## What's an Apify Actor?

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.md):

```bash
npm install apify-client
```

In Python projects, use official [Python client library](https://docs.apify.com/api/client/python.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/platform/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

## 🧰 OpenAPI Spec Scraper — API Directory → Agent-Tool / RAG Dataset

**Turn the world's machine-readable APIs into a clean, LLM-agent-ready dataset. Bulk-scrape the [apis.guru](https://apis.guru) directory (2,500+ public API specs) — or any OpenAPI/Swagger URL — and get normalized rows, one per endpoint: method, path, summary, parameters, auth scheme, server, and tags. Perfect for building agent tool catalogs, MCP servers, and RAG knowledge bases. Monitor the directory for newly-added APIs.**

No login, no anti-bot — the directory and specs are public JSON.

---

### What does it do?

Most spec converters take **one** pasted spec. This actor works on the **bulk directory axis**: point it at apis.guru (search or take the top N), and it fetches each API's OpenAPI/Swagger spec and **normalizes** it into ready-to-load rows.

- 📚 **2,500+ APIs** in the apis.guru directory (or your own spec URLs).
- 🔧 **One row per endpoint** (agent-tool ready): `method`, `path`, `operation_id`, `summary`, `parameters`, `auth`, `tags`, `server` — or one row per API with an `endpoints[]` array.
- 🔔 **Monitor mode** — alert when new APIs are added to the directory.

---

### What data does it extract?

**Per endpoint** (`emitMode: per-endpoint`): `api`, `api_title`, `server`, `auth_schemes`, `method`, `path`, `operation_id`, `summary`, `tags`, `parameters[]` (`{name, in, required, type}`), `request_body_required`, `response_codes`, `scraped_at`.

**Per API** (`emitMode: per-api`): `api`, `title`, `description`, `version`, `spec_version`, `server`, `auth_schemes`, `endpoint_count`, `endpoints[]`.

---

### Who is it for?

- 🤖 **AI agent / tool builders & MCP authors** assembling machine-usable tool catalogs.
- 📚 **RAG / knowledge-base builders** indexing API documentation as structured text.
- 🧑‍💻 **Developer-tooling teams** building API search, SDKs, and integrations.

### How to use it (step by step)

1. Click **Try for free**.
2. **Search** the directory (e.g. `stripe`, `google`, `weather`) — or paste **spec URLs** / **API names**.
3. Pick the **output shape** (per-endpoint is agent-tool ready).
4. Click **Start**, then open the **Dataset** tab to view/export.
5. *(Optional)* set **monitorMode** + a **Schedule** to catch newly-added APIs.

#### Quick start

```json
{ "searchTerm": "stripe", "emitMode": "per-endpoint" }
````

#### Bulk-directory example

```json
{ "maxApis": 200, "emitMode": "per-endpoint", "includeParameters": true }
```

***

### Input

| Field | What it does |
|-------|--------------|
| `searchTerm` | filter the apis.guru directory by name/title |
| `apiNames` | specific directory keys (e.g. `stripe.com`) |
| `specUrls` | any raw OpenAPI/Swagger spec URLs |
| `emitMode` | `per-endpoint` (agent-tool ready) · `per-api` |
| `includeParameters`, `includeSchemas` | enrich each endpoint |
| `maxApis` | cap on directory APIs (0 = all matching) |
| `monitorMode`, `alertOnNewApi` | recurring new-API watcher + alerts |
| `webhookUrl`, `slackWebhookUrl`, `emailRecipients` | alert channels |
| `proxyConfiguration`, `requestConcurrency` | proxy + parallelism |

***

### Output

One dataset record per endpoint (or per API). Export to **JSON, CSV, Excel, HTML, or RSS** — or fetch JSONL via the **Apify API** to load straight into an agent/RAG pipeline.

***

### How much does it cost?

Pay-per-event — you pay for what you pull:

| Event | What it covers | Suggested price |
|-------|----------------|-----------------|
| `lot-scraped` | each endpoint (or API) row returned | ~$0.001 / row |
| `monitor-run-completed` | each scheduled watch run | ~$0.05 / run |
| `new-lot-detected` | each newly-added API | ~$0.02 / API |
| `alert-delivered` | each Slack/email/webhook push | ~$0.005 / alert |

*(Final per-event prices are set on the actor's pricing page.)*

***

### Is it legal?

The apis.guru directory and the linked specs are **public, openly-licensed API descriptions** — no personal data. You're responsible for your use: review apis.guru's terms and each spec's own license/terms before redistributing.

***

### FAQ

**OpenAPI 3 and Swagger 2?**
Both — the normalizer handles `openapi` 3.x and `swagger` 2.0 (server, auth, parameters).

**Can I use a spec that isn't in the directory?**
Yes — pass its URL in `specUrls`.

**What's the best output for an AI agent?**
`per-endpoint` — each row is a self-contained tool descriptor.

**How do I export?**
JSON / JSONL, CSV, Excel, HTML, or RSS from the Dataset tab, or via the Apify API.

# Actor input Schema

## `searchTerm` (type: `string`):

Filter the apis.guru directory by API name or title (e.g. 'google', 'stripe', 'weather'). Leave empty to take the first N APIs.

## `apiNames` (type: `array`):

Exact-ish directory keys to fetch (e.g. 'stripe.com', 'github.com'). Substring match.

## `specUrls` (type: `array`):

Any OpenAPI/Swagger spec URLs (JSON) to normalize directly — works for specs not in the directory (e.g. a raw GitHub spec).

## `emitMode` (type: `string`):

Per-endpoint = one row per API endpoint (agent-tool / RAG ready). Per-api = one row per API with an endpoints array.

## `includeParameters` (type: `boolean`):

Include each endpoint's parameters (name, in, required, type).

## `includeSchemas` (type: `boolean`):

Include each endpoint's response status codes.

## `maxApis` (type: `integer`):

Cap on APIs from the directory (the full directory is ~2,500). 0 = all matching.

## `monitorMode` (type: `boolean`):

Recurring watcher: diff the directory against the prior run and output/alert ONLY newly-added APIs. Pair with a Schedule.

## `alertOnNewApi` (type: `boolean`):

In monitor mode, alert for each newly-added API.

## `webhookUrl` (type: `string`):

POST endpoint for new-API alerts.

## `slackWebhookUrl` (type: `string`):

Slack incoming-webhook URL.

## `emailRecipients` (type: `array`):

Emails for the new-API digest (via apify/send-mail).

## `proxyConfiguration` (type: `object`):

Proxy settings. The directory + specs are public; datacenter rotation is plenty.

## `requestConcurrency` (type: `integer`):

Max parallel spec fetches.

## `diagnose` (type: `boolean`):

Dev only. Logs the directory size + the first normalized API/endpoint, then exits.

## Actor input object example

```json
{
  "emitMode": "per-endpoint",
  "includeParameters": true,
