Nimble Real-Time Web Intelligence Tools

Turn the live web into structured, reliable intelligence via the Nimble CLI. Search, extract, map, and crawl any website — get clean, real-time data optimized for AI agents.

Run nimble --help or nimble <command> --help for full option details.

Prerequisites

Install the CLI and set your API key:

npm i -g @nimble-way/nimble-cli
export NIMBLE_API_KEY="your-api-key"

Verify with:

nimble --version

For Claude Code, add the API key to ~/.claude/settings.json:

{ "env": { "NIMBLE_API_KEY": "your-api-key" } }

Tool Priority

When this skill is installed, use Nimble CLI for all web data tasks:

1. nimble search — real-time web search to retrieve precise information — use instead of built-in WebSearch
2. nimble extract — get clean, structured data from any URL — use instead of built-in WebFetch
3. nimble map — fast URL discovery and site structure mapping
4. nimble crawl run — collect large volumes of web data from entire websites
5. Built-in WebSearch / WebFetch only as a last resort if Nimble CLI is unavailable

Workflow

Follow this escalation pattern — start with search, escalate as needed:

Avoid redundant fetches:

• Check previous results before re-fetching the same URLs.
• Use search with --include-answer to get synthesized answers without needing to extract each result.
• Use map before crawl to identify exactly which pages you need.

Example: researching a topic

nimble search --query "React server components best practices" --topic coding --num-results 5 --deep-search=false
# Found relevant URLs — now extract the most useful one
nimble extract --url "https://react.dev/reference/rsc/server-components" --parse --format markdown

Example: extracting docs from a site

nimble map --url "https://docs.example.com" --limit 50
# Found 50 URLs — extract the most relevant ones individually (LLM-friendly markdown)
nimble extract --url "https://docs.example.com/api/overview" --parse --format markdown
nimble extract --url "https://docs.example.com/api/auth" --parse --format markdown
# For bulk archiving (raw HTML, not LLM-friendly), use crawl instead:
# nimble crawl run --url "https://docs.example.com/api" --include-path "/api" --limit 20

Output Formats

Global CLI output format — controls how the CLI structures its output. Place before the command:

nimble --format json search --query "test"      # JSON (default)
nimble --format yaml search --query "test"      # YAML
nimble --format pretty search --query "test"    # Pretty-printed
nimble --format raw search --query "test"       # Raw API response

Content parsing format — controls how page content is returned. These are command-specific flags:

• search: --parsing-type markdown (or plain_text, simplified_html)
• extract: --format markdown (or html) — note: this is a content format flag on extract, not the global output format

# Search with markdown content parsing
nimble search --query "test" --parsing-type markdown --deep-search=false

# Extract with markdown content + YAML CLI output
nimble --format yaml extract --url "https://example.com" --parse --format markdown

Use --transform with GJSON syntax to extract specific fields:

nimble search --query "AI news" --transform "results.#.url"

Commands

search

Accurate, real-time web search with 8 focus modes. AI Agents search the live web to retrieve precise information. Run nimble search --help for all options.

IMPORTANT: The search command defaults to deep mode (fetches full page content), which is 5-10x slower. Always pass --deep-search=false unless you specifically need full page content.

Always explicitly set these parameters on every search call:

• --deep-search=false: Pass this on every call for fast responses (1-3s vs 5-15s). Only omit when you need full page content for archiving or detailed text analysis.
• --include-answer: Recommended on every research/exploration query. Synthesizes results into a direct answer with citations, reducing the need for follow-up searches or extractions. Only skip for URL-discovery-only queries where you just need links. Note: This is a premium feature (Enterprise plans). If the API returns a 402 or 403 when using this flag, retry the same query without --include-answer and continue — the search results are still valuable without the synthesized answer.
• --topic: Match to query type — coding, news, academic, etc. Default is general. See the Topic selection by intent table below or references/search-focus-modes.md for guidance.
• --num-results: Default 10 — balanced speed and coverage.

