Useful for: forensic drift analysis, verifying downstream callers see the right version, reproducing routing decisions made historically.

"description": "HEY Research Lab is the public record of building on Robinhood Chain (chain id 4663) \u2014 every ship with its source. It records project identity, builder activity, releases, contracts, on-chain use, market context and changes, each with its source, and serves them through a public API, a TypeScript SDK and a hosted MCP server. Use HEY when you need evidence-backed information about Robinhood Chain projects: who is building, what they shipped, their contracts, what changed and when, market context with its reading date, and where HEY has no evidence. Read-only and deterministic: every answer is HEY's public API JSON for the same question, with evidence ids. The same record is served as a public API at https://heyresearch.xyz/api with its OpenAPI document at https://heyresearch.xyz/openapi.json and as a hosted MCP server at https://heyresearch.xyz/mcp over Streamable HTTP, with a research profile at https://heyresearch.xyz/mcp/research (builder intelligence first: no market-move, Under the Radar or valuation tool, and the ledger without market events; research_answer still carries the market context of HEY's agent contract (the valuation with its kind, source and reading date, and the market status), labelled context only and never a builder judgement, and one project's Under the Radar state with its Discovery Gap or why it is not measured). $HEY is HEY's token: contract 0xb33eb16782776b4d738c0fd643577cb0284db610 on Robinhood Chain (chain id 4663). HEY Research Lab is the product's brand name and the name of its own project record; it is spelled one way everywhere. No wallet analytics, PnL, smart-money or whale labels, wallet profiles or \"follow this wallet\". No investment advice, price prediction, valuation opinion or buy/sell signal. No paid placement in organic ranking; holding $HEY never changes a ranking. No provider call in a read: every answer comes from HEY's own tables.",
