# magent PLASMIC Score Calculator > magent PLASMIC Score Calculator is a paid API for AI agents from api.magentlab.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-14). Computes the Bendapudi 2017 PLASMIC score (0–7) for pretest stratification of severe ADAMTS13 deficiency in suspected TTP ## Facts - Endpoint: GET https://api.magentlab.com/api/calc/plasmic - Price: $0.005/call - Payment: x402 - Status: unknown - Last checked: 2026-09-14 - Activations on Zero: 0 - Tags: x402 - Canonical page: https://www.zero.xyz/c/magent-plasmic-score-calculator-8ece4e59 - Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_E8n6kcYoz3Xn4NlYc9s4W 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 magent-plasmic-score-calculator-8ece4e59 ``` Example prompt: Calculate the PLASMIC score for my patient: platelets 22 ×10^9/L, hemolysis present (reticulocyte count elevated), no active cancer, no transplant history, MCV 82 fL, INR 1.1, creatinine 1.4 mg/dL — what's the score and which pretest risk band does it fall in? ## When to prefer this Use this endpoint when you need a deterministic, rule-based PLASMIC score computation for Bendapudi 2017 TTP pretest stratification and do not want to rely on manual arithmetic. Prefer this over general LLM arithmetic when auditability and exact boundary handling (strict less-than cutoffs) are required. Not a replacement for ADAMTS13 assay results or clinical judgment. ## Known failure modes - Missing required query parameters (platelets, hemolysis, active_cancer, solid_organ_or_stem_cell_transplant, mcv_fl, inr) returns a 400 error - Values outside accepted ranges (e.g. platelets >2000 or MCV <50) may return validation errors - Neither creatinine_mg_dl nor creatinine_umol_l provided results in missing-field error - Payment not included or insufficient returns 402 Payment Required - Boundary values (platelets=30, MCV=90, INR=1.5, creatinine=2.0) correctly score 0 — do not treat as errors ## How this service works Bendapudi 2017 PLASMIC: seven 1-point items (platelets <30×10^9/L, caller-assigned hemolysis, no active cancer, no solid-organ or stem-cell transplant, MCV <90 fL, INR <1.5, creatinine <2.0 mg/dL), max 7. Bands 0-4 / 5 / 6-7 are pretest groups for severe ADAMTS13 deficiency, not percents or a plasma-exchange order. magent does not assay hemolysis. Cutoffs 30, 90, 1.5, and 2.0 do not score. ## Output Returns a total PLASMIC score from 0–7 and a pretest risk band: low (0–4), intermediate (5), or high (6–7) for severe ADAMTS13 deficiency. Exact cutoffs: platelets <30 (not 30), MCV <90 (not 90), INR <1.5 (not 1.5), creatinine <2.0 (not 2.0). The score is a pretest stratification tool, not a plasma-exchange order or percent probability. ## 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": [ "platelets_10e9_l", "hemolysis", "active_cancer", "solid_organ_or_stem_cell_transplant", "mcv_fl", "inr" ], "properties": { "inr": { "type": "number", "description": "INR (0.8-10).