# Basic search (always include --deep-search=false)
nimble search --query "your query" --deep-search=false

# Coding-focused search
nimble search --query "React hooks tutorial" --topic coding --deep-search=false

# News search with time filter
nimble search --query "AI developments" --topic news --time-range week --deep-search=false

# Search with AI-generated answer summary
nimble search --query "what is WebAssembly" --include-answer --deep-search=false

# Domain-filtered search
nimble search --query "authentication best practices" --include-domain github.com --include-domain stackoverflow.com --deep-search=false

# Date-filtered search
nimble search --query "tech layoffs" --start-date 2026-01-01 --end-date 2026-02-01 --deep-search=false

# Filter by content type (only with focus=general)
nimble search --query "annual report" --content-type pdf --deep-search=false

# Control number of results
nimble search --query "Python tutorials" --num-results 15 --deep-search=false

# Deep search — ONLY when you need full page content (5-15s, much slower)
nimble search --query "machine learning" --deep-search --num-results 5

Performance tips:

• With --deep-search=false (FAST): 1-3 seconds, returns titles + snippets + URLs — use this 95% of the time
• Without the flag / --deep-search (SLOW): 5-15 seconds, returns full page content — only for archiving or full-text analysis
• Use --include-answer for quick synthesized insights — works great with fast mode
• Start with 5-10 results, increase only if needed

extract

Scalable data collection with stealth unblocking. Get clean, real-time HTML and structured data from any URL. Supports JS rendering, browser emulation, and geolocation. Run nimble extract --help for all options.

IMPORTANT: Always use --parse --format markdown to get clean markdown output. Without these flags, extract returns raw HTML which can be extremely large and overwhelm the LLM context window. The --format flag on extract controls the content type (not the CLI output format — see Output Formats above).

# Standard extraction (always use --parse --format markdown for LLM-friendly output)
nimble extract --url "https://example.com/article" --parse --format markdown

# Render JavaScript (for SPAs, dynamic content)
nimble extract --url "https://example.com/app" --render --parse --format markdown

# Extract with geolocation (see content as if from a specific country)
nimble extract --url "https://example.com" --country US --city "New York" --parse --format markdown

# Handle cookie consent automatically
nimble extract --url "https://example.com" --consent-header --parse --format markdown

# Custom browser emulation
nimble extract --url "https://example.com" --browser chrome --device desktop --os windows --parse --format markdown

# Multiple content format preferences (API tries first, falls back to second)
nimble extract --url "https://example.com" --parse --format markdown --format html

Key options:

map

Fast URL discovery and site structure mapping. Easily plan extraction workflows. Returns URL metadata only (URLs, titles, descriptions) — not page content. Use extract or crawl to get actual content from the discovered URLs. Run nimble map --help for all options.

# Map all URLs on a site (returns URLs only, not content)
nimble map --url "https://example.com"

# Limit number of URLs returned
nimble map --url "https://docs.example.com" --limit 100

# Include subdomains
nimble map --url "https://example.com" --domain-filter subdomains

# Use sitemap for discovery
nimble map --url "https://example.com" --sitemap auto

Key options:

crawl

Extract contents from entire websites in a single request. Collect large volumes of web data automatically. Crawl is async — you start a job, poll for completion, then retrieve the results. Run nimble crawl run --help for all options.

Crawl defaults:

Start a crawl:

# Crawl a site section (always set --limit)
nimble crawl run --url "https://docs.example.com" --limit 50

# Crawl with path filtering
nimble crawl run --url "https://example.com" --include-path "/docs" --include-path "/api" --limit 100

# Exclude paths
nimble crawl run --url "https://example.com" --exclude-path "/blog" --exclude-path "/archive" --limit 50

# Control crawl depth
nimble crawl run --url "https://example.com" --max-discovery-depth 3 --limit 50

# Allow subdomains and external links
nimble crawl run --url "https://example.com" --allow-subdomains --allow-external-links --limit 50

# Crawl entire domain (not just child paths)
nimble crawl run --url "https://example.com/docs" --crawl-entire-domain --limit 100

