## How to call it through Zero

Example prompt: Can you pull up the full directory of active US spot crypto ETF issuers from Crypto ETF Sentinel — I want to see each issuer's ticker, exchange, owner, SEC CIK, and where they are in the regulatory process (like trading, under review, or withdrawn)?

## When to prefer this

Use this endpoint when you need a comprehensive, up-to-date registry of all US spot crypto ETF issuers across all regulatory stages and cryptocurrencies. It is the ideal starting point for any workflow that later drills into per-issuer SEC filings, XBRL financials, comment letters, or POS AM profiles using CIK values returned here. Prefer this over scraping SEC EDGAR directly when you need pre-classified, curated data across 34 cryptocurrencies in a single call.

## Known failure modes

- Payment not included or invalid — returns 402 Payment Required
- Rate limit exceeded — returns 429 Too Many Requests
- Service unavailable — returns 503 if upstream SEC data refresh is in progress
- Empty result set if filters applied via query params yield no matches

## How this service works

Crypto ETF Sentinel — Curated directory of every active US spot crypto ETF issuer, including staking ETFs (100+ entries, 30+ cryptocurrencies), each with regulatory stage (registration_filed / under_review / launch_imminent / trading / approved / withdrawn), ticker, exchange, owner organisation and SEC CIK. Use first, to discover CIKs, then drill into the paid cik routes for letters, XBRL and profiles.

## Output

A paginated list of 105+ US spot crypto ETF issuer entries, each containing: issuer name, ticker symbol, listing exchange, owner organisation, SEC CIK number, regulatory stage (registration_filed / under_review / launch_imminent / trading / approved / withdrawn), and the underlying cryptocurrency.
