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 el-ni-o-market-watch-enso-indices-bundle-6a7fdcfa
```

Example prompt: Pull the latest ENSO index bundle for me — I need the current Niño 3.4 SST anomaly, Troup SOI, and IOD/DMI readings with their source links so I can assess whether El Niño or La Niña conditions are active right now.

## When to prefer this

Choose this endpoint when you need a single, pre-aggregated, multi-index ENSO bundle combining NOAA CPC SST anomalies, RONI, BOM Troup SOI, and IOD/DMI in one call with source attribution — ideal for commodity trading workflows, climate research, or automated monitoring agents that need weekly ENSO state without scraping multiple upstream agencies.

## Known failure modes

- Upstream NOAA CPC or BOM data unavailable — stale or missing index values
- Payment not completed — x402 payment required before data is returned
- Service timeout on Vercel serverless cold start
- Returned data may lag by up to one week if upstream sources haven't updated

## How this service works

Latest ENSO index bundle from El Niño Market Watch: weekly Niño 1+2/3/3.4/4 SST anomalies (NOAA CPC), RONI, Troup SOI (BOM) and weekly IOD/DMI — recent tails with exact source URLs.

## Output

A JSON object containing the most recent weekly tails of Niño 1+2, Niño 3, Niño 3.4, and Niño 4 sea surface temperature anomalies, the RONI, the Troup Southern Oscillation Index (BOM), the Indian Ocean Dipole Mode Index, a generation timestamp, and exact source URLs for each dataset.
