# Dutch Lipid Clinic Network (DLCN) Familial Hypercholesterolaemia Score > Dutch Lipid Clinic Network (DLCN) Familial Hypercholesterolaemia Score 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). Calculates the Dutch Lipid Clinic Network (Nordestgaard 2013 Table 1) FH score from LDL cholesterol, family history, clinical history, physical findings, and DNA mutation status. ## Facts - Endpoint: GET https://api.magentlab.com/api/calc/dutch_fh - 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/dutch-lipid-clinic-network-dlcn-familial-hypercholesterolaemia-score-f04bed09 - Structured record (JSON): https://api.zero.xyz/v1/capabilities/cap_M02njchKB5_pvWer6mfmm 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 dutch-lipid-clinic-network-dlcn-familial-hypercholesterolaemia-score-f04bed09 ``` Example prompt: Calculate the Dutch Lipid Clinic Network FH score for a patient with an LDL of 5.8 mmol/L, premature coronary heart disease, a first-degree relative with premature CHD, no tendon xanthoma, no corneal arcus, no child with elevated LDL, no first-degree relative with LDL above the 95th percentile, no first-degree relative with xanthoma or arcus, and a confirmed causative LDLR mutation. ## When to prefer this Use this endpoint when you need to programmatically apply the adult Dutch Lipid Clinic Network (Nordestgaard 2013 Table 1) FH scoring algorithm — not the Simon Broome, MEDPED, or homozygous FH criteria — and all clinical findings have already been assessed by a clinician or extracted from structured EHR data. Ideal for automating lipid clinic workflows, EHR decision-support, or risk-stratification pipelines where LDL and family/clinical/DNA flags are available as structured inputs. ## Known failure modes - Missing required boolean flags returns a validation error - Supplying both ldl_mmol_l and ldl_mg_dl simultaneously returns an error (exactly one must be provided) - LDL value outside accepted range (mmol/L 1–20 or mg/dL 40–800) may be rejected or return an unexpected score - Misclassified caller-assigned clinical findings (e.g., incorrect age cutoffs for premature CHD) produce an incorrect score — garbage-in-garbage-out with no server-side guard - HTTP 402 returned if payment credentials are missing or invalid ## How this service works Dutch Lipid Clinic Network (Nordestgaard 2013 Table 1) familial hypercholesterolaemia score. One LDL (mmol/L or mg/dL / 38.67) plus family, clinical, physical, and DNA groups; per group only the highest. Max 26. Definite >8, probable 6-8, possible 3-5, unlikely 0-2. Score 8 (mutation alone) is probable. Adult Table 1 only; not Simon Broome, not MEDPED, not homozygous FH. magent does not assay lipids, examine tendons or arcus, or sequence genes. Not a medical device and not a diagnosis of FH. ## Output Returns the total DLCN FH score (0–26) broken down by group (lipid, family, clinical, physical, DNA), with per-group highest-item selection applied, plus a categorical FH probability label: definite (>8), probable (6–8), possible (3–5), or unlikely (0–2). ## 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": [ "first_degree_premature_chd", "first_degree_ldl_gt_95th", "first_degree_xanthoma_or_arcus", "child_ldl_gt_95th", "premature_chd", "premature_cerebral_or_pvd", "tendon_xanthoma", "corneal_arcus_age_lt_45", "causative_mutation_ldlr_apob_pcsk9" ], "properties": { "ldl_mg_dl": { "type": "number", "description": "LDL cholesterol in mg/dL (40-800).
