-Initiates the Tez request procedure. The user provides their address, the amount of Tez they want, and captcha token (optional). If `DISABLE_CHALLENGES` is `true`, only the `/verify` endpoint should be used.

+**Solving the Challenge**:
+You need to find a nonce such that the SHA-256 hash of the concatenated string (challenge + nonce) begins with a number of zeros equivalent to the given `difficulty`. For instance, if the difficulty is 4, then the hash should start with four leading zeros, e.g., `0000abcd1234...`. The nonce is an arbitrary number that is iteratively increased until the condition is met.
+
+**Pseudocode**:
+
+```pseudocode
+nonce = 0
+do {
+    combined_string = challenge_string + nonce
+    hash_result = sha256(combined_string)
+    nonce++
+} while (hash_result does not start with `difficulty` number of zero bytes)
+```
+
+### **POST `/verify`**
 
-Allows users to submit solutions to the challenges. The user provides their address, nonce, and solution string.
+Submit challenge solutions and receive Tez.
