## What's an Apify Actor?

Actors are web data automations that power AI and operations. They run on the Apify platform to scrape websites, process data, connect APIs, and automate workflows.
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.

- **AI agents and MCP clients** — the [Apify MCP server](https://docs.apify.com/integrations/mcp.md) at `https://mcp.apify.com` (remote, streamable HTTP, OAuth on first use).
- **Agentic workflows and local Actor development** — [Agent Skills](https://apify.com/.well-known/agent-skills/index.json) with the [Apify CLI](https://docs.apify.com/cli/docs.md): `npm install -g apify-cli`, then `apify login`.
- **JavaScript/TypeScript projects** — the official [JS/TS client](https://docs.apify.com/api/client/js/docs.md): `npm install apify-client`.
- **Python projects** — the official [Python client](https://docs.apify.com/api/client/python/docs.md): `pip install apify-client`.
- **Any other language** — the [REST API](https://docs.apify.com/api/v2.md).

For usage examples, see the [API](#api) section below.

### Pay-Per-Event Pricing

This actor uses pay-per-event pricing. Event prices include Apify platform usage; users are not expected to pay a separate platform-usage pass-through charge for the configured pricing model.

- Tier: U1 — Tiny deterministic utility
- Primary event: `identifier-validated` at $0.00195 base
- Default max charge: $1.00
- Store discounts: FREE/BRONZE base, SILVER discounted, GOLD deepest approved discount

Event set:

- `actor-start`: base $0.00176, GOLD $0.00141. Upc Ean Isbn Normalizer: charged when actor start is completed. The price includes Apify platform usage; no separate usage pass-through is intended.
- `identifier-validated`: base $0.00195, GOLD $0.00156. Upc Ean Isbn Normalizer: charged when identifier validated is completed. The price includes Apify platform usage; no separate usage pass-through is intended.
- `report-generated`: base $0.02000, GOLD $0.01600. Upc Ean Isbn Normalizer: charged when report generated is completed. The price includes Apify platform usage; no separate usage pass-through is intended.

The actor accepts `actor-start` before work, accepts the primary event before each dataset row, and accepts the configured report event before writing report files. If `maxChargeUsd` or the live PPE limit blocks a charge, the corresponding row or report is not written.

### Public Task Concepts

- Extract UPC / EAN / ISBN rows from supplied public inputs
- Inventory UPC / EAN / ISBN fields across a capped sample
- Normalize UPC / EAN / ISBN evidence for delivery
- Flag missing UPC / EAN / ISBN data before delivery
- Export UPC / EAN / ISBN records with source URLs
  Normalize product identifiers for catalog workflows.

### What It Does

Strips formatting, detects UPC-A/EAN-13/ISBN-10/ISBN-13, validates check digits, converts ISBN-10 to ISBN-13, and optionally pads UPC-A bodies.

### Inputs

This actor exposes these input fields in `.actor/input_schema.json`:

- `inputRows`
- `fileUrl`
- `codeColumn`
- `outputFormat`
- `convertIsbn10`
- `padUpcA`
- `maxRows`
- `includeInvalidRows`
- `maxChargeUsd`

The exact default normalizes ISBN-10 `0-306-40615-2` and ISBN-13 `978-0-306-40615-7`, a real edition pair verified through the public Open Library Books API at 2026-07-12T05:48:00Z.

### Outputs

Dataset rows contain:

- `rowIndex`
- `originalCode`
- `normalizedCode`
- `detectedType`
- `convertedFrom`
- `checkDigitValid`
- `normalizationStatus`
- `warnings`
- `errors`

Sample outputs in `examples/output.sample.json` and `output.sample.json` were generated from `examples/input.tiny.json` through actor logic.

### Reports

After the configured report charge is accepted, the actor writes its Markdown, JSON, or CSV reports to the key-value store. A rejected report charge leaves those files unwritten.

### Public Task Concepts

- Normalize UPC / EAN / ISBN Normalizer records
- Validate UPC / EAN / ISBN Normalizer values in bulk
- Generate a small utility report for UPC / EAN / ISBN Normalizer

### Safe use

Use small capped runs first. Network paths are bounded; review output quality and costs before increasing limits.

# Actor input Schema
