How this service works
Chronological profile evolution for one issuer — custodian/fee/AP/in-kind deltas over time, derived from successive POS AM filings.
Output
An ordered list of profile snapshots for the issuer, each snapshot corresponding to a POS AM filing, showing the delta or current state of key structural fields: custodian, management fee, authorized participants (APs), and in-kind redemption eligibility — allowing comparison of how the issuer's ETF structure has evolved filing by filing.
Example use cases
Audit custodian changes for compliance risk
“I need to track every time this crypto ETF issuer switched custodians — pull their full amendment history and flag any gaps or transitions that happened between filings.”
Compare fee structure evolution across competitors
“Show me how the management fees have changed over time for this ETF issuer, from their first POS AM filing to today, so I can see if they've been competitive or raised rates.”
Monitor authorized participant roster shifts
“I'm tracking whether this crypto ETF issuer has been adding or dropping authorized participants — give me a timeline of all AP list changes from their SEC filings so I can see the pattern.”
Technical details
Endpoint
GEThttps://api.cryptoetfsentinel.com/v1/profiles/0001980994/historyWhen to prefer
Use this endpoint when you need to audit or track how a specific crypto ETF issuer has changed their fund structure over time via POS AM amendments — especially for due diligence on custodian switches, fee reductions, AP roster changes, or in-kind policy shifts. Prefer this over the bulk profiles endpoint when you need longitudinal/temporal detail for one issuer rather than a current snapshot across all issuers.
Side effects
- CIK not found or not a crypto ETF issuer — returns empty or 404
- Issuer has no POS AM filing history yet — returns empty array
- SEC EDGAR source temporarily unavailable — may return stale or error response
- Invalid CIK format — schema validation error
- Payment not processed (x402) — 402 Payment Required response
