GroundRoute: Web Search for AI Agents across 6 Engines ($10 free credit)

GroundRoute gives your AI agent web search across six engines (Serper, Brave, Exa, Tavily, Firecrawl, Perplexity) through a single search tool. That one tool covers web, news, and academic search, synthesized answers with citations, and full-page fetch, all selectable with a mode parameter, so you never wire up or pay for six separate APIs. It routes each query to the cheapest engine that meets a quality bar, caches repeats, and fails over automatically. Pricing is gain-share: you keep about half the cache savings, so it never costs more than going direct. Bring your own engine keys (BYOK) or let GroundRoute manage them. New accounts start with $10 in free search credit, no card. Get a key at https://groundroute.ai/keys, and see the live benchmark across all six engines (170 real agent queries) at groundroute.ai/state-of-ai-search.

16 security checks for agents: Solidity source and verified-contract scans, a pre-interaction contract check, proxy detection, calldata decoding, token allowances, agent-skill and MCP package scans before installing, phishing URL checks and OFAC sanctions screening (single or batch), domain, RDAP, security-header and email checks, hidden-Unicode inspection. Results are automated and heuristic, not an audit. Hosted remote MCP server (streamable HTTP), no key and no account: each tool has a free daily allowance, then pays per call in USDC on Base or Polygon via x402 (most tools USD 0.001-0.02). The full 170-tool server is tanod-labs/tanod.

Current production WhatsApp templates send in French. Built for Moroccan salons, barbers, beauty institutes, medical practices and detailing

Star Ninja reports sky darkness, cloud cover and moonless hours for a night-sky spot you name. Give it a start point and a spot, both as coordinates, and it returns: Darkness: the spot's darkness band, from satellite light-pollution data. This is a yearly average, not a live reading. Distance: the straight-line distance from your start, with a rough drive time. Nights: for each of the coming nights, the cloud forecast, when full darkness starts and ends, the moonless hours, and how much of the Moon is lit. A map link: the same start and spot on the Star Ninja map. Use it when someone asks where or when they can see stars, to check a place they name or compare several. It does not find, rank or recommend spots, plan routes, or check access or safety. Forecasts change, and the drive time is an estimate, not a route. Free. No account or API key. One read-only tool: Check a stargazing spot.

NOAA SWPC space weather: storm scales, Kp index, aurora forecasts, solar wind, activity, alerts.

Production MCP server providing all of APIbase's real-world API tools across 30+ categories. Live catalog and current count: apibase.pro/llms.txt. Pay-per-call via x402 USDC micropayments on Base + MPP USDC on Tempo.

Search and read a corpus of 796 verified layers at the seams between fields, built one night at a time by autonomous AI instances under one rule: never lie about anything real. Every claim on every page is checked in-page or cited, and every page ships a verifier you can run. searchstrata is the same hybrid engine the site's own search box runs, shared verbatim: static Model2Vec word vectors plus BM25 over the corpus and over each page's full text, fused by reciprocal rank, with per-channel diagnostics on every result. readstratum returns a layer's own source. skynow computes a live ephemeris. leavedeposition goes through the same public door, gate and rate limit a human uses, because the house principle is that there is no distinction between an agent and a human: every tool here is a door a person already has.

NASA space data — Near Earth Objects (asteroid tracking & hazard assessment), Space Weather (solar flares, CMEs, geomagnetic storms via DONKI), and Astronomy Picture of the Day.

Fastio gives your team and AI agents a workspace for each project, bringing source files, comments and new work together. Connect a compatible MCP client to find files, answer questions from project material, and save results where the team can review and use them. Sign in through Fastio and choose the workspaces the connection can reach. Read Only connections expose read tools; Read & Write connections also allow changes. Files and folders: browse, read, upload, and organize files, with version history and trash. Search: find files by keyword; search file content and meaning when Deep Indexing is enabled and files have been processed. Metadata: read, set, and search metadata fields, including extracted fields where available. Shares create and manage shares for sending or collecting files. Comments and members: read and add comments, and manage workspace membership within your permissions. Activity: search workspace events to see what changed. Ho
