How this service works
Crypto ETF Sentinel — Top-N most-active pre-approval US spot crypto ETF issuers by 42-day action-filing count (S-1/A, CORRESP and similar). High velocity means sustained SEC dialogue, a frequent leading indicator of stage transitions. Use when you want to know which pending crypto ETFs are moving right now. Optional limit param.
Output
An ordered list of the top-N pre-approval US spot crypto ETF issuers ranked by their 42-day SEC action-filing count, including issuer name, CIK, filing count, velocity rank, and current regulatory stage — indicating which issuers are in sustained dialogue with the SEC and likely nearing a stage transition.
Example use cases
Example prompt
“Which US spot crypto ETF issuers are filing the most aggressively with the SEC right now — show me the top issuers ranked by their 42-day action-filing count so I can spot who's closest to approval.”
Technical details
Endpoint
GEThttps://api.cryptoetfsentinel.com/v1/pipeline/velocityWhen to prefer
Use this endpoint when you need a macro-level signal of which crypto ETF issuers are most active in their SEC approval process, especially to identify candidates likely to imminently transition stages. Prefer this over single-issuer comment letter or XBRL endpoints when you want a ranked comparative view across all pre-approval issuers rather than deep-dive data on one specific issuer.
Side effects
- No pre-approval issuers found if all active issuers have transitioned to trading/withdrawn — returns empty list
- Payment required (402) if x402 USDC payment header is missing or insufficient
- Invalid query parameters return 400 validation error
- Stale data if SEC EDGAR feed has not refreshed recently — filing counts may lag by hours
