Zero Api Key Web Search

OpenClaw skill for source-backed web search, page reading, and evidence-aware claim checking. No API keys required by default; optional providers can be enabled for stronger coverage. v23: multi-engine SERP (7 engines), Web Unlocker for blocked pages, auto-fallback on 403/429.

Zero-API-Key Web Search for OpenClaw

This skill gives OpenClaw a practical verification workflow:

• zero-search for live search results (7 engines via Bright Data)
• zero-search providers for provider discovery
• zero-browse for reading pages (auto-unlocks blocked content)
• zero-verify for support/conflict classification
• zero-report for a citation-ready summary with next steps
• zero-setup for interactive provider configuration

Install

bash

pip install zero-api-key-web-search

Minimum verification

bash

zero-search "OpenAI API pricing" --type news --timelimit w
zero-search providers
zero-browse "https://docs.python.org/3/whatsnew/"
zero-verify "Python 3.13 is the latest stable release" --deep --max-pages 2 --json
zero-report "Python 3.13 stable release" --claim "Python 3.13 is the latest stable release" --deep --json

Provider paths

Profile	Providers	Best for
free	ddgs	Zero-setup local search
free-verified	ddgs, searxng	Free cross-validation
production	brightdata	Production reliability and geo-targeting
production-unlock	brightdata, web_unlocker	Production SERP + blocked page access
max-evidence	ddgs, searxng, brightdata	Maximum provider diversity

Recommended flow

1. Run zero-search for factual or recent questions.
2. Use zero-browse on the most relevant source when snippets are not enough.
3. Use zero-verify when a concrete claim needs a support/conflict summary.
4. Use zero-report when you want a compact evidence package with citations and next steps.
5. Use --deep when the claim matters enough to justify page-aware verification.
6. Cite the returned URLs in the final answer.
7. Use optional brightdata only when configured or explicitly requested.

Multi-engine search (Bright Data)

bash

zero-search "AI regulation" --provider brightdata --engine google --region us-en --json
zero-search "AI regulation" --provider brightdata --engine bing --region gb-en --json
zero-search "news" --provider brightdata --engine yandex --region ru-ru --json

Supported engines: google, bing, duckduckgo, yandex, baidu, yahoo, naver.

Web Unlocker (blocked pages)

bash

# Auto-fallback (default) — direct fetch, then unlocker on 403/429
zero-browse "https://protected-site.com/article"

# Force Web Unlocker
zero-browse "https://protected-site.com/article" --use-unlocker always

Optional Bright Data provider

bash

# Interactive setup wizard
zero-setup

# Or set environment variables
export ZERO_SEARCH_BRIGHTDATA_API_KEY="..."
export ZERO_SEARCH_BRIGHTDATA_ZONE="serp_api1"
export ZERO_SEARCH_BRIGHTDATA_UNLOCKER_ZONE="web_unlocker1"

What success looks like

• the verdict is explicit
• the result includes support and conflict scores
• page_aware is true when deep verification ran
• the recommended free path is ddgs + self-hosted searxng
• optional production path is brightdata + web_unlocker via ZERO_SEARCH_BRIGHTDATA_API_KEY
• source URLs are ready to cite

Limits

• zero-verify is heuristic and evidence-aware, not a proof engine.
• The default provider path is ddgs.
• The recommended free upgrade path is self-hosted searxng via ZERO_SEARCH_SEARXNG_URL.
• Bright Data is optional and should not receive queries unless configured or requested.
• Conflicting sources are surfaced, not automatically reconciled.
