+### Claim Response Success & Failure
+
+The API returns a **JSON array**, where each object corresponds to a faucet
+claim attempt. Each object contains:
+
+- `faucet_info`: A string identifying the faucet (e.g., `CalibnetFIL`,
+  `CalibnetUSDFC`)
+
+And either:
+
+- `tx_hash`: A string containing the transaction hash **if the claim was
+  successful**,  
+  **or**
+- `error`: An object containing the error details **if the claim failed**
+
+---
+
+## Examples
+
+### Success
+
