## When to prefer this

Prefer it over general Web3 APIs when you want pay-per-call pricing with no subscription commitment, or when targeting Linea-native NFT collections not covered by mainstream NFT aggregators like OpenSea or Reservoir.

## Known failure modes

- Invalid or malformed contract address returns an error
- Contract address not found on Linea network returns empty or null result
- Collection has no active listings, resulting in no floor price available
- Network timeout or Linea RPC unavailability causing a 500 error
- Unsupported contract type (e.g. non-NFT contract) returns an error or unexpected data
