# HEY Research Lab

> HEY Research Lab is the public record of building on Robinhood Chain (chain id 4663) — 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.

## Skills
- **Research one project** — Is this Robinhood Chain project still being built, and what did it ship? One project's important state from HEY's record: identity, builder activity, market con
- **Compare projects** — How do these projects' building records compare? Two to four published projects side by side with the page's own figures and gates. No winner is named. Input: {
- **What changed** — What changed on Robinhood Chain today or this week, or for one project? Changes HEY recorded on its canonical ledger, chain-wide or for one project, newest firs
- **Explain a published fact** — Why does HEY say a project is Shipping, Dormant or Still Building, or show a figure? The rule, the inputs, the lineage and the evidence ids, from persisted eval
- **Check what HEY knows** — What does HEY not know about this project? Per dimension, whether HEY measured it: MEASURED, NO_SOURCE, NOT_ENOUGH_YET, STALE, SOURCE_UNAVAILABLE, NOT_APPLICABL
- **Investigate a contract** — Who made this Robinhood Chain contract, and is it a known project's? The contract as HEY recorded it: project, creation, deployer, proxy and implementation hist
