## When to prefer this

Use this endpoint when you need authoritative on-chain NFT contract data across 46 supported chains, especially when you need verifiable blockchain data with pay-per-request pricing rather than a subscription model. Prefer over alternatives when querying lesser-known chains or needing cross-chain coverage.

## Known failure modes

- Invalid or malformed contract address returns 400 error
- Contract address not found on specified chain returns 404
- Unsupported chain identifier returns 400 or empty result
- Payment failure (x402) if USDC balance insufficient
- Rate limiting or timeout for high-traffic chains
