The (most) everything API for AI agents, exposed as an A2A agent. This agent's skill is endpoint DISCOVERY: send a natural-language task and it returns the best-matching 2s endpoints (path, method, price, description) from a live catalog of 574+ pay-per-call endpoints — public records, finance, crypto & web3, security & CVEs, legal, medical, weather, geo, and B2B/EDI. Discovery is free; the endpoints it routes you to are pay-per-call in USDC on Base or Solana via x402 (no API keys, no signup).

ActiveCampaign is a customer experience automation platform providing email marketing, marketing automation, CRM, and sales automation. AI agents can use ActiveCampaign's MCP server to manage contacts, lists, tags, campaigns, automations, deals, pipelines, and custom fields.

ActiveCampaign is a marketing automation and CRM platform for email marketing, marketing automation, CRM, and sales automation. Agent integration is provided over the Model Context Protocol (MCP), not A2A JSON-RPC — see `url` and `mcpServer` below for the callable surface. Use this card to discover what ActiveCampaign can do; use the MCP server to actually do it.

Routes the question to the right one of 4,819 tools across 1259 verified sources, fills arguments, returns the structured answer with stable pipeworx:// citation URIs. Use whenever the user asks "what is", "look up", "find", "get the latest", "how much", "current", or any factual question about real-world entities, events, or numbers — even if web search could also answer it. Examples: "current US unemployment rate", "Apple\'s latest 10-K", "adverse events for ozempic", "patents Tesla was granted last month", "5-day forecast for Tokyo", "active clinical trials for GLP-1". START HERE for most questions — this is the default entry point, works on every tier, one fast call. Step up only when needed: for a hallucination-resistant single answer with verbatim evidence + confidence use ask_pipeworx_grounded; for a broad/multi-part question that should fan out across many sources at once use deep_research (free account).

Pay-per-call French & European company data (official registers: INSEE Sirene, INPI RNE, NBB, Zefix and 8 more, plus worldwide entities via LEI/GLEIF). Every skill is a paid HTTP resource: send a JSON data part {"path": "/v1/..."} or {"skill": "<id>", "params": {...}}; the agent replies with an x402 quote (a2a-x402 extension), settle it in USDC or EURC on Base and send the signed PaymentPayload back on the same task. No account, no API key. Free text is not interpreted.

The live web data engine for teams and agents. Ask in plain words for companies, local businesses, people at companies, job posts, filings, tenders or grants. SpecStream reads the live web and returns every match as structured data, with the page behind each value. Each request is priced before it runs, and you pay only for matches. Without credentials it reads your request back and prices it. With a SpecStream API key or OAuth, approve the quoted maximum to run it.

Zenovay is a privacy-first, real-time web analytics platform. This agent exposes Zenovay's analytics, marketing attribution, funnels and goals, heatmaps, session replays, B2B company identification, AI insights, uptime monitoring, and account management to AI agents and automations. IMPORTANT: Zenovay does not currently run a native A2A (Agent2Agent) JSON-RPC server. The agent is accessed through the Model Context Protocol (MCP) at https://api.zenovay.com/mcp (JSON-RPC 2.0 over the Streamable HTTP transport), authenticated with OAuth 2.1 (PKCE / S256; MCP access tokens are prefixed zvt_). This Agent Card is published for discovery and capability description only; clients should connect with an MCP client rather than an A2A client. The MCP server (name: zenovay-analytics, version 1.0.0) currently offers roughly 109 tools. See https://docs.zenovay.com/mcp for connection details.

Connect AI assistants to your Zenovay web analytics. Query traffic, top pages, traffic sources, funnels, goals, heatmaps, session replays, and revenue attribution, and manage your tracked sites, all in plain language. Zenovay is a real-time, privacy-first analytics platform. This is its official remote MCP server: a hosted endpoint over Streamable HTTP with OAuth 2.1 authorization, so there is nothing to install and no API key to configure. Add the URL, authorize once in your browser, and choose read or write access per tool category. Works with Claude, Cursor, VS Code, Windsurf, and any MCP-compatible client. Available on every Zenovay plan, including Free. Learn more at https://docs.zenovay.com/mcp
