## Installation [#installation]

The official Ruby SDK is maintained in the Firecrawl monorepo at [apps/ruby-sdk](https://github.com/firecrawl/firecrawl/tree/main/apps/ruby-sdk).

To install the Firecrawl Ruby SDK, add it to your project:

<Tabs>
  <Tab title="Bundler">
    Add to your `Gemfile`:

    ```ruby
    gem "firecrawl-sdk", "~> 1.0"
    ```

    Then run:

    ```bash
    bundle install
    ```
  </Tab>

  <Tab title="Gem install">
    ```bash
    gem install firecrawl-sdk
    ```
  </Tab>
</Tabs>

<Note>
  Requires Ruby 3.0 or later.
</Note>

## Usage [#usage]

1. Get an API key from [firecrawl.dev](https://firecrawl.dev)
2. Set the API key as an environment variable named `FIRECRAWL_API_KEY`, or pass it directly with `Firecrawl::Client.new(api_key: ...)`

Here is a quick example using the current SDK API surface:

```ruby
require "firecrawl"

client = Firecrawl::Client.from_env

doc = client.scrape(
  "https://firecrawl.dev",
  Firecrawl::Models::ScrapeOptions.new(formats: ["markdown"])
)

job = client.crawl(
  "https://firecrawl.dev",
  Firecrawl::Models::CrawlOptions.new(limit: 5)
)

puts doc.markdown
puts "Crawled pages: #{job.data&.size || 0}"
```

### Scraping a URL [#scraping-a-url]

To scrape a single URL, use the `scrape` method.

```ruby
doc = client.scrape(
  "https://firecrawl.dev",
  Firecrawl::Models::ScrapeOptions.new(
    formats: ["markdown", "html"],
    only_main_content: true,
    wait_for: 5000
  )
)

puts doc.markdown
puts doc.metadata["title"]
```

#### JSON Extraction [#json-extraction]

Extract structured JSON via the `scrape` endpoint by including a `json` format with a prompt and schema:

```ruby
doc = client.scrape(
  "https://example.com/product",
  Firecrawl::Models::ScrapeOptions.new(
    formats: [
      {
        "type" => "json",
        "prompt" => "Extract the product name and price",
        "schema" => {
          "type" => "object",
          "properties" => {
            "name" => { "type" => "string" },
            "price" => { "type" => "number" }
          }
        }
      }
    ]
  )
)

puts doc.json
```

### Crawling a Website [#crawling-a-website]

To crawl a website and wait for completion, use `crawl`. It auto-polls until the job finishes.

```ruby
job = client.crawl(
  "https://firecrawl.dev",
  Firecrawl::Models::CrawlOptions.new(
    limit: 50,
    max_discovery_depth: 3,
    scrape_options: Firecrawl::Models::ScrapeOptions.new(
      formats: ["markdown"]
    )
  )
)

puts "Status: #{job.status}"
puts "Progress: #{job.completed}/#{job.total}"

job.data&.each do |page|
  puts page.metadata["sourceURL"]
end
```

### Start a Crawl [#start-a-crawl]

Start a job without waiting using `start_crawl`.

```ruby
response = client.start_crawl(
  "https://firecrawl.dev",
  Firecrawl::Models::CrawlOptions.new(limit: 100)
)

puts "Job ID: #{response.id}"
```

### Checking Crawl Status [#checking-crawl-status]

Check crawl progress with `get_crawl_status`.

```ruby
status = client.get_crawl_status(response.id)
puts "Status: #{status.status}"
puts "Progress: #{status.completed}/#{status.total}"
```

### Cancelling a Crawl [#cancelling-a-crawl]

Cancel a running crawl with `cancel_crawl`.

```ruby
result = client.cancel_crawl(response.id)
puts result
```

### Mapping a Website [#mapping-a-website]

Discover links on a site using `map`.

```ruby
data = client.map(
  "https://firecrawl.dev",
  Firecrawl::Models::MapOptions.new(
    limit: 100,
    search: "blog"
  )
)

data.links&.each do |link|
  puts "#{link["url"]} - #{link["title"]}"
end
```

