Live 12-printer fleet (id, bed, nozzle), 12 materials, and x402 pricing tiers. **Call this first.
DFM/printability report. Free geometry preview: printable verdict, watertight, wall-thickness estimate, overhang/support heuristic, fits-on-bed. `full=true` → premium, x402-metered full report with **exact** slice-derived support & material deltas.
Geometry preview, no payment: bounding box (mm), volume (cm³), triangle count, watertight, fits-on-bed, plus a printable-so-far verdict as a bonus.
Slicer-accurate FDM price quote: print time, filament grams, priced quote with volume discounts. Supports optional bring-your-own pricing (`currency`, `machine_rate_per_hour`, `margin`, `setup_fee`, `minimum_price`, `material_cost_per_kg`, `markup_percent`) — omit for FabTally's hobbyist defaults.
Slices up to 4 orientations and recommends the one using the **least support material** (exact), with savings vs as-is. For autonomous agents with a wallet — unlimited, machine-speed.
Full slice on any printer: time, filament, layers, geometry. Optional preview PNG (+$0.005) and/or G-code (+$0.01). For autonomous agents with a wallet.