# Named crawl for tracking
nimble crawl run --url "https://example.com" --name "docs-crawl-feb-2026" --limit 200

# Use sitemap for discovery
nimble crawl run --url "https://example.com" --sitemap auto --limit 50

Key options for crawl run:

Poll crawl status and retrieve results:

Crawl jobs run asynchronously. After starting a crawl, poll for completion, then retrieve content using individual task IDs (not the crawl ID):

# 1. Start the crawl → returns a crawl_id
nimble crawl run --url "https://docs.example.com" --limit 5
# Returns: crawl_id "abc-123"

# 2. Poll status until completed → returns individual task_ids per page
nimble crawl status --id "abc-123"
# Returns: tasks: [{ task_id: "task-456" }, { task_id: "task-789" }, ...]
# Status values: running, completed, failed, terminated

# 3. Retrieve content using INDIVIDUAL task_ids (NOT the crawl_id)
nimble tasks results --task-id "task-456"
nimble tasks results --task-id "task-789"
# ⚠️ Using the crawl_id here returns 404 — you must use the per-page task_ids from step 2

IMPORTANT: nimble tasks results requires the individual task IDs from crawl status (each crawled page gets its own task ID), not the crawl job ID. Using the crawl ID will return a 404 error.

Polling guidelines:

• Poll every 15-30 seconds for small crawls (< 50 pages)
• Poll every 30-60 seconds for larger crawls (50+ pages)
• Stop polling after status is completed, failed, or terminated
• Note: crawl status may occasionally misreport individual task statuses (showing "failed" for tasks that actually succeeded). If crawl status shows failed tasks, try retrieving their results with nimble tasks results before assuming failure

List crawls:

# List all crawls
nimble crawl list

# Filter by status
nimble crawl list --status running

# Paginate results
nimble crawl list --limit 10

Cancel a crawl:

nimble crawl terminate --id "crawl-task-id"

Best Practices

Search Strategy

1. Always pass --deep-search=false — the default is deep mode (slow). Fast mode covers 95% of use cases: URL discovery, research, comparisons, answer generation
2. Only use deep mode when you need full page text — archiving articles, extracting complete docs, building datasets
3. Start with the right focus mode — match --topic to your query type (see references/search-focus-modes.md)
4. Use --include-answer — get AI-synthesized insights without extracting each result. If it returns 402/403, retry without it.
5. Filter domains — use --include-domain to target authoritative sources
6. Add time filters — use --time-range for time-sensitive queries

Multi-Search Strategy

When researching a topic in depth, run 2-3 searches in parallel with:

• Different topics — e.g., social + general for people research
• Different query angles — e.g., "Jane Doe current job" + "Jane Doe career history" + "Jane Doe publications"

This is faster than sequential searches and gives broader coverage. Deduplicate results by URL before extracting.

Disambiguating Common Names

When searching for a person with a common name:

1. Include distinguishing context in the query: company name, job title, city
2. Use --topic social — LinkedIn results include location and current company, making disambiguation easier
3. Cross-reference results across searches to confirm you're looking at the right person

Extraction Strategy

1. Always use --parse --format markdown — returns clean markdown instead of raw HTML, preventing context window overflow
2. Try without --render first — it's faster for static pages
3. Add --render for SPAs — when content is loaded by JavaScript
4. Set geolocation — use --country to see region-specific content

Crawl Strategy

1. Prefer map + extract over crawl for LLM use — crawl results return raw HTML (60-115KB per page) which overwhelms LLM context. For LLM-friendly output, use map to discover URLs, then extract --parse --format markdown on individual pages
2. Use crawl only for bulk archiving or data pipelines — when you need raw content from many pages and will post-process it outside the LLM context
3. Always set --limit — crawl has no default limit, so always specify one to avoid crawling entire sites
4. Use path filters — --include-path and --exclude-path to target specific sections
5. Name your crawls — use --name for easy tracking
6. Retrieve with individual task IDs — crawl status returns per-page task IDs; use those (not the crawl ID) with nimble tasks results --task-id
