title: Web Module description: Fetch and process web content. Converts HTML to Markdown, optionally summarizes against a prompt via the configured LLM provider, with URL validation, same-origin redirect handling, LRU caching, and a preapproved-host allowlist.

@loopstack/web-module

Installation

npm install @loopstack/web-module

Register the module in your app module:

import { Module } from '@nestjs/common';
import { ClaudeModule } from '@loopstack/claude-module';
import { LlmProviderModule } from '@loopstack/llm-provider-module';
import { WebModule } from '@loopstack/web-module';

@Module({
  imports: [LlmProviderModule, ClaudeModule, WebModule],
})
export class AppModule {}

The optional summarization step (triggered when a prompt arg is passed to the tool) runs through the LLM provider layer: the tool's provider arg, else the LlmProviderModule default provider, else claude. The model is the tool's model arg, else CLAUDE_WEB_FETCH_MODEL, else claude-haiku-4-5-20251001 — pass model when summarizing with a provider other than claude. The step needs that provider's API key:

ANTHROPIC_API_KEY=sk-ant-...

A summarized result returns the provider, model and token usage as LlmResultMeta metadata, which @loopstack/quota charges to the llm-cost quota.
