💡 How the API Works

Pre-computed Safaricom Index

Maps 58 Million Safaricom M-Pesa phone numbers across prefixes (0700–0729, 0740–0748, 0790–0799, 0110–0115) into SHA-256 cryptographic hashes.

Two-Tier Hybrid Storage

Combines Cloudflare KV for sub-50ms global edge cache hits with Cloudflare D1 distributed SQLite for full 58M dataset persistence.

Lazy Write-Through Caching

On initial D1 cache miss, the matching phone record is resolved and automatically warm-loaded into KV edge nodes for future instant requests.

⚡ Developer Integration

Query the endpoint directly via HTTP GET request:

curl -X GET "https://mpesa-phone.sh.co.ke/d6f1734a8897d7c5f1e47b1533b181f1c98c851e4e972e920ab082e655f23d16"
          

const token = 'd6f1734a8897d7c5f1e47b1533b181f1c98c851e4e972e920ab082e655f23d16';
const response = await fetch(`https://mpesa-phone.sh.co.ke/${token}`);
const data = await response.json();
console.log('Phone Number:', data.phone);
          

import requests

token = "d6f1734a8897d7c5f1e47b1533b181f1c98c851e4e972e920ab082e655f23d16"
res = requests.get(f"https://mpesa-phone.sh.co.ke/{token}")
print("Phone Number:", res.json()["phone"])
