Not a medical device. Not a diagnosis, dose, or listing recommendation.

What it computes

Sum fourteen caller-assigned Rodeghiero 2010 ISTH/SSC BAT symptom integers (Table S1, 0-4; cns_bleeding 0, 3, or 4) and return the published total (max 56). Does not apply later abnormal cutoffs.

When to use

When an agent has already assigned Rodeghiero 2010 Table S1 integers for all fourteen symptoms and needs the published sum. magent does not take a bleeding history, diagnose VWD, or apply Elbatarny 2014 / WFH abnormal cutoffs.

When not to use

  • Not a medical device and not a diagnosis of VWD or any inherited bleeding disorder.
  • magent does not take the bleeding history. Each of the fourteen symptoms is a caller-assigned integer from Rodeghiero 2010 Table S1.
  • cns_bleeding is 0, 3, or 4 only (never; subdural, any intervention; intracerebral, any intervention). Grades 1 and 2 are not used in Table S1.
  • This 2010 proposal letter did not identify an abnormal bleeding score. magent returns score and max_score only and does not apply later Elbatarny 2014 or WFH ≥4 male / ≥6 female / ≥3 child cutoffs.
  • Negative scores for surgery, tooth extraction, and postpartum bleeding are not in this bleeding score. Only the most severe score ever recorded per symptom, and only symptoms before or at diagnosis, are caller-side.

Formula

ISTH/SSC BAT = epistaxis + cutaneous + minor_wounds + oral_cavity + gi_bleeding + hematuria + tooth_extraction + surgery + menorrhagia + postpartum_hemorrhage + muscle_hematomas + hemarthrosis + cns_bleeding + other_bleeding; each caller-assigned 0-4 from Rodeghiero 2010 Table S1 (cns_bleeding 0, 3, or 4 only); max 56; no abnormal cutoff in this letter

Worked example

All fourteen symptoms 0

Given: cns_bleeding=0cutaneous=0epistaxis=0gi_bleeding=0hemarthrosis=0hematuria=0menorrhagia=0minor_wounds=0muscle_hematomas=0oral_cavity=0other_bleeding=0postpartum_hemorrhage=0surgery=0tooth_extraction=0

  1. Each Table S1 symptom integer is 0
  2. Score = 0 (max 56). This letter published no abnormal cutoff.

Epistaxis 4, remaining symptoms 0

Given: cns_bleeding=0cutaneous=0epistaxis=4gi_bleeding=0hemarthrosis=0hematuria=0menorrhagia=0minor_wounds=0muscle_hematomas=0oral_cavity=0other_bleeding=0postpartum_hemorrhage=0surgery=0tooth_extraction=0

  1. epistaxis 4; remaining thirteen items 0
  2. Score = 4 (max 56)

CNS bleeding 4, remaining symptoms 0

Given: cns_bleeding=4cutaneous=0epistaxis=0gi_bleeding=0hemarthrosis=0hematuria=0menorrhagia=0minor_wounds=0muscle_hematomas=0oral_cavity=0other_bleeding=0postpartum_hemorrhage=0surgery=0tooth_extraction=0

  1. cns_bleeding 4 (intracerebral, any intervention); remaining thirteen items 0
  2. Score = 4 (max 56). Table S1 does not use CNS grades 1 or 2.

Bulk (POST)

POST the same path with a JSON items array. The first item is the GET unit; each additional item is $0.002. Invalid items return HTTP 400 before settlement.

POST /api/calc/isth_bat Max 25 unit_amount + extra_item_amount * (n - 1) extra $0.002 PREVIEW

  • 1 to 25 items. Each item uses the same keys as the GET query parameters.
  • POST of 1 item costs the same as GET. Lists longer than 25: chunk into multiple POSTs. Extra items still execute; do not pad dummy rows.
  • The first invalid item fails the whole request (index in the 400 JSON). You are not charged.
  • HTTP 200 is {count, path, items}. Each items[i] is the GET 200 body for that row.
  • Catalog misses (empty matches, found=false) stay paid 200s inside that slot.
  • x402 resource URL is this path plus n and body_sha256. Browsers that prefer text/html get the same paywall as GET; Pay retries POST with the same items.

Payment

Unpaid requests return HTTP 402 even if query parameters or POST items are missing or invalid, so CDP and agents can index the path. After a PAYMENT-SIGNATURE, invalid params return HTTP 400 JSON before settlement. magent does not charge. Fix the params, then request a new 402 quote for that complete URL. Catalog misses (empty matches, found=false) are valid paid 200s. Unpaid valid requests return HTTP 402 with a base64 PAYMENT-REQUIRED header. HTTP 503 is not a new quote: retry the same PAYMENT-SIGNATURE. Full handshake and shared payment errors: Payments. Stdio MCP: /docs/mcp.

Guarantees

  • HTTP 402 is unpaid, including a missing query. After PAYMENT-SIGNATURE, invalid parameters return HTTP 400 before settlement. You are not charged. HTTP 402 never includes the tool JSON.
  • exact: settlement finishes before the tool (paymentFlow upfront). batch-settlement: verify/deposit before the tool; chargedCumulativeAmount commits after HTTP 2xx. Uncertain or failed settlement fails closed (HTTP 503). Retry the same PAYMENT-SIGNATURE.
  • HTTP 402 is unpaid only. Do not sign a second authorization because of a 503.
  • Execution is timeout-bounded and concurrency-capped.
  • Calculator inputs are stored encrypted for allowlisted operators (Magent Console). They are not in public logs, SSH lookups, catalog, or rollups. Request logs store path without query.
