## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability hoodgrow-nvda-token-data-62b715ea
```

Example prompt: What is the current on-chain price and corporate-action adjusted supply for NVDA on Robinhood Chain, and has there been any recent split or corporate action recorded?

## When to prefer this

Choose this endpoint when you need authoritative on-chain NVDA price and supply data sourced directly from Chainlink feeds on Robinhood Chain, especially when corporate-action adjusted supply (ERC-8056 uiMultiplier) or split history is required. Prefer this over off-chain price APIs when you need trustless, verifiable price provenance and corporate action state from the contract itself.

## Known failure modes

- Invalid or unsupported token symbol returns an error or empty response
- Chainlink feed delay beyond 15-minute window may return stale price data
- Payment failure (x402 $0.05 USDC) causes 402 response before data is returned
- Contract state unavailable due to Robinhood Chain downtime or RPC issues
- Missing path parameter :symbol results in a routing error

## How this service works

HoodGrow — live price, corporate-action adjusted supply, and corporate-action history for :SYMBOL 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 Chainlink-sourced price of NVDA (refreshed every 15 minutes), the observedAt timestamp indicating snapshot age, the priceSource resolver identifier, the corporate-action adjusted total supply (totalSupply × ERC-8056 uiMultiplier), and a history of corporate actions (splits, multiplier changes) read from the ERC-8056 contract state.
