I want to roll out a single API panel that lets my platform handle mobile recharges, utility bill payments, and DTH recharges in one place. The goal is a clean set of endpoints I can drop straight into my current codebase, together with a lightweight web interface where I can view traffic, transaction status, and basic error logs. Here is what I need delivered: • RESTful or JSON-RPC endpoints for the three services listed above. • A minimal dashboard (PHP, Node, or Python—your call) showing transaction history, amounts, and provider response codes. • Clear, commented documentation that lets another developer — or future me — wire new front-end screens without guessing. If you have suggestions on best-practice security or rate-limiting, mention them in your bid; I’m flexible as long as integration stays straightforward.
