# NameWhisper

**Canonical:** https://apis.io/providers/namewhisper-ai/  
**Website:** https://namewhisper.ai/  
**APIs profiled:** 3

Name Whisper is an ENS (Ethereum Name Service) intelligence layer built for AI agents: natural-language search across 3.5M indexed .eth names, three-track valuation, live market data, wallet portfolios, and non-custodial transaction building for registration, renewal, Seaport listings and offers, resolver records, NameWrapper operations and ERC-8004 / ENSIP-25 agent identity. Everything is exposed as a public, anonymous remote MCP server at https://namewhisper.ai/mcp (44 tools, streamable-http, on the MCP Registry as ai.namewhisper/ens-tools) and an A2A 0.3.0 agent at https://namewhisper.ai/a2a, described by an agent card, an MCP server card, RFC 8414 / 9728 auth metadata, an RFC 9727 api-catalog, an llms.txt and provider-published Agent Skills. Identity is opt-in ERC-8128 signed requests; x402 and MPP payments are wired but dormant. The service never holds keys - every mutating tool returns unsigned calldata for the caller's wallet. No OpenAPI is published for the REST twins.
