FLIPI 2004 Calculator (Follicular Lymphoma International Prognostic Index)
x402
FLIPI 2004 Calculator (Follicular Lymphoma International Prognostic Index) 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 Solal-Céligny 2004 FLIPI score (0–5) and risk category (low/intermediate/high) from five binary clinical flags for follicular lymphoma prognosis.

How this service works
Solal-Céligny 2004 FLIPI: age >60, Ann Arbor III–IV, hemoglobin <120 g/L, nodal areas >4, LDH above ULN; 1 point each, max 5. Low 0–1, intermediate 2, high ≥3. Deterministic published score with citation; not a follicular-lymphoma diagnosis or treatment choice; FLIPI 2004 not FLIPI-2. magent does not stage lymphoma, assay hemoglobin, count nodal sites, or measure LDH.
Output
Returns the numeric FLIPI total score (0–5, one point per positive flag) and the corresponding risk category: low (0–1), intermediate (2), or high (≥3), based on the Solal-Céligny 2004 publication. The endpoint performs only arithmetic on the five caller-supplied boolean inputs.
Example use cases
Pre-treatment risk stratification
“My patient with follicular lymphoma is 65 years old, has stage III disease, hemoglobin of 108 g/L, 6 involved nodal areas, and elevated LDH — can you calculate their FLIPI score and tell me if they're low, intermediate, or high risk?”
Clinical trial eligibility screening
“For our FL trial that requires high-risk FLIPI, check whether a patient aged 58, Ann Arbor stage IV, hemoglobin 130 g/L, 3 nodal sites, and normal LDH qualifies — give me their FLIPI total and risk group.”
Automated EHR prognostic annotation
“Given these extracted flags for a new follicular lymphoma case — age over 60: yes, stage III–IV: yes, Hgb under 120: no, nodal sites over 4: no, LDH elevated: yes — compute the FLIPI score and risk category so I can annotate the chart.”
Technical details
Endpoint
GEThttps://api.magentlab.com/api/calc/flipiWhen to prefer
Use this endpoint when you need a deterministic, cited implementation of the original 2004 Solal-Céligny FLIPI (not FLIPI-2) and already have the five binary clinical flags assigned from external clinical data. It is appropriate for automating prognostic scoring in oncology workflows, annotating EHR data, or checking trial eligibility criteria that reference FLIPI. Do not use it to stage lymphoma, measure hemoglobin, count nodal sites, or measure LDH — those must be resolved upstream.
Side effects
- Missing required boolean query parameter returns a validation error
- Invalid (non-boolean) value for any parameter causes a 400-level error
- Payment not provided or insufficient results in x402 payment required response
- All five flags false returns score 0 / low risk (expected, not an error)
