Example prompt: Pull up the full Storm Station 247 rank record for weather instrument key 'KORD' — I want to see its state rank today, how many reports it's sent versus what was expected, how fast they arrived, its longest silence, and how its ranking has changed day by day.

## When to prefer this

Choose this endpoint when you need detailed reliability and performance metrics for a specific US weather instrument, including its state-level rank, historical daily rankings, and reporting timeliness. It is uniquely suited for evaluating or comparing the trustworthiness of individual weather stations across the 73,000+ instruments tracked by Storm Station 247 — use it over generic weather APIs when the quality or rank of the data source itself matters.

## Known failure modes

- Missing or invalid 'key' query parameter returns an error or empty result
- Unknown instrument key returns no data
- Service unavailable during maintenance returns a non-200 HTTP status
- Rate limiting or payment failure (x402) if USDC payment is not correctly attached
