# Data Oracle (V2 Roadmap)

> Bi-directional financial data oracle: not yet live in the API.

<Warning>
  This pillar is **not in the current API surface**. It's scoped as V2 work (ZK-TLS Financial Data Oracle), sequenced after the V1 identity + direct-debit modules, and mapped to the Stellar Attestation Verifier module rather than Aptos.
</Warning>

## Intended capability

**Web2 → Web3 (privacy-preserving inputs):** a Zero-Knowledge TLS oracle streams authenticated bank/account history on-chain without exposing the underlying transaction data. Only a cryptographic proof of financial health is published, e.g. to underwrite an undercollateralized loan.

**Web3 → Web2 (asset aggregation):** an indexer normalizes multi-chain wallet activity (DeFi yields, tokenized RWAs, staked balances) into a clean feed consumable by traditional risk/underwriting systems.

## Illustrative shape (subject to change)

```bash theme={null}
# Not yet implemented
curl https://api.openfi.co/v1/oracles/attestations \
  -H "Authorization: Bearer $OPENFI_API_KEY" \
  -d '{
    "account_id": "acc_123",
    "attestation_type": "bank_balance_proof"
  }'
```

Under evaluation for the underlying ZK/attestation tooling: **Reclaim Protocol** or **TLSNotary**.

See the [Treasury Auto-Rebalancing use case](/use-cases#2-treasury-auto-rebalancing) for where this fits in a full flow.
