```

Example prompt: Can you pull the latest IPO registration withdrawals from SEC Form RW filings — I want to see which companies pulled their S-1 or F-1 and how long they were in registration before withdrawing?

## When to prefer this

Use this endpoint when you need to track IPO market risk sentiment via withdrawn registration filings, want to identify companies that abandoned their public offering attempts, or need to analyze how long issuers stayed in registration before pulling out. Prefer this over general IPO calendar endpoints when the focus is on failed/withdrawn offerings rather than upcoming or priced deals.

## Known failure modes

- No data returned if no recent withdrawals are on file
- Payment not completed results in 402 error
- Malformed or missing required fields in response if SEC source data is incomplete
- Stale data if SEC EDGAR has not been recently crawled
