## 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.

## GraphQL Operation Cost Estimator

### Store Positioning

**Store title:** GraphQL Operation Cost Estimator

**Short description:** Estimate relative cost and complexity of GraphQL operations by analyzing operation documents against schemas, fragments, field depth, list multipliers, aliases, and configurable cost rules.

**SEO title:** GraphQL Operation Cost Estimator — API, schema, and developer QA

**SEO description:** Estimate relative cost and complexity of GraphQL operations by analyzing operation documents against schemas, fragments, field depth, list multipliers, aliases, and configurable cost rules. Use it to catch contract drift, schema mistakes, unsafe endpoint assumptions, and developer-tool quality issues before release.

### 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: A1 — API/developer QA
- Primary event: `schema-validated` at $0.00650 base
- Default max charge: $10.00
- Store discounts: FREE/BRONZE base, SILVER discounted, GOLD deepest approved discount

Event set:

- `actor-start`: base $0.00500, GOLD $0.00400. Graphql Operation Cost Estimator: charged when actor start is completed. The price includes Apify platform usage; no separate usage pass-through is intended.
- `schema-validated`: base $0.00650, GOLD $0.00520. Graphql Operation Cost Estimator: charged when schema validated is completed. The price includes Apify platform usage; no separate usage pass-through is intended.
- `contract-rule-checked`: base $0.00390, GOLD $0.00312. Graphql Operation Cost Estimator: charged when contract rule checked is completed. The price includes Apify platform usage; no separate usage pass-through is intended.
- `report-generated`: base $0.05000, GOLD $0.04000. Graphql Operation Cost Estimator: charged when report generated is completed. The price includes Apify platform usage; no separate usage pass-through is intended.

### Public Task Concepts

- Build a GraphQL Operation Cost stakeholder brief from source rows
- Prioritize GraphQL Operation Cost findings with evidence and confidence
- Summarize GraphQL Operation Cost metrics into recommended actions
- Prepare a GraphQL Operation Cost source table with uncertainty notes
- Export GraphQL Operation Cost decision rows for review

Parses supplied GraphQL operations and persisted-operation manifests, expands fields/fragments, applies configured field weights and list multipliers, and emits field-path cost diagnostics with operation totals.

### Inputs

- `schemaSdl`
- `introspectionJson`
- `operationDocuments`
- `operationUrls`
- `persistedOperationManifest`
- `costRules`
- `defaultFieldCost`
- `defaultListMultiplier`
- `maxDepth`
- `maxEstimatedCost`
- `includeFieldBreakdown`
- `includeFragmentExpansion`
- `timeoutMs`
- `maxChargeUsd`

### Outputs

Dataset fields: `sourceId`, `operationName`, `operationType`, `fieldPath`, `parentType`, `fieldName`, `depth`, `fieldWeight`, `listMultiplier`, `fragmentName`, `aliasName`, `estimatedFieldCost`, `estimatedOperationCost`, `complexityScore`, `thresholdExceeded`, `warning`, `passed`.

Reports: `graphql-operation-cost-report.md`, `operation-cost-summary.csv`, `field-cost-breakdown.json`, `high-cost-operations.json`, `cost-rule-audit.json`.

Use small capped runs first; live network checks should stay bounded and avoid secrets in inputs.

Live and local execution use the same pay-per-event billing guard: the actor-start event is accepted before analysis, each paid row is charged before dataset output, reports are charged before key-value-store output, and `maxChargeUsd` stops gracefully without leaking unpaid artifacts.

# Actor input Schema

## `schemaSdl` (type: `string`):

Schema Sdl controls GraphQL Operation Cost Estimator processing for the supplied inputs; keep values conservative for first runs.

# API

You can run this Actor programmatically using our API. Below are code examples in JavaScript, Python, and CLI, as well as the OpenAPI specification and MCP server setup.

## JavaScript example

```javascript
import { ApifyClient } from 'apify-client';

// Initialize the ApifyClient with your Apify API token
// Replace the '<YOUR_API_TOKEN>' with your token
const client = new ApifyClient({
    token: '<YOUR_API_TOKEN>',
});

// Prepare Actor input
const input = {};

// Run the Actor and wait for it to finish
const run = await client.actor("junipr/graphql-operation-cost-estimator").call(input);

// Fetch and print Actor results from the run's dataset (if any)
console.log('Results from dataset');
console.log(`💾 Check your data here: https://console.apify.com/storage/datasets/${run.defaultDatasetId}`);
const { items } = await client.dataset(run.defaultDatasetId).listItems();
items.forEach((item) => {

## CLI example

```bash
echo '{}' |
apify call junipr/graphql-operation-cost-estimator --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,junipr/graphql-operation-cost-estimator"
        }
    }
}

```

The hosted server signs you in with OAuth on first connect, so no API token belongs in this config. Clients without OAuth support can send an `Authorization: Bearer <APIFY_API_TOKEN>` header instead, using a token from API & Integrations in Apify Console (https://console.apify.com/settings/integrations).
