The subject id stays in the body, so it never reaches a URL or an access log; a GET with equals or where on the subject field is refused (use this call). subjectId: a string or a safe integer; the server canonicalises it (trim, NFC, the ledger’s case rule) and refuses an invalid id with VALIDATION. collection narrows the read to one collection; since and until are date-time bounds on the entry time; limit is 1 to 1000 (default 100).\n\npersonal defaults to sealed: personal fields read “[PERSONAL]”, and the subject field shows the subject token. personal decrypted shows the personal fields in clear; it needs the ledger_reveal permission and every such read is logged as kv.ledger.reveal. The answer never holds the subjectId, a subjectRef or a subject token outside the entries. subjectState is live, or shredded (then entries is empty, shreds lists the shred ids and earlierGenerationsShredded counts the earlier key generations that were shredded). A SUBJECT_NOT_FOUND error has a fixed message that never names the subject. The read is safe to repeat: a lost connection is 503 UNAVAILABLE with retryable true. Timeout 60 seconds.\n\nNeeds kv:ledger:read and the ledger_read permission.

Section titled “Request Bodyrequired”object
Read only this collection of the ledger.
Only entries at or after this time.
Only entries before this time.
Entries per page, 1 to 1000. The default is 100.
The nextToken of the previous page.
Sealed (the default): personal fields read “[PERSONAL]” and the subject field shows the subject token. decrypted: personal fields in clear; needs the ledger_reveal permission and is logged as kv.ledger.reveal.
Example
{ "subjectId": "user-4417", "collection": "audit:a", "limit": 100}Responses
Section titled “Responses”One page of the subject’s entries.
One page of the entries of a data subject. It never holds the subjectId, a subjectRef or a subject token outside the entries.
object
Empty when subjectState is shredded.
One key with its metadata. A ledger entry adds ledger and has no version. On a ledger entry, personal fields read “[PERSONAL]” and personal names them, unless the caller revealed them (reveal=true with the ledger_reveal permission). Unless revealed, the subject field of a pseudonym ledger shows the subject token (or “[PERSONAL]”, listed in personal). A shredded personal field reads {“$shredded”: true}.
object
The stored JSON value (any JSON type), decrypted when it was stored as a secret. In a key list a secret value reads [ENCRYPTED].
True when the value was stored as a secret.
Single-key reads only.
Single-key reads only.
Epoch seconds when the key expires. Absent when the key does not expire.
Format 2 stores only. A ULID, new on every write. Absent on ledger entries.
Ledger metadata of an entry. Present only on ledger entries.
object
The ledger name.
A ULID, a hyphen and the two-digit shard.
The sequence number in the shard.
Server time, epoch milliseconds.
The hash of the previous entry in the same shard.
Who wrote the entry, set by the KV service from the authenticated caller (never from the body) and covered by the entry hash. platform: a Quant service (quant-ledger writes the shred entries); api: an API caller (an append through this API with a portal token records principal token:
object
Present when the ledger has a subjectField: what the subject field holds.
Ledger entries only: the personal fields that read “[PERSONAL]”. [“*”] when the whole value is hidden (the ledger definition could not be read).
False when the time budget ended first: send the request again with nextToken.
Present when more entries remain.
Present when subjectState is shredded: the shred ids (KV_ledgers_shreds_receipt).
The number of earlier key generations of this subject that were shredded.
