+1. Use the [Hermes](pythnet-price-feeds/hermes) endpoint `/v2/updates/price/{price_time}` to retrieve a signed price update for the desired price feed and time.
    This endpoint will return a signed price update, specifically the price update immediately after the queried time.
    This step can be done in either a web frontend or a backend process, depending on who is expected to initiate the transaction.
 2. Pass this price update to your on-chain contract as part of the transaction that needs the benchmark data.

    The price update will only be valid if the signatures are correct and the update falls within a user-configured time interval; integrators should set this time interval such that it matches their desired time.
 
 Note that this process is similar to the standard process for consuming pull updates.
-The main differences are that users call the `get_vaa` endpoint instead of `latest_vaas`, and the on-chain contract calls `parsePriceFeedUpdates` instead of `updatePriceFeeds`.

 The pyth-crosschain repo has [example code](https://github.com/pyth-network/pyth-crosschain/blob/main/target_chains/ethereum/sdk/js/src/examples/EvmBenchmark.ts) for an integration along the lines above for EVM chains.
