# Web tools
|
||
|
||
Clawdbot ships two lightweight web tools:
|
||
|
||
- `web_search` — Brave Search API queries (fast, structured results).
|
||
- `web_fetch` — HTTP fetch + readable extraction (HTML → markdown/text).
|
||
|
||
These are **not** browser automation. For JS-heavy sites or logins, use the
|
||
[Browser tool](/tools/browser).
|
||
|
||
## How it works
|
||
|
||
- `web_search` calls Brave’s Search API and returns structured results
|
||
(title, URL, snippet). No browser is involved.
|
||
- Results are cached by query for 15 minutes (configurable).
|
||
- `web_fetch` does a plain HTTP GET and extracts readable content
|
||
(HTML → markdown/text). It does **not** execute JavaScript.
|
||
- In sandboxed sessions, `web_fetch` is enabled automatically (unless explicitly disabled).
|
||
|
||
## web_search
|
||
|
||
Search the web with Brave’s API.
|
||
|
||
### Requirements
|
||
|
||
- `tools.web.search.enabled: true`
|
||
- Brave API key via `BRAVE_API_KEY` **or** `tools.web.search.apiKey`
|
||
|
||
### Config
|
||
|
||
```json5
|
||
{
|
||
tools: {
|
||
web: {
|
||
search: {
|
||
enabled: true,
|
||
apiKey: "BRAVE_API_KEY_HERE", // optional if BRAVE_API_KEY is set
|
||
maxResults: 5,
|
||
timeoutSeconds: 30,
|
||
cacheTtlMinutes: 15
|
||
}
|
||
}
|
||
}
|
||
}
|
||
```
|
||
|
||
### Tool parameters
|
||
|
||
- `query` (required)
|
||
- `count` (1–10; default from config)
|
||
|
||
## web_fetch
|
||
|
||
Fetch a URL and extract readable content.
|
||
|
||
### Requirements
|
||
|
||
- `tools.web.fetch.enabled: true`
|
||
|
||
### Config
|
||
|
||
```json5
|
||
{
|
||
tools: {
|
||
web: {
|
||
fetch: {
|
||
enabled: true,
|
||
maxChars: 50000,
|
||
timeoutSeconds: 30,
|
||
cacheTtlMinutes: 15,
|
||
userAgent: "clawdbot/2026.1.14"
|
||
}
|
||
}
|
||
}
|
||
}
|
||
```
|
||
|
||
### Tool parameters
|
||
|
||
- `url` (required, http/https only)
|
||
- `extractMode` (`markdown` | `text`)
|
||
- `maxChars` (truncate long pages)
|
||
|
||
Notes:
|
||
- `web_fetch` is best-effort extraction; some sites will need the browser tool.
|
||
- Responses are cached (default 15 minutes) to reduce repeated fetches.
|
||
- If you use tool profiles/allowlists, add `web_search`/`web_fetch` or `group:web`.
|
||
|
||
## Getting a Brave API key
|
||
|
||
1) Create a Brave Search API account at https://brave.com/search/api/
|
||
2) Generate an API key in the dashboard.
|
||
3) Set `BRAVE_API_KEY` in your environment or paste it into `tools.web.search.apiKey`.
|
||
|
||
Brave provides a free tier plus paid plans; check the Brave API portal for the
|
||
current limits and pricing.
