# Pricing and field slots

> Compare the free Sandbox with the $49 Founder Pilot and understand exactly how field-slot usage is counted.

Human-readable version: https://agsemble.com/docs/pricing

## Two plans

- Sandbox — $0, no card, no expiry, 5 field slots, data export, Expo starter, and SDK; intended for evaluation and internal prototypes
- Founder Pilot — $49 USD per month, 100 field slots, six-hour weather freshness, weekly satellite monitoring when suitable imagery is available, durable history, export, and email support
- Neither plan has automatic overages. A limit returns a structured error instead of creating a surprise charge

> **Checkout mode:** Stripe-hosted Checkout is available in test mode so founders can validate the upgrade flow with a Stripe test card. Test mode creates no real charge or paid service. Live charging remains disabled until provider commercial terms, operator details, and final policies are approved. The Founder Pilot does not include an SLA.

## How field slots are counted

- One connected Polygon up to 25 hectares uses one field slot
- Each additional 25 hectares, rounded up, uses another slot
- Each disconnected MultiPolygon component is calculated separately and uses at least one slot
- Editing a field recalculates its slot use; seeded Sandbox fixture fields consume zero slots
- The mapper previews projected use before save, and the API rejects a save that would exceed the plan

## Technical fair use

Field slots are the front-facing plan meter. Monthly API and write limits remain as technical guardrails so a bug cannot create uncontrolled upstream cost.
