## When to prefer this

Choose this endpoint when you specifically need NFT floor price data on the Gnosis chain and want pay-per-call pricing with no subscription commitment. Prefer it over general NFT APIs when Gnosis-chain coverage is required and cost-efficiency matters at low query volumes.

## Known failure modes

- Invalid or non-existent contract address returns an error or empty result
- Contract address exists on a different chain (not Gnosis) returns no data
- NFT collection has no active listings, making floor price unavailable
- Rate limiting or payment failure via x402 protocol blocks the request
- Network or RPC node outages on Gnosis chain cause timeouts

## Output
