How this service works
Crypto ETF Sentinel — Chronological profile evolution for one US spot crypto ETF issuer: custodian, fee, AP-count and in-kind deltas across successive POS AM filings. Use when tracing how a fund's terms changed over time (fee cuts, custodian switches). Pass the issuer's SEC CIK as cik; optional limit.
Output
A chronological list of profile snapshots derived from successive POS AM SEC filings for the specified issuer, with each entry showing the delta or state of key fields: custodian, expense ratio/fee, authorized participants (APs), and in-kind redemption status, along with the filing date or sequence.
Example use cases
Example prompt
“Pull the full POS AM profile history for the spot Bitcoin ETF issuer with SEC CIK 0001980994 — I want to see how their custodian, fees, and authorized participants have changed over time across all their amendments.”
Technical details
Endpoint
GEThttps://api.cryptoetfsentinel.com/v1/profiles/historyWhen to prefer
Use this endpoint when you need the longitudinal regulatory profile of a single US spot crypto ETF issuer — specifically to audit changes in custodian arrangements, fee structures, authorized participant rosters, or in-kind mechanics across successive POS AM SEC filings. Prefer this over the bulk profiles endpoint when you want time-series delta analysis for one issuer rather than a current snapshot across all issuers.
Side effects
- Invalid or non-existent CIK returns an error (CIK must be a numeric string up to 10 digits)
- CIK belongs to an issuer with no POS AM filings returns empty history
- CIK exists in SEC system but is not a US spot crypto ETF issuer — may return empty or irrelevant results
- Payment not settled (x402 protocol) results in 402 Payment Required response
- Issuer has only one POS AM filing — no deltas computable, returns single-entry history
