Web search and URL extraction for Hermes — now with Routing v2: benchmarked, class-aware auto-routing across the providers your keys can actually support. web_extract_plus(provider="auto") defaults to Tavily-first extraction for fast, reliable fetches; Exa, Linkup, Firecrawl, Parallel, and You.com remain fallback paths when available.

web-search-plus adds two Hermes tools:

• web_search_plus — routed multi-provider web search with quality diagnostics
• web_extract_plus — clean URL extraction via provider backends

Ported from web-search-plus-plugin for the Hermes Agent plugin API.

Most web-search tools fail in one of two boring ways: they hard-code a single provider, or they pretend every user has every API key. This plugin is capability-based instead:

• No global required key. Configure one search-capable provider and search works.
• Extraction is additive. Add Linkup, Firecrawl, Tavily, Exa, Parallel, or You.com for URL extraction.
• Routing v2 is conservative. You.com, Serper, Exa, Firecrawl, Tavily, and Linkup form the default search pool; Brave, SerpBase, Querit, Parallel, and Perplexity/Kilo stay explicit/guarded unless opted in.
• Costs stay bounded. Research mode caps provider work and keeps partial results when extraction fails.

# 1) Install and enable the Hermes plugin
hermes plugins install robbyczgw-cla/hermes-web-search-plus --enable

# 2) Configure provider keys with the standalone setup wizard
python ~/.hermes/plugins/web-search-plus/setup.py status
python ~/.hermes/plugins/web-search-plus/setup.py setup

# Bare setup prompts every supported provider; press Enter to skip what you do not have.
# Fast starter preset if you want the short path:
# python ~/.hermes/plugins/web-search-plus/setup.py setup --preset starter
# YOU_API_KEY=...      # fast Routing v2 core provider
# SERPER_API_KEY=...   # reliable Google-like fallback
# LINKUP_API_KEY=...   # clean extraction

# 3) Restart/reload Hermes so plugin tools are registered
# CLI: exit and start `hermes` again, or use /reset in-session
# Gateway/Telegram: /restart, then /reset

# 4) Optional shell smoke test
cd ~/.hermes/plugins/web-search-plus
python3 search.py --query "Hermes Agent latest release" --provider auto --quality-report

Notes:

• Plugin install clones into ~/.hermes/plugins/web-search-plus.
• Keys are written to the active Hermes environment file by the setup helper; they should never be committed to the repo.
• Python 3.8+ is required. Normal Hermes plugin installation handles runtime dependencies; manual development can use python3 -m pip install -r requirements.txt inside the Hermes/plugin environment.

• User Guide — detailed setup, provider tuning, routing, extraction, reliability, and cost controls.
• FAQ — common setup, SerpBase auto-allow, provider selection, cache, quota, and troubleshooting questions.
• Architecture — plugin boundary, routing engine, auto-allow gate, cache/cooldown state, data flow, and provider-extension notes.

The setup wizard is intentionally nicer than “paste keys and pray”:

python ~/.hermes/plugins/web-search-plus/setup.py status
python ~/.hermes/plugins/web-search-plus/setup.py list
python ~/.hermes/plugins/web-search-plus/setup.py setup
python ~/.hermes/plugins/web-search-plus/setup.py setup --preset starter --open
python ~/.hermes/plugins/web-search-plus/setup.py setup you linkup --env-path ~/.hermes/.env

Presets:

• default / all — prompt every supported provider; Enter skips missing keys.
• starter — You.com + Serper + Linkup; best Routing v2 first-run setup.
• lean — You.com + Linkup; small fast search + extraction pairing.
• search — You.com + Serper + Exa + Firecrawl + Tavily + Linkup; full default Routing v2 pool.
• extract — Firecrawl + Linkup + Exa + Tavily; extraction-heavy setup.
• all — prompt for every supported provider.

The CLI never prints secret values. It writes keys into the active Hermes .env file, then reminds you to restart Hermes or run /reset so the tools re-register.

Key setup and routing behavior are separate on purpose: secrets live in .env; provider behavior lives in config.json.

