Polygon Area, Perimeter & Centroid Calculator

Use this endpoint when you need all three core polygon metrics — area, perimeter, and centroid — computed in a single call from an ordered vertex list. Prefer it over manual computation when dealing with arbitrary irregular polygons (not rectangles or triangles, which have sibling endpoints). Ideal when vertices are already in coordinate form and you need a fast, reliable geometric result without setting up a local math library.

• Fewer than 3 vertices provided — returns validation error
• Malformed coordinate pairs (not exactly 2 numbers) — schema validation failure
• More than 10,000 vertices submitted — exceeds maxItems limit
• Self-intersecting polygon passed — result may be geometrically incorrect without an error
• Non-numeric coordinate values — type validation error
• Payment not provided or insufficient — 402 Payment Required response
