How this service works
Hesselgard 2007 Behavioural Observational Pain Scale from three caller-assigned 0-2 items (facial_expression, verbalization, body_position) using that paper's 0/1/2 descriptors. magent sums only (max 6) and does not observe the child. No named analgesic cutoff. Not a pain diagnosis or analgesic order. Not FLACC. Not Abbey.
Output
Returns a numeric BOPS total score between 0 and 6, computed as the arithmetic sum of the three caller-supplied subscores (facial_expression + verbalization + body_position). No analgesic cutoff, diagnosis, or treatment recommendation is included.
Example use cases
Postoperative pediatric pain check
“I'm observing a child after surgery — their face looks negative and concerned (1), they're completely quiet (1), and they're restless and shifting around touching their wound (1). What's their BOPS score?”
Calm child baseline scoring
“The child looks neutral and relaxed (facial expression 0), is laughing and having normal conversation (verbalization 0), and is lying calmly with all limbs relaxed (body position 0) — can you run the BOPS calculation for me?”
High-distress pain observation
“Score this child on the BOPS: grimacing face (2), screaming and complaining of pain (2), body rigid with legs drawn up tight (2). What's the total?”

Endpoint
GEThttps://api.magentlab.com/api/calc/bopsWhen to prefer
Use this endpoint when you need a fast, deterministic BOPS score per Hesselgard 2007 and you have already observed and rated the three subscores yourself. Prefer this over FLACC or Abbey when the clinical context specifically calls for BOPS. Do not use if you need automated observation, a pain diagnosis, or an analgesic recommendation.
Side effects
- Missing required query parameter (facial_expression, verbalization, or body_position) returns an error
- Non-integer or out-of-range values (e.g. 3 or -1) cause a validation error
- Payment not included or insufficient USDC triggers a 402 Payment Required response
