# Firecrawl

Auto-generated Elixir client for the [Firecrawl API v2](https://docs.firecrawl.dev/api-reference).

Built with [`Req`](https://hexdocs.pm/req) — minimal, idiomatic, auto-generated from the OpenAPI spec with [`NimbleOptions`](https://hexdocs.pm/nimble_options) validation.

## Installation

Add `firecrawl` to your list of dependencies in `mix.exs`:

```elixir
def deps do
  [
    {:firecrawl, "~> 0.1.0"}
  ]
end
```

## Configuration

Set your API key in application config:

```elixir
config :firecrawl, api_key: "fc-your-api-key"
```

Or pass it as an option to any function:

```elixir
Firecrawl.scrape_and_extract_from_url([url: "https://example.com"], api_key: "fc-your-api-key")
```

If no API key is found in config or options, a `RuntimeError` is raised with instructions.

## Usage

All params are passed as keyword lists with snake_case keys. Invalid keys, missing required params, and type errors are caught immediately by `NimbleOptions`.

```elixir
# Scrape a URL
{:ok, response} = Firecrawl.scrape_and_extract_from_url(
  url: "https://example.com",
  formats: ["markdown"]
)

# Crawl a site
{:ok, response} = Firecrawl.crawl_urls(
  url: "https://example.com",
  limit: 100,
  sitemap: :skip
)

# Map URLs
{:ok, response} = Firecrawl.map_urls(url: "https://example.com")

# Search
{:ok, response} = Firecrawl.search_and_scrape(query: "firecrawl web scraping")

# Extract structured data
{:ok, response} = Firecrawl.extract_data(
  urls: ["https://example.com"],
  prompt: "Extract the main heading and description"
)

# Check crawl status
{:ok, response} = Firecrawl.get_crawl_status("job-uuid")

# Self-hosted instance
{:ok, response} = Firecrawl.scrape_and_extract_from_url(
  [url: "https://example.com"],
  base_url: "https://your-instance.com/v2"
)
```

### Bang variants

Every function has a `!` variant that raises on error instead of returning `{:error, _}`:

```elixir
response = Firecrawl.scrape_and_extract_from_url!(url: "https://example.com")
```

## Regenerating from the OpenAPI Spec

The entire client is auto-generated from the Firecrawl OpenAPI specification. To regenerate after spec changes:

```bash
mix run generate.exs
```

This will:

1. Fetch the latest OpenAPI JSON from GitHub
2. Generate all API wrapper functions in `lib/firecrawl.ex`
3. Bump the patch version in `mix.exs` (only if the generated code changed)

Re-running when nothing changed is a no-op — the version is not bumped.
