Output
A structured object containing the latest POS AM-extracted profile for the requested issuer: custodian name, sponsor fee (expense ratio), list of authorized participants (APs), whether in-kind creation/redemption is eligible, and basket size — all sourced from SEC POS AM filings.

Technical details
Endpoint
GEThttps://api.cryptoetfsentinel.com/v1/profiles/issuerWhen to prefer
Use this endpoint when you need structured regulatory profile data (custodian, fee, APs, basket size, in-kind eligibility) for a specific US spot crypto ETF issuer identified by SEC CIK. Prefer this over the bulk profiles endpoint when querying a single issuer to minimize cost, and over the XBRL snapshot endpoint when you need POS AM prospectus-sourced structural details rather than financial metrics like AUM or NAV.
Side effects
- Invalid or non-numeric CIK returns a 400 validation error
- CIK not found in the Crypto ETF Sentinel database returns a 404
- CIK belongs to a non-crypto or non-spot ETF issuer — no profile available
- Payment not included or insufficient — 402 Payment Required
- POS AM filing not yet processed — partial or missing fields in response
- Rate limiting or service unavailability — 429 or 5xx errors
