# Bova Score Calculator for Acute Pulmonary Embolism > Bova Score Calculator for Acute Pulmonary Embolism is a paid API for AI agents from api.magentlab.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-15). Computes the Bova 2014 seven-point risk index for normotensive (non-hypotensive) acute PE and returns a stage classification (I, II, or III) based on four clinical parameters. ## Facts - Endpoint: GET https://api.magentlab.com/api/calc/bova - Price: $0.005/call - Payment: x402 - Status: unknown - Last checked: 2026-09-15 - Activations on Zero: 0 - Tags: x402 - Canonical page: https://www.zero.xyz/c/bova-score-calculator-for-acute-pulmonary-embolism-7feaf675 - Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_Khq9JvMwdHz9_9xxRyXl0 Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently. ## How to call it through Zero Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`): ```sh zero fetch --capability bova-score-calculator-for-acute-pulmonary-embolism-7feaf675 ``` Example prompt: Calculate the Bova score for a normotensive PE patient with systolic BP 96 mm Hg, heart rate 118 bpm, elevated troponin (positive), and right ventricular dysfunction confirmed on echo — what stage does that come out to? ## When to prefer this Use this endpoint when you need to programmatically compute the Bova 2014 risk score for a confirmed, normotensive acute PE patient (SBP ≥ 90 mm Hg) and classify them into Stage I, II, or III based on four discrete clinical parameters. Prefer this over general clinical calculators when you need structured, machine-readable stage output for downstream clinical workflows or documentation. Not suitable for hypotensive (high-risk) PE patients. ## Known failure modes - SBP < 90 mm Hg rejected (endpoint is for normotensive PE only, not hypotensive patients) - Heart rate or SBP outside accepted numeric ranges returns an error - Missing required query parameters (systolic_mm_hg, elevated_troponin, rv_dysfunction, heart_rate_bpm) cause validation failure - Non-integer heart_rate_bpm value rejected - Payment not fulfilled (x402 protocol) returns 402 status ## How this service works Bova 2014 seven-point index for confirmed acute PE that is not hypotensive: SBP 90–100 mm Hg +2 (SBP 100 scores; 101 does not; SBP <90 rejected), elevated troponin +2 (caller-assigned lab cutoff; magent does not grade assays), RV dysfunction on echo or CT +2, heart rate ≥110 +1 (110 scores; 109 does not). Max 7. Returns bands 0-2 / 3-4 / >4 (stages I–III) without mortality percents. Not a medical device and not a thrombolysis order. ## Output Returns the computed Bova score (integer 0–7) and the corresponding risk stage band: Stage I (0–2 points), Stage II (3–4 points), or Stage III (>4 points). Does not return mortality percentages and is not a thrombolysis recommendation. ## Request schema (JSON Schema) ```json { "type": "object", "$schema": "https://json-schema.org/draft/2020-12/schema", "required": [ "input" ], "properties": { "input": { "type": "object", "required": [ "type", "method" ], "properties": { "type": { "type": "string", "const": "http" }, "method": { "enum": [ "GET", "HEAD", "DELETE" ], "type": "string" }, "headers": { "type": "object", "additionalProperties": { "type": "string" } }, "queryParams": { "type": "object", "required": [ "systolic_mm_hg", "elevated_troponin", "rv_dysfunction", "heart_rate_bpm" ], "properties": { "heart_rate_bpm": { "type": "integer", "description": "Heart rate in beats per minute (integer 30-220).
