Plans for trial, live use, and enterprise rollout.

Start with live API access and a public benchmark. Move up when you need longer horizons, more users, higher limits, or support for production cutover.

Trial

Use it to check the API surface, next-day fit, and whether Gramm is worth a deeper side-by-side test.

Move up when Move up when a team needs shared access, longer horizons, or higher limits.

Standard

Best for a desk or operating team comparing 48-hour and 7-day runs against the feed they use today.

Move up when Move up when the forecast starts touching live decisions or 15-day coverage matters.

Pro

Built for live trading, dispatch, and planning workflows that need 15-day coverage, higher limits, and tighter support.

Move up when Move up when rollout adds procurement review, contract terms, or larger-team support.

Enterprise

For larger rollouts that need procurement review, a named owner, security review support, and commercial terms.

Move up when Use this when the main constraint is rollout discipline, not API volume.
