api-key string

NOWNodes API key passed in the api-key header.

Signs a transaction with a key held in the node's keystore and submits it to the network.

Not usable on this endpoint.

eth_sendTransaction signs with a key from the node's keystore. Our nodes hold no keys - eth_accounts returns [] - so every call fails with -32000 unknown account. Sign the transaction on your side and broadcast it with eth_sendRawTransaction.
