Rust SDK | EvoCrawl

Installation

The official Rust SDK is maintained in the EvoCrawl monorepo at apps/rust-sdk. To install the EvoCrawl Rust SDK, add the dependency from crates.io:

[dependencies]
evocrawl = "2"
tokio = { version = "1", features = ["full"] }
serde_json = "1"

Or install via Cargo:

cargo add evocrawl
cargo add tokio --features full
cargo add serde_json

Requires Rust 1.70 or later.

Usage

Get an API key from evocrawl.com
Set the API key as an environment variable named EVOCRAWL_API_KEY, or pass it directly to Client::new(...)

Here is a quick example using the SDK:

use evocrawl::{Client, CrawlOptions, ScrapeOptions, Format};

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let client = Client::new("fc-YOUR-API-KEY")?;

    let doc = client.scrape(
        "https://evocrawl.com",
        ScrapeOptions {
            formats: Some(vec![Format::Markdown]),
            ..Default::default()
        },
    ).await?;

    let job = client.crawl(
        "https://evocrawl.com",
        CrawlOptions {
            limit: Some(5),
            ..Default::default()
        },
    ).await?;

    println!("{}", doc.markdown.unwrap_or_default());
    println!("Crawled pages: {}", job.data.len());
    Ok(())
}

Scraping a URL

To scrape a single URL, use the scrape method.

use evocrawl::{Client, ScrapeOptions, Format};

let doc = client.scrape(
    "https://evocrawl.com",
    ScrapeOptions {
        formats: Some(vec![Format::Markdown, Format::Html]),
        only_main_content: Some(true),
        wait_for: Some(5000),
        ..Default::default()
    },
).await?;

println!("{}", doc.markdown.unwrap_or_default());
if let Some(meta) = &doc.metadata {
    println!("{:?}", meta.title);
}

JSON Extraction

Extract structured JSON using scrape_with_schema:

use evocrawl::Client;
use serde_json::json;

let schema = json!({
    "type": "object",
    "properties": {
        "name": { "type": "string" },
        "price": { "type": "number" }
    }
});

let data = client.scrape_with_schema(
    "https://example.com/product",
    schema,
    Some("Extract the product name and price"),
).await?;

println!("{}", serde_json::to_string_pretty(&data)?);

Or configure JSON extraction via ScrapeOptions directly:

use evocrawl::{Client, ScrapeOptions, Format, JsonOptions};
use serde_json::json;

let doc = client.scrape(
    "https://example.com/product",
    ScrapeOptions {
        formats: Some(vec![Format::Json]),
        json_options: Some(JsonOptions {
            schema: Some(json!({
                "type": "object",
                "properties": {
                    "name": { "type": "string" },
                    "price": { "type": "number" }
                }
            })),
            prompt: Some("Extract the product name and price".to_string()),
            ..Default::default()
        }),
        ..Default::default()
    },
).await?;

println!("{:?}", doc.json);

Crawling a Website

To crawl a website and wait for completion, use crawl.

use evocrawl::{Client, CrawlOptions, ScrapeOptions, Format};

let job = client.crawl(
    "https://evocrawl.com",
    CrawlOptions {
        limit: Some(50),
        max_discovery_depth: Some(3),
        scrape_options: Some(ScrapeOptions {
            formats: Some(vec![Format::Markdown]),
            ..Default::default()
        }),
        ..Default::default()
    },
).await?;

println!("Status: {:?}", job.status);
println!("Progress: {}/{}", job.completed, job.total);

for page in &job.data {
    if let Some(meta) = &page.metadata {
        println!("{:?}", meta.source_url);
    }
}

Start a Crawl

Start a job without waiting using start_crawl.

use evocrawl::{Client, CrawlOptions};

let start = client.start_crawl(
    "https://evocrawl.com",
    CrawlOptions {
        limit: Some(100),
        ..Default::default()
    },
).await?;

println!("Job ID: {}", start.id);

Checking Crawl Status

Check crawl progress with get_crawl_status.

let status = client.get_crawl_status(&start.id).await?;
println!("Status: {:?}", status.status);
println!("Progress: {}/{}", status.completed, status.total);

Cancelling a Crawl

Cancel a running crawl with cancel_crawl.

let result = client.cancel_crawl(&start.id).await?;
println!("{:?}", result);

Checking Crawl Errors

Retrieve errors from a crawl job with get_crawl_errors.

let errors = client.get_crawl_errors(&start.id).await?;
println!("{:?}", errors);

Mapping a Website

Discover links on a site using map.

use evocrawl::{Client, MapOptions};

let response = client.map(
    "https://evocrawl.com",
    MapOptions {
        limit: Some(100),
        search: Some("blog".to_string()),
        ..Default::default()
    },
).await?;

for link in &response.links {
    println!("{} - {}", link.url, link.title.as_deref().unwrap_or(""));
}

For a simpler result with just URLs, use map_urls:

let urls = client.map_urls("https://evocrawl.com", None).await?;
for url in &urls {
    println!("{}", url);
}

Searching the Web

Search with optional settings using search.

use evocrawl::{Client, SearchOptions};

let results = client.search(
    "evocrawl web scraping",
    SearchOptions {
        limit: Some(10),
        ..Default::default()
    },
).await?;

if let Some(web) = results.data.web {
    for item in web {
        match item {
            evocrawl::SearchResultOrDocument::WebResult(r) => {
                println!("{} - {}", r.url, r.title.unwrap_or_default());
            }
            evocrawl::SearchResultOrDocument::Document(d) => {
                println!("{}", d.markdown.unwrap_or_default());
            }
        }
    }
}

