Fast Bulk DANA Checker API

I need an API that lets me push large batches of Indonesian DANA wallet numbers and instantly learn whether each one is valid and, when available, retrieve the registered name.

I need for today , i just need API Unlimited + Fast checking , max budget of me 200-250$
If you're serious, please chat me, I'll give you an example of the .txt number and what I mean. Just show me the quick process and the results you scanned, if they match my version, I'll take them.


Core requirements
• Endpoint accepts a plain list of numbers in any format—international, local, spaced, or concatenated. Your code should normalise each entry before processing.
• For every number returned I must see:
– “valid” (Boolean)
– “number” (the cleaned phone)
– “name” (if DANA discloses it; otherwise null)
• Response must be in JSON and include the results in the same order I sent them.
• Concurrency: the service will be hit with bulk requests; aim for sub-second look-ups on hundreds of numbers at once.
• Provide simple token-based authentication so I can throttle or revoke access if needed.
• Supply clear documentation plus a quick Postman collection or cURL example so I can test immediately.

Implementation notes
Use any stack you are comfortable with—Node, Python (FastAPI), Go, PHP, etc.—as long as deployment is straightforward on a standard VPS. Robust error handling and concise logging are expected.

Deliverables
1. Source code and build/run instructions
2. Live endpoint (or Docker image) ready for smoke testing
3. Brief PDF/Markdown doc covering routes, parameters, sample responses, and rate-limits

If you’ve previously integrated with DANA or other Indonesian e-wallets, let me know; proven speed and accuracy will help me decide quickly.
