How this service works
Crypto ETF Sentinel — Week-over-week pipeline delta for US spot crypto ETFs: change in stage counts, filings-7d and under-review count vs a prior daily snapshot (days_back, default 7, max 90). Use when you want the net movement of the crypto ETF pipeline since your last check rather than a full snapshot. Returns 404 (no charge) when no snapshot exists.
Output
A JSON object containing week-over-week pipeline delta metrics: changes in count per regulatory stage (e.g. registration_filed, under_review, launch_imminent, trading), number of new filings in the last 7 days, and delta in under-review count relative to the prior daily snapshot. Returns 404 (no charge) if no snapshot exists for the requested days_back value.
Example use cases
Example prompt
“Pull the Crypto ETF Sentinel pipeline deltas for 7 days back and tell me how the US spot crypto ETF approval stages have shifted — specifically how many more or fewer filings and under-review ETFs there are compared to that snapshot.”
Technical details
Endpoint
GEThttps://api.cryptoetfsentinel.com/v1/pipeline/deltasWhen to prefer
Use this endpoint when you need to understand directional changes in the US spot crypto ETF regulatory pipeline over time — specifically how stage counts and filing activity have shifted relative to a prior snapshot. Prefer this over static directory endpoints when the goal is trend detection or monitoring rather than point-in-time lookup.
Side effects
- 404 returned when no snapshot exists for the requested days_back value (no charge applied)
- Invalid days_back parameter may result in a 400 or empty response
- Service unavailable if underlying SEC data pipeline has not refreshed
