I have a MySQL database that stores stock-market-related records. I need a lightweight script or micro-service that will: • Query the required rows on a schedule or on demand, • Convert the result set into a clean JSON payload, and • Push that payload to a remote endpoint via a standard webhook (HTTP POST with a bearer token). The table structure is already in place; I will explain the field names you should map. The JSON shape has to match a small schema I’ll share, but it is simple key-value pairs—nothing nested beyond one level. Code can be in Python, Node.js, or PHP as long as it runs reliably on a Linux server. Use parameterised queries (or an ORM if you prefer) so there is zero risk of SQL injection, and make sure any credentials sit in an external config file or environment variables. The webhook must return a 200 OK; if it does not, the job should retry with exponential back-off and log the response for review. Deliverables: • Source code with clear inline comments. • A README covering setup, cron/scheduler instructions, and example curl test. • A sample output JSON that passes the endpoint’s validation. Once delivered, I’ll test against the live endpoint and sign off as soon as the data posts successfully and the logs confirm acknowledgements.
