## Pricing

from $6.50 / 1,000 endpoint testeds

This Actor is paid per event. You are not charged for the Apify platform usage, but only a fixed price for specific events.

## 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.

## gRPC Reflection Extractor

### Store Positioning

**Store title:** gRPC Reflection Extractor

**Short description:** Use public gRPC server reflection, when enabled, to inventory services, methods, request/response types, streaming flags, packages, and descriptor metadata without invoking business methods.

**SEO title:** gRPC Reflection Extractor — API, schema, and developer QA

**SEO description:** Use public gRPC server reflection, when enabled, to inventory services, methods, request/response types, streaming flags, packages, and descriptor metadata without invoking business methods. Use it to catch contract drift, schema mistakes, unsafe endpoint assumptions, and developer-tool quality issues before release.

### Fixed-Inclusive PPE 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: `endpoint-tested` 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. Grpc Reflection Extractor: charged when actor start is completed. The price includes Apify platform usage; no separate usage pass-through is intended.
- `endpoint-tested`: base $0.00650, GOLD $0.00520. Grpc Reflection Extractor: charged when endpoint tested is completed. The price includes Apify platform usage; no separate usage pass-through is intended.
- `contract-rule-checked`: base $0.00390, GOLD $0.00312. Grpc Reflection Extractor: 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. Grpc Reflection Extractor: charged when report generated is completed. The price includes Apify platform usage; no separate usage pass-through is intended.

### Public Task Concepts

- Validate gRPC Reflection Extractor before release
- Run a bounded gRPC Reflection Extractor QA check
- Audit grpc issues across supplied public inputs
- Extract evidence-backed grpc rows for client QA
- Generate developer QA evidence for gRPC Reflection Extractor

Extracts supplied-input gRPC reflection service and method inventory without invoking business methods, preserving package names, request/response types, streaming flags, descriptor files, and reflection errors.

### Inputs

- `endpoints`
- `useTls`
- `plaintext`
- `authorityOverride`
- `metadataHeaders`
- `serviceFilters`
- `includeFileDescriptors`
- `includeDependencyFiles`
- `exportProtoLikeSummary`
- `maxServices`
- `timeoutMs`
- `maxChargeUsd`

### Outputs

Dataset fields: `endpoint`, `packageName`, `serviceName`, `methodName`, `requestType`, `responseType`, `clientStreaming`, `serverStreaming`, `fileName`, `dependencyFiles`, `descriptorFetched`, `reflectionStatus`, `errorType`, `warning`.

Reports: `grpc-reflection-extraction-report.md`, `grpc-service-inventory.json`, `grpc-method-inventory.csv`, `grpc-descriptor-summary.json`, `grpc-reflection-errors.json`.

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

# Actor input Schema

## `endpoints` (type: `array`):

Endpoints controls gRPC Reflection Extractor processing for the supplied inputs; keep values conservative for first runs.

## `useTls` (type: `boolean`):

Use TLS controls gRPC Reflection Extractor processing for the supplied inputs; keep values conservative for first runs.

## `plaintext` (type: `boolean`):

Supplied plaintext to analyze directly.

## `authorityOverride` (type: `string`):

Authority Override controls gRPC Reflection Extractor processing for the supplied inputs; keep values conservative for first runs.

## `metadataHeaders` (type: `object`):

Metadata Headers controls gRPC Reflection Extractor processing for the supplied inputs; keep values conservative for first runs.

## `serviceFilters` (type: `array`):

## `includeFileDescriptors` (type: `boolean`):

Include file descriptors in output rows or reports when available.

## `includeDependencyFiles` (type: `boolean`):

// Prepare Actor input
const input = {};

// Run the Actor and wait for it to finish
const run = await client.actor("junipr/grpc-reflection-extractor").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) => {
    console.dir(item);
});

## CLI example

```bash
echo '{}' |
apify call junipr/grpc-reflection-extractor --silent --output-dataset

```

## MCP server setup

```json
{
    "mcpServers": {
        "apify": {
            "type": "http",
            "url": "https://mcp.apify.com/?tools=fetch-actor-details,junipr/grpc-reflection-extractor"
        }
    }
}

```

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).
