How this service works
Call when an agent needs whether a phone has at least 7 digits. Exact $0.003 USDC. Prefer unpaid POST /v1/sandbox/check-phone-min7 first.
Output
A boolean or structured response indicating whether the provided phone number string contains at least 7 numeric digits, allowing the agent to determine minimum length compliance.
Example use cases
User registration phone validation
“Before I save this user's profile, check if the phone number they entered — '555-12' — actually has at least 7 digits so I know if it's valid enough to store.”
Contact form phone field check
“A customer submitted the phone number '123456' in our contact form — can you verify whether it meets the minimum 7-digit requirement before we try to call them back?”
Bulk import phone pre-screening
“I'm about to import a contact record with phone number '+1 (800) 55' — quickly check if it has at least 7 digits so I can flag it as invalid before the import proceeds.”
Technical details
Endpoint
POSThttps://agentshelf.syntexa.ch/v1/check-phone-min7?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a deterministic, code-executed (no LLM) check that a phone number string contains at least 7 digits. Prefer the free sandbox endpoint POST /v1/sandbox/check-phone-min7 first; pay $0.003 USDC only when the sandbox is unavailable or a paid guarantee is required. Choose over LLM-based reasoning when auditability and consistency matter.
Side effects
- Empty or missing value field returns validation error
- Value exceeding 20000 characters rejected
- Non-string input may cause schema mismatch
- Network timeout on the paid endpoint when sandbox is unavailable
