Measured tools (7)

• discover_capabilities

  List supported manufacturing processes, materials, and the fields an estimate accepts.

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• request_quote

  Get an instant cost estimate for a custom manufactured part. Returns unit price, total, lead time, and assumptions. Indicative and non-binding.

  Parameters:

  • process (required) — string
  • quantity (required) — integer
  • notes
  • finish
  • material
  • tolerance_mm
  • cad_reference
  • bounding_box_mm

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• refine_quote

  Refine a previous estimate (change quantity, material, tolerance, finish) by passing its quote_token.

  Parameters:

  • token (required) — string
  • process (required) — string
  • quantity (required) — integer
  • notes
  • finish
  • material
  • tolerance_mm
  • cad_reference
  • bounding_box_mm

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• get_lead_time

  Estimated production lead time in days, by process and quantity.

  Parameters:

  • process (required) — string
  • quantity (required) — integer

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• dfm_feedback

  Rule-based design-for-manufacturability feedback for a part specification.

  Parameters:

  • process (required) — string
  • quantity (required) — integer
  • notes
  • finish
  • material
  • tolerance_mm
  • cad_reference
  • bounding_box_mm

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• estimate_bom

  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.

  Parameters:

  • parts (required) — array

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared

• compare_processes

  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.

  Parameters:

  • processes (required) — array
  • quantity (required) — integer
  • finish
  • material
  • tolerance_mm
  • bounding_box_mm

  Hints: read-only not declared · destructive not declared · idempotent not declared · open-world not declared
