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 578+ 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).

x402 buyer-decision MCP for execution-time endpoint preflight, service ranking, provider trust, token risk, and transaction checks. Paid answers are compact policy JSON, not broad reports.

B2B lead quality scoring — validate email, assess domain credibility, and score leads A-F before you invest outreach time. Also provides raw email deliverability and MX verification.

Enrich leads and business contacts: agentic lead-session, reverse phone, person search, websearch, B2B lead search. x402 USDC + free trial + MCP.

Global regulatory intelligence API. Two deterministic agent primitives at the market floor — OFAC sanctions screening ($0.02, SDN + Consolidated lists, alias-aware) and EU VAT validation via VIES ($0.01) — returning official source rows verbatim with no LLM. Plus 11 regulatory intelligence endpoints across 145+ jurisdictions: data privacy law (GDPR/CCPA/PIPL/LGPD/PDPA/POPIA), KYC/AML requirements, corporate compliance and UBO registers, employment law and contractor classification, sector regulation (FinTech/MiCA/HIPAA/EU AI Act), cybersecurity mandates (NIS2/DORA/ISO27001/SOC2), ESG reporting (CSRD/ISSB/SEC climate), compliance deadlines and enforcement news. Pay-per-query via x402 on Base.

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.

Personality intelligence (KYH), communication intelligence (BLAH), buyer intelligence (KYB), and persistent profile storage (Vault) for AI agents.

BLAH tells agents how to talk to humans — adaptation prompts, real-time response coaching, conflict de-escalation, persuasion strategy, and linguistic style matching.
