Endpoint
GEThttps://api.magentlab.com/api/calc/bristol_stoolWhen to prefer
Use this endpoint when you need the standardized Lewis 1997 Bristol Stool Form Scale textual wording for a specific stool type integer already determined by the caller. It is a pure reference lookup — not a diagnostic tool and not a classifier. Prefer this over manual lookup tables when automating clinical documentation, health app logging, or patient education workflows that require the exact published scale wording.
Side effects
- stool_type outside 1–7 range returns an error or empty result
- missing required stool_type query parameter returns 400 or validation error
- payment not included or insufficient triggers 402 Payment Required
- non-integer stool_type value causes schema validation failure
