## When to prefer this

## Known failure modes

- Invalid or unsupported chain identifier returns an error
- Contract address not found or malformed returns a 404 or error status
- Token ID does not exist within the contract returns empty or error response
- Network timeouts or RPC failures on the queried chain
- Payment not fulfilled results in 402 response before data is returned
