You send SMS. You get billed later. You don't know why: estimate SMS cost in Python

The introduction of an estimation API in the BridgeXAPI service represents a significant shift from traditional SMS gateway services. Typically, these services provide pricing information only after messages have been sent and charges incurred. However, with BridgeXAPI's new feature, developers can now predict costs before sending SMS messages, enabling more sophisticated and cost-effective management of communication pipelines.

Key Benefits of Estimation API

1. Pre-Send Approval Logic: Before initiating a message send operation, the system can check if there is sufficient balance to cover the estimated cost. This prevents unexpected overages or insufficient funds issues.

2. Balance-Aware Execution: Systems can be designed to automatically switch routes based on available balance and expected costs, ensuring that messages are sent through the most economical route possible.

3. Route Cost Comparison: By comparing estimated costs across different routes (e.g., Route 1 vs. Route 2), developers can choose the least expensive option for sending SMS messages, optimizing overall spend.

4. Budget Controls: With real-time cost estimation, it becomes feasible to implement strict budget controls and alerts when approaching or exceeding predefined spending limits.

5. Safer OTP and Transactional Pipelines: For critical applications like one-time passwords (OT
