# Swede colposcopy score (Strander) Swede score Status: LIVE Price: $0.005 USDC `GET /api/calc/swede` HTML: https://magentlab.com/docs/swede Markdown: https://magentlab.com/docs/swede.md Not a medical device. Not a diagnosis, dose, or listing recommendation. ## What it computes Sum five caller-assigned Strander 2005 Swede integers (acetowhiteness, margins_surface, vessels, lesion_size, iodine; each 0-2; max 10) and return the published total and <5 / 5-7 / >=8 bands. ## When to use When an agent has already assigned Strander 2005 Table I 0-2 integers for acetowhiteness, margins and surface, vessels, lesion size, and iodine and needs the published Swede total and bands, not a CIN diagnosis, see-and-treat order, or Reid index. magent does not read the colposcope. ## When not to use - Not a medical device. magent does not diagnose CIN or high-grade dysplasia. - Inputs are caller-assigned Strander 2005 Table I integers (each 0, 1, or 2). magent does not read the colposcope. - Published derivation-set findings: score ≥5 identified all high-grade lesions (HGL); score ≥8 had 90% specificity for HGL. magent reports bands <5, 5-7, and >=8. Score 5 is 5-7. Score 8 is >=8. magent does not invent a see-and-treat order. - Not the Reid colposcopic index. Not a CIN diagnosis. ## Formula ``` Swede = acetowhiteness + margins_surface + vessels + lesion_size + iodine; each caller-assigned 0-2 (Strander 2005 Table I final rounded weights); max 10; bands <5, 5-7, >=8 ``` ## Citation [The performance of a new scoring system for colposcopy in detecting high-grade dysplasia in the uterine cervix](https://doi.org/10.1111/j.0001-6349.2005.00895.x) Strander B, Ellström-Andersson A, Franzén S, Milsom I, Rådberg T Acta Obstet Gynecol Scand. 2005;84(10):1013-1017 DOI: [10.1111/j.0001-6349.2005.00895.x](https://doi.org/10.1111/j.0001-6349.2005.00895.x) ## Worked example ### Distinct acetowhiteness and iodine, even margins, absent vessels, mid size Given: `acetowhiteness=2, iodine=2, lesion_size=1, margins_surface=2, vessels=1` 1. acetowhiteness 2 + margins_surface 2 + vessels 1 + lesion_size 1 + iodine 2 2. Score = 8 (max 10); swede_band >=8 ### All items 0 Given: `acetowhiteness=0, iodine=0, lesion_size=0, margins_surface=0, vessels=0` 1. acetowhiteness 0 + margins_surface 0 + vessels 0 + lesion_size 0 + iodine 0 2. Score = 0 (max 10); swede_band <5 ### All items 2 Given: `acetowhiteness=2, iodine=2, lesion_size=2, margins_surface=2, vessels=2` 1. acetowhiteness 2 + margins_surface 2 + vessels 2 + lesion_size 2 + iodine 2 2. Score = 10 (max 10); swede_band >=8 ## Also searched as - Swede score - Swede colposcopy score - Strander Swede score - Strander 2005 colposcopy score - Swede acetowhiteness iodine - colposcopy scoring system cervix - Swede high-grade dysplasia ## Parameters - `acetowhiteness` (integer, required): Caller-assigned Strander 2005 Table I acetowhiteness (integer 0-2): 0 none/transparent; 1 shady/milky; 2 distinct/stearin (opaque white). magent does not read the colposcope. - `margins_surface` (integer, required): Caller-assigned Strander 2005 Table I margins and surface (integer 0-2): 0 none/diffuse; 1 sharp but irregular/jagged/geographical (satellites); 2 sharp and even, surface-level difference (cuffing). magent does not read the colposcope. - `vessels` (integer, required): Caller-assigned Strander 2005 Table I vessels (integer 0-2): 0 fine/regular; 1 absent; 2 coarse or atypical. magent does not read the colposcope. - `lesion_size` (integer, required): Caller-assigned Strander 2005 Table I lesion size (integer 0-2): 0 <5 mm; 1 5-15 mm or 2 quadrants; 2 >15 mm or 3-4 quadrants or endocervically undefined. magent does not read the colposcope. - `iodine` (integer, required): Caller-assigned Strander 2005 Table I iodine staining (integer 0-2): 0 brown; 1 faintly or patchy yellow; 2 distinct yellow. magent does not read the colposcope. ## 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. Method: `POST /api/calc/swede` Max items: 25 Price: unit_amount + extra_item_amount * (n - 1) (unit 5000 atomic, extra 2000 atomic) Status: 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.

Returned before settlement; you are not charged. - HTTP 400 `invalid_swede_item`: acetowhiteness, margins_surface, vessels, lesion_size, and iodine must each be 0, 1, or 2 (Strander 2005). Returned before settlement; you are not charged. - HTTP 400 `invalid_items`: POST body must be a JSON object with only an items array Returned before settlement; you are not charged. - HTTP 400 `invalid_item_count`: items must be an array of 1 to 25 objects Returned before settlement; you are not charged. - HTTP 400 `invalid_item`: each items entry must be a JSON object Returned before settlement; you are not charged. Shared HTTP 402 and 503: https://magentlab.com/docs/payments ## Related tools - [RMI](https://magentlab.com/docs/rmi) — Compute the Jacobs 1990 risk of malignancy index as ultrasound score × menopausal score × CA125 (U/ml), then whether that product exceeds the published cutoff of 200. ## 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. - GET the tool with Accept: application/json (do not send Accept: text/html unless you want the human paywall). - HTTP 402 means you have not paid. Decode the base64 PAYMENT-REQUIRED header. HTTP 503 is not a new quote. - Sign accepts[0] (exact, EIP-3009) with validBefore = now + maxTimeoutSeconds (600 seconds), or accepts[1] (batch-settlement deposit/voucher) on product GET. Ping and POST {items} stay exact. Magent retries transient facilitator 429/5xx before answering. - Retry the same URL with PAYMENT-SIGNATURE (base64 JSON of accepted and payload). Magent attaches canonical extensions.bazaar on CDP verify/settle; echoing 402 bazaar is optional. - Success is HTTP 200 JSON plus PAYMENT-RESPONSE. exact settles before the tool. batch-settlement verifies (and deposit-settles) before the tool and commits the charge after HTTP 2xx. HTTP 503: retry the same PAYMENT-SIGNATURE. Mint a new exact nonce only after a new HTTP 402. - offered `exact` on eip155:8453: Fixed-price USDC on Base. The buyer authorizes the advertised amount (EIP-3009). magent settles before the tool runs (paymentFlow upfront). extra.assetTransferMethod=eip3009 extra.paymentFlow=upfront. - offered `batch-settlement` on eip155:8453: Payment-channel vouchers claimed later in batches. Exact stays accepts[0]. Same-path POST {items} is still exact. extra.assetTransferMethod=eip3009 extra.paymentFlow=authorization. - not offered `upto`: Not offered. Usage-based: buyer authorizes a ceiling, seller settles the actual amount after work. Reserved for a future metered tool. Not for current calculators or code search. Same-path POST {items} is still scheme exact: one EIP-3009 authorization for GET unit plus $0.002 per extra item. That is not x402 batch-settlement (payment channels / vouchers). Shared HTTP 402 and 503 table: https://magentlab.com/docs/payments Stdio MCP (one process per host): https://magentlab.com/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.
