No key of your own needed. The "Live peak data by WattMarkets" footer link stays on the free tier. White-label removal will be the first paid feature.

For consultants and brokers

Put the live call in your client reports and portals. The rules are short: keep the "Live peak data by WattMarkets" footer, don't re-sell the raw feed as your own, and the data stays free. The full ledger is exportable through the API if you'd rather build your own view. One consultant carries the call into twenty plants, which is exactly what we want.
