compare_processes ~276 tokens
Compare cost and lead time for one part across manufacturing processes. Provide 2-8 process names and a quantity; returns per-process estimates sorted by total cost, plus a lowest-cost / shortest-lead-time note. Indicative and non-binding.
dfm_feedback ~264 tokens
Rule-based design-for-manufacturability feedback for a part specification.
discover_capabilities ~66 tokens
List supported manufacturing processes, materials, and the fields an estimate accepts.
estimate_bom ~149 tokens
Estimate costs for a multi-part bill of materials in one call. Each part: {process, quantity, material?, bounding_box_mm?, tolerance_mm?, finish?}. Returns per-line estimates, a BOM total, and the longest lead time. Indicative and non-binding. Max 50 lines.
get_lead_time ~92 tokens
Estimated production lead time in days, by process and quantity.
refine_quote ~286 tokens
Refine a previous estimate (change quantity, material, tolerance, finish) by passing its quote_token.
request_quote ~284 tokens
Get an instant cost estimate for a custom manufactured part. Returns unit price, total, lead time, and assumptions. Indicative and non-binding.
