      tags:
      - Deprecated
      description: 'Returns *inaccurate* volume and base APY data for `main` registry pools on chains that aren’t indexed by either the [Curve Prices API](https://prices.curve.finance/feeds-docs) or the [Curve subgraphs](https://github.com/curvefi/volume-subgraphs).

        Data returned by this endpoint is necessarily inaccurate due to the manual chain-walking involved, coupled with the limitations of RPC endpoints available for this subset of chains. Using this endpoint should be considered an imperfect last resort.

        If the chain for which you want to retrieve volume and base APY data is available through either [`/getVolumes/{blockchainId}`](#/default/get_getVolumes__blockchainId_) or [`getSubgraphData/[blockchainId]`](#/default/get_getSubgraphData__blockchainId_), please use these.


        Note: At the moment, all chains with a `main` registry have support in one of the endpoints mentioned above. This endpoint will not return data for any chain anymore.
