## When to prefer this

Choose this endpoint when you specifically need on-chain holder distribution and supply dynamics (mint/burn) for NVDA on Robinhood Chain, as opposed to price data or DeFi pool liquidity. It is the right choice when analyzing tokenization health, whale risk, or supply inflation for this specific equity token.

## Known failure modes

- Stale data if the 4-hour refresh cycle has not completed yet
- Token symbol mismatch if NVDA is delisted or renamed on Robinhood Chain
- Payment failure if x402 USDC payment of $0.05 is not completed
- Rate limiting or HTTP 402 if payment is not attached to the request
- Data gaps if explorer source is temporarily unavailable
