# Amplifi Staking API Endpoint

> Record Amplifi staking positions for a specific datanet on the Reppo platform after submitting and confirming the on-chain staking transaction on Base.

Amplifi staking is a mechanism that lets token holders direct additional yield to a specific datanet by staking REPPO alongside it. This differs from curation staking (veREPPO locking): curation staking locks REPPO to earn voting power across the protocol, while Amplifi staking targets a single datanet to amplify its reward pool and signal support for that datanet's ecosystem.

After submitting the Amplifi stake transaction on Base, call this endpoint to record the position in the Reppo platform database.

  Internal ID of the datanet you are staking into.
</ParamField>

<ParamField body="txHash" type="string" required>
