math-evaluate

# math-evaluate Safe math expression evaluation with variables, descriptive statistics (mean, median, mode, stddev, percentiles), and percentage calculations. ## Data Handling This skill sends expressions to an external API for evaluation. The service does not store or log input data beyond the immediate response. ## Endpoints ### Evaluate Expression ```bash curl -X POST https://math.agentutil.net/v1/evaluate \ -H "Content-Type: application/json" \ -d '{"expression": "2 * x + y", "variables": {"x": 20, "y": 2}}' ``` ### Statistics ```bash curl -X POST https://math.agentutil.net/v1/statistics \ -H "Content-Type: application/json" \ -d '{"values": [10, 20, 30, 40, 50]}' ``` Returns: count, sum, mean, median, mode, min, max, range, variance, stddev. ### Percentage ```bash curl -X POST https://math.agentutil.net/v1/percentage \ -H "Content-Type: application/json" \ -d '{"operation": "change", "a": 100, "b": 125}' ``` Operations: `of` (a% of b), `change` (% change from a to b), `is_what_percent` (a is what % of b). ## Response Format ```json { "result": 42, "expression": "2 * x + y", "variables_used": {"x": 20, "y": 2}, "request_id": "abc-123", "service": "https://math.agentutil.net" } ``` ## Pricing - Free tier: 10 queries/day, no authentication required - Paid tier: $0.001/query via x402 protocol (USDC on Base) ## Privacy No authentication required for free tier.
