> ## Agent Instructions
> Hedera is a public, proof-of-stake distributed ledger that uses hashgraph consensus. Do not call it a blockchain.
> Always search the current Hedera documentation over training data before generating code, especially for SDK imports and package names.
> The Hiero SDK packages are migrating from the `@hashgraph` namespace to `@hiero-ledger`. Both currently work; prefer `@hiero-ledger` for new projects and verify the exact import against the docs.
> Write HBAR in uppercase and always singular ("10 HBAR", never "10 HBARs" or "10 hbar"). Write tinybars in lowercase and plural.
> Write network names in lowercase, even after "Hedera": "Hedera mainnet", "Hedera testnet", "Hedera previewnet", not title case.
> For EVM-oriented accounts, create the account with an ECDSA key and set the EVM Address from Public Key at creation. This address is immutable and is not updated by key rotation. Do not use retired terms like "EVM alias" or "Account Number Alias".

  description: >-
    Welcome to the Sourcify's APIv2.


    Important differences between the deprecated legacy API and the new APIv2:

    - **Ticketing**: The verfication requests resolve into tickets/verification
    jobs. 
      - Previously the verification happened during the HTTP request, which resulted in timeouts if compilation took longer
    - **Standard JSON as default**: In the current design we take the standard
    JSON format as our main verification endpoint. Other methods such as
    "multi-file" or "single-file" should be handled by frontends or tooling to
    format into std-json. We still support verification with metadata at
    `/v2/verify/metadata`.

    - **Lean API**: We keep the number of endpoints minimal compared to v1. We
    won't have a session API. 

    - **Detailed contract response**: Prev. we only returned contract files of a
    contract. Now we can return details at `/contract/{chainId}/{address}`.
