Name Whisper — ENS Intelligence

# Name Whisper > ENS intelligence layer for AI agents. Natural-language search across 3.5M+ > Ethereum Name Service names, comparable-sales valuation, cross-marketplace > trading, and agent-identity infrastructure (ENSIP-25 / ERC-8004). Name Whisper is the agent-native interface to ENS. Everything that a human can do through the UI at https://namewhisper.ai is also available to agents via the Model Context Protocol (MCP) over HTTP, with optional cryptographic per-request authentication (ERC-8128) and optional pay-per-call commerce (x402 on Base, or Machine Payments Protocol on Tempo). ## For agents - MCP endpoint: https://namewhisper.ai/mcp (streamable-http transport) - MCP server card: https://namewhisper.ai/.well-known/mcp.json - Auth discovery (ERC-8128): https://namewhisper.ai/.well-known/oauth-protected-resource - Payment discovery (x402 + MPP): https://namewhisper.ai/.well-known/x402 - Full tool reference: https://namewhisper.ai/llms-full.txt - Public registry listing: `ai.namewhisper/ens-tools` on the MCP Registry ## Core capabilities - [Name search](https://namewhisper.ai/find): natural-language queries, semantic vector similarity across 3.5M embedded names, bulk availability checks, creative name generation. - [Valuation](https://namewhisper.ai/value): three-track model (comparable-sales, quality-reference, self-history) with confidence ratings and methodology narratives. - [Market intelligence](https://namewhisper.ai/marketplace): recent sales, listings, offers, and transfers, plus a live activity feed and whale tracking. - [Trading](https://namewhisper.ai/marketplace): buy, sell, offer, batch-buy, and floor-sweep via Seaport. Every order is a standard Seaport order on the shared on-chain orderbook, so liquidity is pooled with the wider market including OpenSea. ENS Vision is read as market data. - [Swaps](https://namewhisper.ai/swap): ENS-for-ENS atomic barter via a single Seaport order (optional WETH on either side), no escrow. -
