Example prompt: Pull the latest Crypto ETF Sentinel risk scores for all US spot crypto ETFs currently under SEC review — I want to see which issuers have the highest composite risk based on filing cadence, comment-letter intensity, and time-in-stage.

## When to prefer this

Use this endpoint when you need a quick, pre-computed composite regulatory risk signal across all active US spot crypto ETF applicants without having to manually analyze individual SEC filing histories. Prefer this over individual issuer comment-letter or XBRL endpoints when you want a broad risk overview rather than deep issuer-specific detail. Ideal for portfolio screening, regulatory monitoring dashboards, or comparative issuer analysis.

## Known failure modes

- No ETFs currently under SEC review — empty data array returned
- Payment not authorized — 402 Payment Required if x402 USDC payment not completed
- Invalid query parameters — 400 Bad Request with error description
- Service temporarily unavailable — 503 with retry guidance
- Stale data — scores may lag real-time SEC filings by a few hours

## How this service works

Crypto ETF Sentinel — Regulatory risk score (0-99) for every US spot crypto ETF (Bitcoin, Ethereum, Solana and more) under SEC review: a composite of filing cadence, time-in-stage, comment-letter intensity and historical approval baselines. Use when ranking or screening pending crypto ETF filings by regulatory risk. A heuristic benchmark, not a probability or prediction.

## Output

A list of per-issuer composite risk scores (0–99) for every US spot crypto ETF under SEC review, along with underlying score components such as filing cadence, time-in-stage, comment-letter intensity, and historical approval baseline comparisons.