### Searching the Web [#searching-the-web]

Search with optional settings using `search`.

```ruby
results = client.search(
  "firecrawl web scraping",
  Firecrawl::Models::SearchOptions.new(limit: 10)
)

results.web&.each do |result|
  puts "#{result["title"]} - #{result["url"]}"
end
```

### Batch Scraping [#batch-scraping]

Scrape multiple URLs in parallel using `batch_scrape`.

```ruby
job = client.batch_scrape(
  ["https://firecrawl.dev", "https://firecrawl.dev/blog"],
  Firecrawl::Models::BatchScrapeOptions.new(
    options: Firecrawl::Models::ScrapeOptions.new(
      formats: ["markdown"]
    )
  )
)

job.data&.each do |doc|
  puts doc.markdown
end
```

### Agent [#agent]

Run an AI-powered agent with `agent`.

```ruby
result = client.agent(
  Firecrawl::Models::AgentOptions.new(
    prompt: "Find the pricing plans for Firecrawl and compare them"
  )
)

puts result.data
```

With a JSON schema for structured output:

```ruby
result = client.agent(
  Firecrawl::Models::AgentOptions.new(
    prompt: "Extract pricing plan details",
    urls: ["https://firecrawl.dev"],
    schema: {
      "type" => "object",
      "properties" => {
        "plans" => {
          "type" => "array",
          "items" => {
            "type" => "object",
            "properties" => {
              "name" => { "type" => "string" },
              "price" => { "type" => "string" }
            }
          }
        }
      }
    }
  )
)

puts result.data
```

### Usage & Metrics [#usage--metrics]

Check concurrency and remaining credits:

```ruby
concurrency = client.get_concurrency
puts "Concurrency: #{concurrency.concurrency}/#{concurrency.max_concurrency}"

credits = client.get_credit_usage
puts "Remaining credits: #{credits.remaining_credits}"
```

## Browser [#browser]

The Ruby SDK includes Browser Sandbox helpers.

### Scrape-Bound Interactive Session [#scrape-bound-interactive-session]

Use a scrape job ID to run follow-up browser code in the same replayed context:

* `interact(...)` runs code in the scrape-bound browser session (and initializes it on first use).
* `stop_interactive_browser(...)` explicitly stops the interactive session when you are done.

```ruby
scrape_job_id = "550e8400-e29b-41d4-a716-446655440000"

run = client.interact(
  scrape_job_id,
  "console.log(page.url());",
  language: "node",
  timeout: 60
)

puts run["stdout"]

deleted = client.stop_interactive_browser(scrape_job_id)
puts "Deleted: #{deleted["success"]}"
```

## Configuration [#configuration]

`Firecrawl::Client.new` supports the following options:

| Option           | Type      | Default                                              | Description                              |
| ---------------- | --------- | ---------------------------------------------------- | ---------------------------------------- |
| `api_key`        | `String`  | `FIRECRAWL_API_KEY` env var                          | Your Firecrawl API key                   |
| `api_url`        | `String`  | `https://api.firecrawl.dev` (or `FIRECRAWL_API_URL`) | API base URL                             |
| `timeout`        | `Integer` | `300`                                                | HTTP request timeout in seconds          |
| `max_retries`    | `Integer` | `3`                                                  | Automatic retries for transient failures |
| `backoff_factor` | `Float`   | `0.5`                                                | Exponential backoff factor in seconds    |

```ruby
client = Firecrawl::Client.new(
  api_key: "fc-your-api-key",
  api_url: "https://api.firecrawl.dev",
  timeout: 300,
  max_retries: 3,
  backoff_factor: 0.5
)
```

## Error Handling [#error-handling]

The SDK raises exceptions under the `Firecrawl` module.

```ruby
begin
  doc = client.scrape("https://example.com")
rescue Firecrawl::AuthenticationError => e
  puts "Auth failed: #{e.message}"
rescue Firecrawl::RateLimitError => e
  puts "Rate limited: #{e.message}"
rescue Firecrawl::JobTimeoutError => e
  puts "Job #{e.job_id} timed out after #{e.timeout_seconds}s"
rescue Firecrawl::FirecrawlError => e
  puts "Error (#{e.status_code}): #{e.message}"
end
```
