Example prompt: Which US spot crypto ETF applications are currently stalled at the SEC with no comment-letter activity, and which ones are most at risk of being withdrawn?

## When to prefer this

Use this endpoint when you need a pre-filtered, ranked watchlist of at-risk crypto ETF applications — specifically those under SEC review with prolonged inactivity (148+ days) that historically correlates with withdrawal. Prefer this over generic SEC filing feeds when you want regulatory risk signals without building your own stall-detection logic.

## Known failure modes

- No stalled issuers found if all under-review issuers have recent activity (empty list response)
- 402 Payment Required if the x402 payment of 0.1 USDC is not provided
- Service unavailable if SEC data pipeline is delayed or down
- Stale data if SEC EDGAR scraping has not refreshed recently

## How this service works

Crypto ETF Sentinel — Under-review US spot crypto ETF issuers stalled 148+ days without comment-letter activity (a proxy for SEC inactivity), sorted by days since last activity. Long stalls historically correlate with withdrawal risk. Use when screening pending crypto ETF filings for abandonment or withdrawal risk.

## Output

A ranked list of under-review US spot crypto ETF issuers that have been inactive (no SEC comment-letter exchange) for 148 or more days, sorted by days-since-last-activity in descending order. Each entry likely includes issuer name, SEC CIK, number of stall days, and regulatory stage context indicating withdrawal risk.