# Show provider/key status and routing preferences
python ~/.hermes/plugins/web-search-plus/setup.py status --json
python ~/.hermes/plugins/web-search-plus/setup.py config show --json

# Prefer one fixed provider instead of auto-routing
python ~/.hermes/plugins/web-search-plus/setup.py config set-default you

# Turn auto-routing back on
python ~/.hermes/plugins/web-search-plus/setup.py config set-routing on

# Tune auto-routing order and fallback
python ~/.hermes/plugins/web-search-plus/setup.py config set-priority you,serper,exa,firecrawl,tavily,linkup
python ~/.hermes/plugins/web-search-plus/setup.py config set-fallback serper
python ~/.hermes/plugins/web-search-plus/setup.py config disable perplexity
python ~/.hermes/plugins/web-search-plus/setup.py config enable perplexity
python ~/.hermes/plugins/web-search-plus/setup.py config set-auto-allow serpbase off
python ~/.hermes/plugins/web-search-plus/setup.py config set-auto-allow serpbase on
python ~/.hermes/plugins/web-search-plus/setup.py config set-threshold 0.45

# Preview changes without touching disk
python ~/.hermes/plugins/web-search-plus/setup.py config set-default you --dry-run

Notes:

• set-default <provider> disables auto-routing and makes --provider auto resolve to that provider.
• set-routing on restores query-based routing while keeping the saved default for later.
• set-priority accepts comma-separated provider names, normalizes case/whitespace, and ignores duplicates with a warning.
• set-auto-allow <provider> off keeps a configured provider available for explicit calls while preventing auto-routing/fallback from selecting it. Brave, SerpBase, Querit, Perplexity, and Kilo Perplexity default to off here.
• setup.py --config-path /path/to/config.json points the helper at a custom config; WEB_SEARCH_PLUS_CONFIG=/path/to/config.json points search.py at the same file.
• config reset --yes backs up the existing file before writing fresh defaults.

setup.py status --plain reports this directly:

web-search-plus is configured. Providers: You.com, Serper, Linkup
Capabilities: search=yes, extraction=yes

Use this when the agent needs search results and routing metadata.

web_search_plus(query="Graz weather today")
# → auto-routed current-info search

web_search_plus(query="Singapore CPI latest", provider="you")
# → force You.com search

web_search_plus(query="alternatives to Notion", provider="exa")
# → semantic discovery

web_search_plus(query="compare recent reviews of turntables under 1000", mode="research", research_time_budget=45)
# → opt-in multi-provider research; keeps partial results if extraction hits errors/budget

web_search_plus(query="best bookshelf speakers under 1000", quality_report=True)
# → normal search plus routing/result-quality diagnostics

Parameters:

Use this when you already have URLs and want clean content.

web_extract_plus(urls=["https://example.com"], provider="firecrawl")
# → extract clean markdown from a URL

web_extract_plus(urls=["https://docs.linkup.so"], provider="linkup", render_js=False)
# → Linkup fetch endpoint

Auto extraction currently tries Tavily, then Exa, Linkup, Parallel, Firecrawl, and You.com when keys are available. Tavily is the fast reliable default; Exa is the fast docs/academic backup; Linkup stays the clean long-form/RAG fallback; Parallel is the excerpt-heavy LLM-ready backup; Firecrawl remains the robust scraper safety net; You.com is the final fallback.

Parameters:

Routing v2 is benchmarked and class-aware. It detects language/script hints and query classes such as multilingual current news, AT shopping/local, docs/API, GitHub, academic/arXiv, Reddit/community, CVE/security, official/regulatory, finance/IR, weather/local, OSS discovery, and briefing/synthesis-style searches. You.com, Serper, Exa, Firecrawl, Tavily, and Linkup are the conservative default auto-search pool. Brave, SerpBase, Querit, Parallel, Perplexity, and Kilo Perplexity default to auto_allow=false: configure their keys to call them explicitly, or opt them into automatic routing with setup.py config set-auto-allow <provider> on.

• Provider cooldowns: failed providers are skipped for 1 hour before retry.
• Research budget: mode="research" checks the wall-clock budget between provider calls and extraction steps.
• Partial results: search results already collected are preserved if extraction fails or times out.
• Truthful warnings: missing extraction keys, quota failures, empty results, and budget exhaustion appear in response metadata.
