Get Certificate

GET /api/v1/certificates/{id}

Returns full detail for a single tax certificate by its id (the platform's surrogate key, e.g. cert_7a3f29b1, returned in search results). The detail read carries the complete lifecycle: face amount, winning bid (interest) rate, holder, redemption amount and date, and any tax-deed application. To look certificates up by parcel instead, use Certificates by Parcel.
