Research and Server

Purpose

Agent browser engine for fetch, parse, search, perceive, research, protocol routing, and HTTP serving.

This page follows the real source shape for Weave Browser Engine and explains the workflow a developer is likely to use first.

Developer workflow

Start from the smallest constructor or builder, perform one meaningful operation, inspect the returned state, then add the relevant policy, storage, or network integration. The examples below should be expanded whenever the crate API changes.

Example shape

use weave_browser_engine::research::{research, ResearchConfig};
use weave_browser_engine::serve;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    // ResearchConfig fluently composes the deep-research pipeline: pick a
    // depth, source cap, verification toggle, and search backend.
    let config = ResearchConfig::new("Weave Strand replication")
        .depth(2)
        .max_sources(6)
        .verify(true)
        .engine("duckduckgo");

    let report = research(&config).await?;
    println!(
        "topic={} sources={} synthesis_chars={}",
        report["topic"].as_str().unwrap_or(""),
        report["sources"].as_array().map(|a| a.len()).unwrap_or(0),
        report["synthesis"].as_str().map(str::len).unwrap_or(0),
    );

    // Spawn the axum API surface that wraps fetch/search/perceive/research.
    tokio::spawn(async move { let _ = serve::serve("127.0.0.1:0").await; });
    Ok(())