For a convenience method that returns scraped documents directly:

let docs = client.search_and_scrape("evocrawl web scraping", 5).await?;
for doc in &docs {
    println!("{}", doc.markdown.as_deref().unwrap_or(""));
}

Batch Scraping

Scrape multiple URLs in parallel using batch_scrape.

use evocrawl::{Client, BatchScrapeOptions, ScrapeOptions, Format};

let urls = vec![
    "https://evocrawl.com".to_string(),
    "https://evocrawl.com/blog".to_string(),
];

let job = client.batch_scrape(
    urls,
    BatchScrapeOptions {
        options: Some(ScrapeOptions {
            formats: Some(vec![Format::Markdown]),
            ..Default::default()
        }),
        ..Default::default()
    },
).await?;

for doc in &job.data {
    println!("{}", doc.markdown.as_deref().unwrap_or(""));
}

Agent

Run an AI-powered agent with agent.

use evocrawl::{Client, AgentOptions};

let result = client.agent(
    AgentOptions {
        prompt: "Find the pricing plans for EvoCrawl and compare them".to_string(),
        ..Default::default()
    },
).await?;

println!("{:?}", result.data);

With a JSON schema for structured output:

use evocrawl::{Client, AgentOptions, AgentModel};
use serde::Deserialize;
use serde_json::json;

#[derive(Debug, Deserialize)]
struct PricingPlan {
    name: String,
    price: String,
}

#[derive(Debug, Deserialize)]
struct PricingData {
    plans: Vec<PricingPlan>,
}

let schema = json!({
    "type": "object",
    "properties": {
        "plans": {
            "type": "array",
            "items": {
                "type": "object",
                "properties": {
                    "name": { "type": "string" },
                    "price": { "type": "string" }
                }
            }
        }
    }
});

let result: Option<PricingData> = client.agent_with_schema(
    vec!["https://evocrawl.com".to_string()],
    "Extract pricing plan details",
    schema,
).await?;

if let Some(data) = result {
    for plan in &data.plans {
        println!("{}: {}", plan.name, plan.price);
    }
}

Scrape-Bound Interactive Session

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

interact(...) runs code or prompts in the scrape-bound browser session.
stop_interaction(...) stops the interactive session when you are done.

use evocrawl::{Client, ScrapeExecuteOptions, ScrapeExecuteLanguage};

let scrape_job_id = "550e8400-e29b-41d4-a716-446655440000";

// Run code in the browser session
let run = client.interact(
    scrape_job_id,
    ScrapeExecuteOptions {
        code: Some("console.log(await page.title())".to_string()),
        language: Some(ScrapeExecuteLanguage::Node),
        timeout: Some(60),
        ..Default::default()
    },
).await?;

println!("{:?}", run.stdout);

// Or use a natural language prompt
let run = client.interact(
    scrape_job_id,
    ScrapeExecuteOptions {
        prompt: Some("Click the pricing tab and summarize the plans".to_string()),
        ..Default::default()
    },
).await?;

// Stop the session when done
client.stop_interaction(scrape_job_id).await?;

Configuration

Client::new(...) and Client::new_selfhosted(...) create the client.

Option	Description
`Client::new(api_key)`	Create a client for the EvoCrawl cloud service (`https://api.evocrawl.com`)
`Client::new_selfhosted(api_url, api_key)`	Create a client for a self-hosted EvoCrawl instance

use evocrawl::Client;

// Cloud service
let client = Client::new("fc-your-api-key")?;

// Self-hosted
let client = Client::new_selfhosted(
    "http://localhost:3002",
    Some("fc-your-api-key"),
)?;

// Self-hosted without authentication
let client = Client::new_selfhosted(
    "http://localhost:3002",
    None::<&str>,
)?;

Environment Variable

Set the EVOCRAWL_API_KEY environment variable instead of passing the key directly:

export EVOCRAWL_API_KEY=fc-YOUR-API-KEY

let api_key = std::env::var("EVOCRAWL_API_KEY")
    .expect("EVOCRAWL_API_KEY must be set");
let client = Client::new(api_key)?;

Poll Intervals

Synchronous methods (crawl, batch_scrape, agent) poll until completion. You can customize the poll interval via the options struct:

use evocrawl::CrawlOptions;

let options = CrawlOptions {
    limit: Some(50),
    poll_interval: Some(3000), // Poll every 3 seconds (default: 2000ms)
    ..Default::default()
};

Error Handling

The SDK uses the EvocrawlError enum, which implements Error, Debug, and Display. All methods return Result<T, EvocrawlError>.

use evocrawl::{Client, EvocrawlError};

match client.scrape("https://example.com", None).await {
    Ok(doc) => println!("{}", doc.markdown.unwrap_or_default()),
    Err(EvocrawlError::HttpRequestFailed(action, status, msg)) => {
        eprintln!("HTTP {}: {} ({})", status, msg, action);
    }
    Err(EvocrawlError::APIError(action, api_err)) => {
        eprintln!("API error ({}): {}", action, api_err.error);
    }
    Err(EvocrawlError::JobFailed(msg)) => {
        eprintln!("Job failed: {}", msg);
    }
    Err(EvocrawlError::Misuse(msg)) => {
        eprintln!("SDK misuse: {}", msg);
    }
    Err(e) => eprintln!("Error: {}", e),
}
