Technical details
Endpoint
GEThttps://api.cryptoetfsentinel.com/v1/xbrl/issuers/0001980994/seriesWhen to prefer
Use this endpoint when you need a historical trend or time series for a specific XBRL financial concept (AUM, NAV, shares outstanding, expense ratio) on a single crypto ETF issuer, rather than just the latest snapshot. Prefer this over the single-issuer snapshot endpoint when temporal analysis, trend detection, or quarter-over-quarter comparison is the goal.
Side effects
- Issuer CIK not found – returns 404 if the CIK does not correspond to a tracked crypto ETF issuer
- XBRL concept not available for issuer – some issuers may not have filed certain concepts, returning empty series
- No historical data yet – newly listed ETFs may have only one or zero quarterly data points
- Payment not authorized – x402 payment required; missing or invalid payment header returns 402
- Rate limiting or quota exceeded – returns 429 if too many calls are made in a short period
