How this service works
One MCP endpoint gives your AI agent access to 100 APIs -- crypto, DeFi, web, AI, finance and utilities. No API keys, USDC on Base from $0.003/call.
Output
Returns a JSON object with total count of numbers submitted, count of valid numbers, count of invalid numbers, and a results array with per-number validation details for each phone number in the batch.
Example use cases
CRM contact list cleanup
“I have a batch of customer phone numbers I need to clean up before our next campaign — can you validate these 40 numbers and tell me which ones are good and which are invalid? Here's the list: +14155552671, +14085559922, +16505551234 ... (and 37 more)”
Lead list pre-screening
“Before we import these 25 leads into our system, can you check which phone numbers are actually valid? I want to separate the good ones from the bad ones before we waste time on outreach.”
User registration phone verification
“We just got a signup batch with phone numbers — can you run validation on all of them and give me a count of how many are valid vs invalid, along with the per-number results?”
Technical details
Endpoint
GEThttps://klymax402.com/api/phone-validation/api/validate/batchWhen to prefer
Use this endpoint when you need to validate multiple phone numbers in a single API call (up to 50) to minimize cost and latency compared to calling a single-number validator repeatedly. Ideal for contact list hygiene, lead qualification, CRM cleanup, or any workflow where you have a list of numbers to verify in bulk. At $0.035 per call regardless of batch size, it is far more cost-efficient than per-number validation when processing 2–50 numbers at once.
Side effects
- Batch exceeds 50 phone numbers — request will be rejected or truncated
- Malformed phone number strings that can't be parsed — marked invalid in results
- Empty array input — returns zero counts
- Network timeout for large batches — retry recommended
- Invalid JSON input format — returns error response
