| Standard JSON-RPC (`eth_*`) errors | Standard Ethereum JSON-RPC error codes likely apply, but this is an assumption, not a confirmed Lumia value. See [`/reference/json-rpc-api`](https://app.gitbook.com/s/chmhPiVNAafGw48c4oU2/reference/json-rpc-api). |
| KYC Verifier API                   | No explicit error codes; only a `status` enum (`success`, `approved`, `failed`, pending states). See [`/reference/rest-apis/kyc-verifier-api`](https://app.gitbook.com/s/chmhPiVNAafGw48c4oU2/reference/rest-apis).  |
