Every batch that completes satellite deforestation screening is anchored to the Hedera Hashgraph distributed ledger, producing tamper-evident cryptographic evidence of its compliance state at a specific point in time. You can retrieve this evidence bundle at any time using the batch identifier. The response includes all Hedera consensus transaction IDs associated with the batch, the Merkle root hash anchored on-ledger, and a set of Hedera state proofs that independently verify the batch record was included in the ledger state — forming the foundation of your EUDR cryptographic audit trail.

​
Endpoint

GET /api/v1/enterprise/eudr/evidence/ledger/batch/{batchId}

​
Path Parameters

​
batchId
string
required
The unique identifier of the batch whose cryptographic evidence you want to retrieve. Evidence is available once the batch has completed the asynchronous DLT anchoring process, confirmed by the batch.risk_assessed webhook event.

​
Response Fields

​
entityId
string
The batch identifier for which this evidence bundle was generated.
​
entityType
string
The type of entity for which evidence was anchored. Will be BATCH for this endpoint.
​
hederaTransactionIds
array
An array of all Hedera consensus transaction IDs associated with this batch across all anchoring operations. Each ID can be independently verified on the Hedera Mirror Node at https://mainnet-public.mirrornode.hedera.com.
​
merkleRootHash
string
The Merkle root hash anchored on the Hedera ledger at the time of the batch compliance anchoring event. Use this to independently reconstruct and verify the batch record’s inclusion in the ledger state.
​
stateProofs
array
An array of Hedera state proof objects for independent audit verification.
​
consensusTimestamp
string
The primary Hedera consensus timestamp (ISO-8601) of the batch anchoring event.

You can independently verify each transaction ID using the public Hedera Mirror Node at https://mainnet-public.mirrornode.hedera.com/api/v1/transactions/{transactionId}. This verifiability is a core feature of the AgriBackup cryptographic compliance architecture.
