The Actor is free to use, and you only pay for the Apify platform usage, which gets cheaper the higher subscription plan you have.

Actors are a software tools running on the Apify platform, for all kinds of web data extraction and automation use cases. In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours, and optionally produces a well-defined JSON output, datasets with results, or files in key-value store. In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server. Actors are written with capital "A". ## How to integrate an Actor? If asked about integration, you help developers integrate Actors into their projects. You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready. The best way to integrate Actors is as follows. In JavaScript/TypeScript projects, use official [JavaScript/TypeScript client](https://docs.apify.com/api/client/js/docs.md): ```bash npm install apify-client ``` In Python projects, use official [Python client library](https://docs.apify.com/api/client/python/docs.md): ```bash pip install apify-client ``` In shell scripts, use [Apify CLI](https://docs.apify.com/cli/docs.md): ````bash # MacOS / Linux curl -fsSL https://apify.com/install-cli.sh | bash # Windows irm https://apify.com/install-cli.ps1 | iex ```bash In AI frameworks, you might use the [Apify MCP server](https://docs.apify.com/integrations/mcp.md). If your project is in a different language, use the [REST API](https://docs.apify.com/api/v2.md). For usage examples, see the [API](#api) section below. For more details, see Apify documentation as [Markdown index](https://docs.apify.com/llms.txt) and [Markdown full-text](https://docs.apify.com/llms-full.txt). # README ## Used Camera Gear Valuation Engine Produces transparent valuation ranges for used camera bodies, lenses, and flashes. ### Inputs Provide `targets` and verified sold `comps`; optional JSON/CSV URLs may supplement them. Non-USD records require manual FX rates. ### Outputs Each target becomes a Dataset record. `OUTPUT` summarizes the run and `REPORT.html` shows raw and normalized comp evidence. ### Responsible-use notes This is not an appraisal or authenticity service. Shutter count is adjusted only for bodies. The Actor never silently turns a sale into an “excellent/full-set equivalent”; original sold prices remain visible and accessories are priced only from explicit user values. ### Local validation ```bash npm ci npm test npm run check npm run sample ```` `npm run sample` runs the real Apify SDK entry point with local storage and writes Dataset, `OUTPUT`, and `REPORT.html`. # Actor input Schema ## `targets` (type: `array`): Camera bodies, lenses, flashes, or related gear. ## `comps` (type: `array`): Use completed sales, not active asking prices. ## `sourceUrls` (type: `array`): Public or authorized URLs returning records. No login bypass is attempted. ## `targetCurrency` (type: `string`): Target currency ## `fxRates` (type: `object`): Example: {"EUR\_USD": 1.08}. Required for non-target currencies. ## `halfLifeDays` (type: `integer`): Comparable recency half-life ## `minimumSimilarity` (type: `number`): Minimum comparable similarity ## `includeComparableEvidence` (type: `boolean`): Include comparable evidence in Dataset ## Actor input object example ```json { "targets": [ { "id": "sony-a7iv-20k", "itemType": "camera body", "brand": "Sony", "model": "A7 IV", "mount": "E", "condition": "excellent", "shutterCount": 20000, "includedAccessories": [ "battery", "charger" ], "accessoryValues": { "charger": 35 } }, { "id": "sony-24-70-gm2", "itemType": "lens", "brand": "Sony", "model": "FE 24-70mm F2.8 GM II", "mount": "E", "condition": "good", "includedAccessories": [ "hood", "front cap", "rear cap" ] } ], "comps": [ { "id": "c1", "itemType": "camera body", "brand": "Sony", "model": "A7 IV", "mount": "E", "condition": "excellent", "shutterCount": 18000, "soldPrice": 1900, "currency": "USD", "soldAt": "2026-07-01", "saleVerified": true, "includedAccessories": [ "battery", "charger" ], "source": "auction export" }, { "id": "c2", "itemType": "camera body", "brand": "Sony", "model": "A7 IV", "mount": "E", "condition": "good", "shutterCount": 30000, "soldPrice": 1650, "currency": "USD", "soldAt": "2026-06-10", "saleVerified": true, "includedAccessories": [ "battery" ] }, { "id": "c3", "itemType": "camera body", "brand": "Sony", "model": "A7IV", "mount": "E", "condition": "mint", "shutterCount": 5000, "soldPrice": 2100, "currency": "USD", "soldAt": "2026-05-15", "saleVerified": true, "includedAccessories": [ "battery", "charger", "box" ] }, { "id": "l1", "itemType": "lens", "brand": "Sony", "model": "FE 24-70mm F2.8 GM II", "mount": "E", "condition": "excellent", "soldPrice": 1810, "currency": "USD", "soldAt": "2026-07-03", "saleVerified": true, "includedAccessories": [ "hood", "caps" ] }, { "id": "l2", "itemType": "lens", "brand": "Sony", "model": "24-70 GM2", "mount": "E", "condition": "good", "soldPrice": 1580, "currency": "USD", "soldAt": "2026-06-20", "saleVerified": true, "includedAccessories": [ "hood", "caps" ] }, { "id": "l3", "itemType": "lens", "brand": "Sony", "model": "FE 24-70 2.8 GM II", "mount": "E", "condition": "good", "soldPrice": 1625, "currency": "USD", "soldAt": "2026-05-28", "saleVerified": true, "includedAccessories": [ "caps" ] } ], "sourceUrls": [], "targetCurrency": "USD", "fxRates": {}, "halfLifeDays": 180, "minimumSimilarity": 0.56, "includeComparableEvidence": true } ``` # Actor output Schema ## `results` (type: `string`): No description ## `output` (type: `string`): No description ## `report` (type: `string`): No description # API You can run this Actor programmatically using our API.
