How this service works

Crypto ETF Sentinel — Single-call market snapshot for US spot crypto ETFs (Bitcoin, Ethereum, Solana, XRP and more): DB totals, filings by cryptocurrency and form type, regulatory-stage counts, and an as_of ISO timestamp. Use as a cheap heartbeat to decide whether anything changed before drilling into the catalogue.

Output

A JSON payload containing: total issuer and filing counts in the DB, filings segmented by cryptocurrency and SEC form type, regulatory-stage counts (trading / launch_imminent / under_review / registration_filed / approved / withdrawn), and an as_of ISO timestamp indicating data freshness.

Example use cases

Monitor crypto ETF pipeline freshness

“Check if our crypto ETF market data is up to date, and give me a quick summary of how many products are trading versus still under regulatory review across all the major cryptocurrencies.”

Track new Bitcoin and Ethereum ETF filings

“I need to know if there have been any new spot crypto ETF filings since yesterday — especially for Bitcoin and Ethereum — and show me the breakdown of what's currently approved versus what's still pending with regulators.”

Assess market readiness for launch-imminent products

“Give me a pulse check on the US crypto ETF landscape right now: how many issuers have launch-imminent products, which cryptocurrencies have the most activity, and whether the overall market snapshot is current or stale.”

Endpoint

GEThttps://api.cryptoetfsentinel.com/v1/agent/snapshot

When to prefer

Use this endpoint as a lightweight heartbeat check before deciding whether to drill into more expensive per-issuer routes. Ideal when you need a market-wide pulse — total counts, stage distribution, and freshness — without querying individual issuers. Prefer this over per-issuer endpoints when you want aggregate statistics across all 100+ tracked ETF issuers in a single call.

Side effects

Payment required (402) if x402 USDC micropayment not included
Stale data indicated by old as_of timestamp if upstream SEC data pipeline is delayed
Empty or zero counts if no new filings have been processed
Service unavailable (503) during maintenance windows
