  summary: The public record of building on Robinhood Chain — every ship with its source.
  description: '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. Every path below begins with /api on https://heyresearch.xyz — an index answers at https://heyresearch.xyz/api — for Robinhood Chain (chainId 4663). Token identity is (chainId, contract), never a symbol. $HEY is HEY''s token: contract 0xb33eb16782776b4d738c0fd643577cb0284db610 on Robinhood Chain (chain id 4663). Research it like any token at https://heyresearch.xyz/api/hey/profile


    HEY Research Lab is the product''s brand name and the name of its own project record; it is spelled one way everywhere. **Semantic traps — read before using any figure:**

    - Unknown is not zero: an absent or null field means HEY does not know, never 0, false, [] or "none". - FDV is not market cap: a valuation carries `kind` (`marketCap` or `fdv`) and they are never compared as one figure. - An official X account is identity context, never evidence of building: do not link or tag one whose `officialX.linkHeld` is set or whose `officialX.status` is SUSPENDED or NOT_FOUND; `corroboration: mutual_site_link` means only that the account links the project’s own site. - Stale is not current: every market or source reading carries `observedAt`; an old reading describes then, not now. - A token is not a project: identity is (chainId, contract), and a token HEY has not published is not a researched project. - Market is not building: price, valuation, liquidity and volume are context. Market figures (price, valuation, liquidity, volume) never feed activity status, Build Momentum or the Radar. The Discovery Gap is the one place market attention enters: it compares Build Momentum against market attention, measured on an active market only (elsewhere it is withheld, never 0). **Evidence.** Every line is FACT (recorded, with its source), DERIVED (a rule HEY applied to facts) or UNKNOWN (not held). Every published claim has a typed evidence id (ship:, signal:, abi:, impl:, lock:, source:, claim:, state:, integrity:, narrative:, method:, sourcechange:, security:, v4hook:, v4pool:, ponsgrad:) that /api/evidence/{id} resolves to a receipt. **What HEY does not do:**

    - 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. **Access.** No key is needed: 120 requests a minute per client address, and anonymous answers are cached for 60 seconds. An API key (`Authorization: Bearer ` or `x-api-key`) names your integration and unlocks the bulk reads; a free key keeps 120 a minute, in a bucket of its own rather than one shared by every caller on your address (holder keys: Holder 600, Holder+ 1200 a minute). Every key carries a monthly allowance (a spent allowance answers 429 `quota` until the month resets), and keyed answers are private (`cache-control: private, no-store`), never edge-cached. CORS is open for GET.'

      summary: HEY's own freshness and health
      description: When each pipeline last ran and whether it is fresh. `build` is the build serving the answer, as `/api/health` reports it (since 2026-10-02); `summaryBuild` (additive) is the build that wrote the hourly summary `capturedAt` dates. A failing integrity audit (a data-quality check) makes `verdict` at least warn — never critical by itself since 2026-11-10 — with a headline naming the check, and `integrity.failing` (additive, 2026-10-03) names the checks; `catalog.indexed` is the hidden launch records (not the catalogue's "indexed"), with `catalog.hidden` and `catalog.hiddenAsOf` (additive) naming and dating it by the hourly summary; `catalog.listedTokenOnly` (additive, 2026-10-12) is the part of `catalog.published` that is a listed token with no builder evidence and no live market, counted in `published`, never subtracted.
