pna) returns an error
- months parameter outside 1-120 range may be rejected or clamped
- NOAA data source temporarily unavailable may cause stale or missing results
- Network timeout if NOAA upstream is slow
- Missing or malformed query parameters may return a default (NAO, 12 months) rather than an error

## How this service works

NOAA climate teleconnection indices NAO, AO and PNA - latest monthly value, positive or negative phase, months in phase and what the phase means for weather

## Output

Returns a JSON object with the index name, latest numeric value, current phase label (positive/negative/neutral), the start month of the current phase (YYYY-MM), number of months in that phase, a plain-language description of what the phase means for weather, a note or caveat, the NOAA data source, and an array of historical monthly values in time order.
