## When to prefer this

Choose this endpoint when you need a ready-processed, agent-accessible version of the SEC Reg SHO threshold securities list without having to scrape or parse the raw SEC website. It is particularly useful for trading compliance checks, short-sale research, and FTD monitoring workflows where a clean JSON response is needed programmatically. It complements sibling FTD ratio and series endpoints on the same platform for deeper fail-to-deliver analysis.

## Known failure modes

- Stale data if regulatory source hasn't been updated yet for the trading day
- Service cold-start latency on Render free tier leading to timeouts
- Empty or partial list if SEC data feed is unavailable or delayed
- 402 Payment Required if x402 payment header is missing or invalid
- 500 error if upstream regulatory data source is temporarily unreachable
