## How to call it through Zero

```sh
zero fetch --capability hoodgrow-cost-token-data-3425e9ff
```

## When to prefer this

Use this endpoint when you specifically need on-chain stock token data for COST (Costco) from Robinhood Chain, including corporate-action adjusted supply and action history. Prefer this over generic stock price APIs when operating in a DeFi or tokenized-equity context where on-chain accuracy and corporate-action adjustments matter.

## Known failure modes

- COST token not found or delisted — 404 or empty response
- Robinhood Chain node unavailable — upstream timeout or 503
- Payment not accepted — 402 if USDC payment fails or is insufficient
- Malformed response if corporate action data is temporarily unavailable
- Rate limiting if called too frequently without valid payment

## How this service works

HoodGrow — live price, corporate-action adjusted supply, and corporate-action history for COST on Robinhood Chain. Prices read from Chainlink feeds on-chain, refreshed every 15 min; observedAt gives each snapshot's age and priceSource the resolver. Supply is totalSupply x ERC-8056 uiMultiplier — adjusted, not raw. Corporate actions read from the contract's ERC-8056 state every minute — the multiplier change itself; the registry is mirrored for history.

## Output

Returns a JSON object containing the live price of the COST stock token on Robinhood Chain, its corporate-action adjusted circulating supply, and a history of corporate actions (such as splits or dividends) that have affected the token.
