Why HoodGrow?

Robinhood put stocks on-chain. You can look up the chain's TVL anywhere. But nobody tracks the tokenized equities themselves: what's NVDA-on-chain's real supply after the split? How many wallets hold it? What did it trade at, on-chain, last Tuesday?

A tokenized stock is a strange new instrument — it splits, it pays dividends, it sits in DEX pools and lending markets, and the naive on-chain reads everyone reaches for first give wrong answers about it. That's the gap HoodGrow fills.

For every listed Robinhood Chain stock token, HoodGrow tracks price, Uniswap liquidity, holder-count trends and concentration, and OHLC price history for backtesting — plus Morpho and Uniswap yield data across the catalog.

The detail that matters most: totalSupply() is naively wrong for these tokens. A stock split on Robinhood Chain doesn't rewrite balances — it moves an on-chain uiMultiplier (ERC-8056). HoodGrow reports corporate-action-adjusted supply, correct through every split — here's how that works.

On top of the snapshots: a live whale-trade feed indexed straight from the DEX pools' swap events, and corporate actions (splits, dividends, name changes) detected from the token contracts' own on-chain state — checked every minute, so a split shows up minutes after it executes, not whenever a registry cache updates.

The next users of market data aren't humans — they're agents. An autonomous agent can't fill in a signup form, verify an email, or paste a credit card. So the agent API takes payment the way an agent can actually pay: per call, over x402 — USDC in, data out, no API key anywhere. Prepaid credit bundles and conventional API keys exist too, for callers that prefer them.

And for assistants that speak MCP, the whole API is one line away — no install, no signup, no key:

GET /api/agent/ping runs a real 402 challenge and settlement end to end — the smallest useful proof that an x402 client works. Humans don't need any of that: the token directory is free to browse. The market is new. The data source is ready.
