```

Example prompt: Check the Chainlink oracle deviation for NVDA on Robinhood Chain — I want to know how far the on-chain price is from the actual equity price right now.

## When to prefer this

Choose this endpoint when you need to verify that tokenized stock or ETF prices on Robinhood Chain accurately reflect their real-world equity counterparts, or when hunting for dislocation-based arbitrage opportunities. It is specifically designed for Robinhood Chain's tokenized equity ecosystem and Chainlink oracle feeds — not a generic crypto price feed or DEX price checker.

## Known failure modes

- Ticker not supported — no Chainlink feed exists for the requested symbol
- Real equity market is closed and reference price may be stale
- Oracle feed temporarily unavailable or delayed
- Invalid ticker format returns a validation error
- Payment failure or insufficient USDC balance blocks the call

## How this service works

Chainlink oracle health for a tokenized stock on Robinhood Chain: reads the live onchain Chainlink feed (latestRoundData) and compares it to the DEX spot and the real equity price, with staleness (age vs heartbeat) and deviation %. Send { ticker }. Catch stale or dislocated oracles before they trigger bad liquidations. Reads onchain via Robinhood C

## Output

Returns the oracle-reported price for the specified ticker from the Chainlink feed on Robinhood Chain alongside the real equity market price, the absolute and/or percentage deviation between them, and any dislocation signals indicating whether the oracle is meaningfully out of sync with the underlying asset.
