## 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 pjm-nowcast-regime-endpoint-b9ee9ac0 -d '<json body>'
```

Example prompt: What's the current PJM RTO market regime — pull the latest nowcast stats on LMP levels, zonal price spreads, and grid load so I can see where prices stand right now.

## When to prefer this

Choose this endpoint when you need a quick, low-cost ($0.02 USDC) characterization of the current PJM energy market regime — especially trailing LMP stats, zonal spreads, and load — without needing official PJM data products. Best for situational awareness, not trading decisions. Prefer official PJM APIs when you need authoritative, real-time, or legally compliant data.

## Known failure modes

- Stale data if background polling has not succeeded recently — figures may lag real-time conditions
- Service unavailability on the Railway.app hosting platform
- Empty or null fields if market data source is temporarily unavailable
- HTTP 402 if payment of $0.02 USDC is not provided or fails
- Unexpected schema if upstream PJM data format changes

## How this service works

Trailing and semi-live descriptive statistics on PJM RTO LMP, selected zonal LMP price spreads, and RTO load. Not a forecast, signal, trading recommendation, or advice. Not a substitute for official PJM data products. Buyer beware: figures are aggregated from public market sources; freshness equals the last successful background poll. Descriptive statistics only. Not a forecast, signal, or trading recommendation. Aggregated from public market sources. Freshness depends on the last successful background poll.

## Output

Returns descriptive statistics characterizing the current PJM RTO 'regime' — including trailing and semi-live summary stats on RTO-wide LMP, selected zonal LMP price spreads, and aggregate RTO load. Data freshness depends on the last successful background poll from public PJM market sources. Not a forecast, signal, or trading recommendation.
