The Firecrawl API gives you programmatic access to web data. All endpoints share a common base URL, authentication scheme, and response format described on this page.
## Features [#features]
Extract content from any webpage in markdown or json format.
Upload files and parse them into markdown or other formats.
Crawl entire websites and get content from all pages.
Get a complete list of URLs from any website quickly and reliably.
Search the web and get full page content in any format.
## Agentic Features [#agentic-features]
Autonomous web data gathering powered by AI.
Create and control browser sessions for interactive web tasks.
## Base URL [#base-url]
All requests use the following base URL:
```bash
https://api.firecrawl.dev
```
## Authentication [#authentication]
Every request requires an `Authorization` header with your API key:
```bash
Authorization: Bearer fc-YOUR-API-KEY
```
Include this header in all API calls. You can find your API key in the [Firecrawl dashboard](https://www.firecrawl.dev/app/api-keys).
If you are an agent without an API key, start with [Get credentials](/ai-onboarding#get-credentials). If your platform supports WorkOS ID-JAG, use [`auth.md`](https://www.firecrawl.dev/auth.md) for registration instructions.

-H "Content-Type: application/json" \
-d '{"url": "https://example.com"}'
```
```python
from firecrawl import Firecrawl
firecrawl = Firecrawl(api_key="fc-YOUR-API-KEY")
result = firecrawl.scrape("https://example.com")
```
```js
import { Firecrawl } from 'firecrawl';
const firecrawl = new Firecrawl({ apiKey: "fc-YOUR-API-KEY" });
const result = await firecrawl.scrape('https://example.com');
```
## Response codes [#response-codes]
Firecrawl uses conventional HTTP status codes to indicate the outcome of your requests. Codes in the `2xx` range indicate success, `4xx` codes indicate client errors, and `5xx` codes indicate server errors.
See [Errors](/api-reference/errors) for the full reference, including the `error` string returned for each failure mode, retry guidance, and a copy-pasteable backoff snippet.
## 429 responses [#429-responses]
When you exceed your plan's rate or concurrency limits, the API returns a `429` status code. See [Rate Limits](/rate-limits) for per-plan limits and [Errors](/api-reference/errors) for retry guidance.
