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

What it computes

Sum fourteen caller-assigned Hamilton 1959 HAM-A items (each integer 0-4) and return the published 0-56 total. Does not apply later total-score severity bands.

When to use

When an agent already has Hamilton 1959 0-4 integers for the fourteen items and needs the published total. magent does not interview the patient, diagnose anxiety, or apply later 17/24 cutoffs.

When not to use

  • Not a medical device and not an anxiety diagnosis or treatment order.
  • Each of the fourteen items is a caller-assigned integer 0-4 (0 not present, 1 mild, 2 moderate, 3 severe, 4 very severe). magent does not interview the patient.
  • This is Hamilton 1959 HAM-A only (fourteen items; max 56). magent does not score GAD-7, PHQ-9, or Hamilton depression.
  • Hamilton 1959 published no total-score severity bands. This tool returns score and max_score only. It does not apply later 17/24 website or review cutoffs.

Formula

HAM-A = anxious_mood + tension + fears + insomnia + intellectual + depressed_mood + somatic_muscular + somatic_sensory + cardiovascular + respiratory + gastrointestinal + genitourinary + autonomic + interview_behavior; each caller-assigned 0-4; max 56; Hamilton 1959; no total-score severity bands

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/hamilton_anxiety 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.
