## When to prefer this

Use this endpoint when you need real-time, undelayed SEC filing data for US spot crypto ETFs, especially for trading signals, compliance surveillance, or continuous polling workflows. It is preferable to the free /v1/filings route whenever freshness is critical, since the free route has a 24-hour data delay. Choose this when you need to filter by currency, filing type, or date range and require predictable per-call pricing.

## Known failure modes

- Invalid currency filter returns empty result set or 400 error
- Invalid filing_type value returns 400 or empty dataset
- date_after format mismatch causes 400 bad request
- Payment not received causes 402 Payment Required response
- Server error returns 500 with error field populated
- No filings matching filters returns empty data array with total: 0
